BUSINESS

Overview

BTU International, founded in 1950 and headquartered in Billerica, Massachusetts, is a supplier of advanced thermal processing equipment to the electronics manufacturing and energy generation markets. We manufacture reflow furnaces for printed circuit board assembly as well as semiconductor wafer-level and die-level packaging equipment. In addition, we participate in the fast growing alternative energy market for which we provide thermal process equipment for the manufacturing of solar cells, fuel cells and nuclear fuels.

Our customers require high throughput, high yield and highly reliable thermal processing systems with tightly controlled temperature and atmospheric parameters. Our convection solder reflow systems are used to attach electronic components to the printed circuit boards, primarily in the advanced high-density surface mount segments of this market. In the semiconductor market, we participate in both wafer level and die level packaging, where our thermal processing systems are used to connect and seal integrated circuits into a package. Our customers in the energy generation market use our thermal systems to process silicon, ceramics and metal alloys which are used in solar cell, fuel cell and nuclear fuel manufacturing applications.

Industry Background

Electronics Markets

Demand for increasingly sophisticated electronic devices continues, and we expect that new technologies such as wireless networks, next generation cellular phones and personal digital assistants will drive future growth. Other types of electronic equipment are becoming more complex, including data communications equipment such as switches, routers and servers, broadband access products such as cable modems and Ethernet wireless accessories and consumer products such as automobile electronics and digital cameras. Integral to the growth in electronics are advances in technology that result in smaller, lighter and less expensive end products by increasing performance and reducing cost, size, weight and power requirements of electronic assemblies, printed circuit boards and semiconductors. In response to these developments, manufacturers are increasingly employing more sophisticated production and assembly techniques requiring more advanced manufacturing equipment.

Printed Circuit Board Assembly. In the printed circuit board assembly process, semiconductor and discreet-devices plus other components are attached to printed circuit boards. The attachment process, which creates a permanent physical and electrical bond, is called solder reflow or surface mount reflow. Industry observers estimate that the printed circuit board assembly market is growing at approximately 8% per year. In recent years, several of our markets have been implementing legislation that requires lead free solder processing of printed circuit boards and semiconductors. Japan’s lead free implementation deadline went effective in January 2006, while the implementation deadline for the European Union occurred in July 2006. As manufacturers have been replacing older thermal processing equipment which cannot process lead free solders, these market segments have seen an increased growth rate.

Wafer Level and Die Level Semiconductor Packaging. Semiconductor packaging processes include precision thermal processing steps. In advanced semiconductor packaging, processing takes place at both the wafer level and die level. At the wafer level, deposited solder must be thermally treated to form perfectly spherical “bumps.” At the die level, these bumps allow the integrated circuits to be bonded to the semiconductor package using precise thermal processes. Advancements in the semiconductor industry toward higher chip speeds, smaller form factors and reduced costs are driving the transition to wafer level packaging from the traditional wire bonding technique. Industry observers estimate that the semiconductor packaging market for thermal processing systems is growing at approximately 8% per year.

Alternative Energy Markets

The processing of advanced materials used in non-fossil fuel power generation applications is a significant target market. The rising cost of fossil fuels and environmental concerns have increased demand for power generation without the use of fossil fuels. For power generation applications, we serve the photovoltaic, fuel cell and nuclear fuel markets. We support our worldwide energy customers through our global sales and service network.

Photovoltaics. We offer continuous furnaces for solar cell manufacturing. Processes for this application include diffusion, anti-reflective coatings and thick film silver contact firing. Our Quartz muffle furnaces are used for phosphorus diffusion. Our Atmosphere Pressure Chemical Vapor Deposition furnaces are used in the deposition of anti-reflective coatings. These systems generally range in price from $180,000 to $600,000.

Fuel Cells. We offer a range of products used primarily in the manufacturing of Solid Oxide Fuel Cells (SOFCs). Typical processes performed by our equipment in this market are drying, sintering, co-firing and glass to metal sealing. In addition to supplying individual systems, we offer complete turnkey systems for the manufacture of fuel cell components. Drying applications are processed in our CHT series convection drying systems. Sintering and co-firing applications can be in excess of 1500°C. Our Convection Batch and Pusher furnaces are used for these processes. These systems generally range in price from $175,000 to $1.0 million.

Nuclear Fuel. We offer systems for sintering nuclear fuel. These processes operate at temperatures in the range of 1750°C in a hydrogen reduction atmosphere. Our most important product for this market is our patented Walking Beam system designed for high volume manufacture of nuclear fuels. It uses a walking beam transport system to eliminate friction associated with advanced thermal processing systems that use pusher technology. Walking Beam systems are used to sinter gadolinium and uranium pellets used for nuclear fuel generation. These systems generally sell for up to $2.4 million.

Across all markets, the need for more versatile, more reliable and more advanced capital equipment persists. In addition, the continued globalization of manufacturing and the shift to low cost regions such as China, particularly by electronics producers, has driven the demand for equipment with a lower cost of ownership.

Technological Challenges

Thermal processing systems present significant engineering challenges related to temperature control, atmosphere control, product handling, flux containment and disposal, and high system up time. Thermal processing systems must maintain accurate and uniform temperatures within their process chambers. The temperature within the process chamber is influenced by the rate at which components are moved through the system and the weight and density of the product. In addition, the thermal processing system’s heat convection rate must be varied and controlled as components and materials are processed. The chamber must also dispense heat uniformly across the product at precise temperatures to ensure maximum process uniformity. Also, products must be heated and cooled at closely preset rates in order to avoid damage caused by thermal stress. With the increasing use of lead free solder processes, the control window for temperature uniformity has become significantly more critical.

Another technological challenge for thermal processing systems is achieving precisely controlled atmospheric conditions within the process chamber. In order to facilitate thermal processing without contamination of or damage to the product, many thermal processing systems use a substantially oxygen-free atmosphere of nitrogen or hydrogen in their process chambers. If such gases are used, the entry of contaminating air must be minimized, even though the product enters and exits the system continuously from the ambient atmosphere. Maintaining a pure, safe and controlled atmosphere in the process chamber, while minimizing the consumption of nitrogen or hydrogen gases in order to reduce operating costs, presents significant engineering challenges.

Handling products in thermal processing systems requires highly reliable conveyance systems that can easily be converted to process a wide variety of products having different specifications, sometimes on side-by-side tracks through the process chamber. The product handling system must also fully support a wide variety of product sizes.

The mechanical components in thermal processing systems must operate almost continuously in a demanding, elevated temperature environment with frequent thermal cycles. The use of materials that are resistant to high temperature and thermal stress is important to achieving high reliability.

In applications using flux, the volatile compounds that are vaporized during the thermal processing cycle must be contained and collected so that they do not condense in the system or damage the environment. The efficient containment, collection and disposal of the flux are important factors in achieving high system up time, high throughput and reliability.

Our Solution

We deliver a broad range of thermal processing systems to serve the needs of manufacturers that require high throughput, process yields and reliability with tightly controlled process parameters. Our systems are designed to enable our customers to increase throughput and yield for printed circuit board assembly, advanced semiconductor packaging, and energy generation by providing precise atmospheric and temperature control. In addition to the expected high performance of our products, we believe maintaining the quality standards of our organization and our worldwide service and support are important to our success with industry leading global manufacturers.

We believe our customers continue to choose our products because of the following factors:

Accurate and Uniform Temperature. Our systems use convection, radiation and infrared heating technologies. Our high rate convection and fully enclosed coil heating modules are designed to provide controlled heating capacities across many different applications, thereby enabling our customers to maximize process uniformity and throughput. In addition, our systems are designed to apply heat uniformly across the product load, which is critical to ensure optimum processing. Heat up and cool down profiles are also closely controlled for process consistency and the protection of product.

Atmosphere Uniformity and Control. Our thermal processing systems are designed to provide precision control over atmospheric conditions within their process chambers by integrating our gas and physical curtain technologies. Our systems are designed to be capable of excluding virtually all oxygen from the critical process steps to maintain the safety and integrity of the process chamber atmosphere. In addition, our systems are intended to minimize the consumption of nitrogen or hydrogen, thereby reducing the operating cost of maintaining the atmosphere.

Repeatability from System to System. We design our systems with a goal of providing a high degree of repeatability from system to system through our atmospheric and temperature controls and the expected reliability of our systems. This repeatability is achieved through our industry leading closed loop convection technology that is intended to ensure the same convection rate regardless of change in altitude or temperature. This is a critical attribute because our customers must achieve uniform manufacturing performance in plants located throughout the world.

Processing Flexibility. Major electronics manufacturers process many sizes of printed circuit boards and often need rapid product changeover capabilities. Our systems can process printed circuit boards of different sizes with minimal or no reconfiguration. Rapid changeover reduces down time and increases manufacturing volume. In addition, our other thermal products can be configured for multiple process applications allowing for versatility in materials manufacturing.

Reliability. Our customers place a high premium on reliability. Reliability is a major contributor to low cost of ownership because high up time can increase the productivity and efficiency of an entire production line. We believe our systems are the most reliable advanced thermal processing systems in the world.

Systems Integration. We provide fully integrated systems that include automated handling of our products, as well as full software integration with our customers’ factory management systems. This allows our customers to monitor and analyze the process in real time from a central location.

Worldwide Customer Support. Our goal is to provide our customers with global technical service support, in depth process engineering support and rapid delivery of our systems and parts. We provide our customer support through our on-site direct service organization and our independent sales and service representatives, supplemented with twenty-four hours a day, seven days a week telephonic support and extensive customer training programs.

Our Strategy

Our objective is to be the leading provider of thermal processing systems to the electronics and energy generation markets. To achieve this goal and maximize value for our shareholders, our strategy is comprised of the following elements:

•

Further penetrate existing markets and customers by developing innovative products with a low cost of ownership and by offering exceptional customer support;

•

Continue to focus on cost reduction initiatives, including the improvement of our global supply chain and reduction in materials costs;

•

Expand our low-cost manufacturing and engineering operations in China;

•

Deepen relationships with key partners to facilitate product development for next generation technologies, particularly in the rapidly growing energy generation market.

Products

We supply a broad range of thermal processing systems for the electronics and energy generation markets. Our products are used for such applications as printed circuit board assembly, semiconductor packaging and advanced material processing of products used in energy generation. In addition, we have custom product engineering capabilities that allow us to design specific products for unique applications, typically involving high temperatures.

Electronics Markets

Printed Circuit Board Assembly. We currently sell thermal processing systems used in the solder reflow and curing stages of printed circuit board assembly. Our printed circuit board assembly products are used primarily in the advanced high-density segments of the market, which utilize surface mount technology.

Our Pyramax family of convection reflow systems is designed on a single platform to be rapidly configurable, which is intended to reduce the product build cycle and allow us to meet customer demands for shorter delivery lead times. We believe Pyramax products offer our customers reduced capital cost, lower nitrogen consumption and reduced scheduled maintenance cycles.

Pyramax provides increased process flexibility due to its ability to process printed circuit boards up to 24 inches wide. Rated up to 400°C, these products are designed to be capable of operating in air or nitrogen atmospheres and to have increased convection flow for greater performance and lead free processes. Pyramax utilizes impingement technology to transfer heat to the substrate. These systems are offered in 7-zone and

10-zone heated lengths and are capable of processing lead free solder. They generally range in price from $40,000 to $150,000.

The market need for lead free solder reflow presents a unique problem by raising the process temperature critically close to the destruct temperature of the components that are being attached. Pyramax’s unique closed loop convection control is designed to provide a repeatable tight temperature window optimized for lead free solder reflow.

The solder reflow process requires the thermal processing system to manage flux residues eliminated during the processing of the printed circuit boards. Pyramax thermal processing systems are equipped with a patented flux management system structured to isolate the flux outside the main process chamber, thereby helping to maintain the integrity of the atmosphere and facilitate easy disposal.

Wafer Level and Die Level Semiconductor Packaging. We sell several systems for the thermal processes used in advanced semiconductor packaging.

Flip chip reflow provides the physical and electronic bond of the semiconductor device to its package. The Paragon and Pyramax families of convection reflow systems, utilizing our closed loop convection technology, rate at up to 400°C and operate in air or nitrogen atmospheres. These products utilize impingement technology to transfer heat to the substrate. Using thermal power arrays of five-kilowatt heaters, it can process substrates in dual track configurations, thereby enabling our customers to double production without increasing the machine’s footprint. These products are available in three models based on the heated lengths of thermal processing chambers. Heated length is based on the required production rate and loading requirements. The products generally range in price from $70,000 to $180,000.

Our TCAS series of continuous belt thermal processing systems is rated up to 800°C and is designed for wafer bump reflow. It can operate in a variety of controlled atmospheres including hydrogen, using patented gas barrier technology designed to achieve a safe and high purity hydrogen atmosphere. Our TCAS systems generally range in price from $300,000 to $1.2 million for a fully integrated 300mm system.

We offer fully integrated systems for flux coating and reflow of 200mm and 300mm wafers. The 300mm systems are designed to be fully compliant with I300i protocol and with SEMI S2 and S8 standards. These integrated systems include commercial robotics with FOUP handling, fluxing stations, reflow soldering systems and generally range in price from $500,000 to $1.2 million.

Alternative Energy Markets

The processing of advanced materials used in non-fossil fuel power generation applications is a significant target market. The rising cost of fossil fuels and environmental concerns have increased demand for power generation without the use of fossil fuels. For power generation applications, we serve the solar cell, fuel cell and nuclear fuel markets. We support our worldwide energy customers through our global sales and service network.

Solar Cells. We offer continuous furnaces for solar cell manufacturing. Processes for this application include diffusion, anti-reflective coatings and thick film silver contact firing. Our Quartz TQ Series muffle furnaces are used for phosphorous diffusion. Our Atmosphere Pressure Chemical Vapor Deposition furnaces are used in the deposition of anti-reflective coatings.

Customers

Many of our principal customers are large-volume global manufacturers that use our products in multiple facilities worldwide. Our top revenue generating customers in 2007 included Long Manufacturing , BP Solar, IBM, Suzhou Kaifa, Solectron, Nanosolar, Westinghouse, Guanjie, Intel, ASE, Motorola, Inner Mongolia Tendering, Transcend Information, Powertech Technologies, Compal Kunshan and M-Flex. In 2007, no customer accounted for more than 10% of net sales.

Sales, Marketing and Support

We market and sell our products primarily through our direct sales force and independent sales representatives throughout the world. Our sales and marketing team is responsible for evaluating the marketplace, generating leads and creating sales programs and literature. Our on-site direct service organization and our independent sales representatives provide ongoing support to customers using our products. These services include implementing continuous improvement tools related both to the cost of our products and to their technical performance. Our strong global support infrastructure allows us to market future sales within our current customer base and contributes to our competitive position. Our management and sales teams participate in periodic trade conventions, through which we market our products to potential customers.

Research, Development and Engineering

Our research, development and engineering efforts are directed toward enhancing existing products and developing our next generation of products. Research, development and engineering expense in 2007 was focused on the development of new products and improved furnace applications for thermal solutions for energy generation application processes; the expansion of our Pyramax solder reflow platform with the completion of the mid-sized Pyramax 100 offerings, which was developed jointly by BTU engineers in China and the U.S.A. The AtmoPlas development team is doing basic research on a different heating technology using microwave to create plasma. Our research, development and engineering costs for the years ended December 31, 2007, 2006 and 2005 can be found on our Consolidated Statements of Operations, contained herein.

We have a license and joint development agreement with Boston University focused on optimizing processes and materials used to manufacture solid oxide fuel cells (SOFCs). This program targets challenges that affect planar SOFC manufacturing costs, such as one-step co-firing, lower sintering temperatures and faster binder removal. We believe that this process development program, if successful, will help drive our thermal processing systems solutions for the SOFC market.

Close working relationships between our key customers and our product engineering teams enable us to incorporate our customers’ feedback and needs into our product development efforts. We have integrated our product design, manufacturing, engineering and after sales support documentation in support of the new product introduction process and lowered research, development and engineering costs.

Manufacturing and Suppliers

Our principal manufacturing operations consist of final assembly, systems integration and testing at our facilities in North Billerica, Massachusetts and Shanghai, China. We outsource the manufacture of many of our subsystems to a number of key suppliers and maintain close relationships with them while also maintaining qualified alternative suppliers and to maintain a cost down focus in the event we exceed the capacity of our key suppliers or otherwise lose access to these suppliers. In 2004, we established an engineering and manufacturing facility in Shanghai, China for our printed circuit board products as well as local sourcing of materials.

In the past two years, we have substantially improved our global supply chain and reduced our material costs. These efforts have resulted in a major improvement in gross margins in the Pyramax product line. We have upgraded and reorganized our operations organization in the U.S. In addition, we have broadened our supply base in China. We have leveraged our presence there to widen the base of suppliers for the Pyramax family of reflow soldering equipment.

Continuous improvement in the supply chain is a key strategic imperative. We have established a global sourcing organization, based in China, to further develop high quality, cost effective suppliers throughout the world.

We continue to invest in software and capital equipment related to our information technology infrastructure and customer support. We have made a major investment in and are in the process of installing a new business operations and management system in Shanghai and at the Company’s headquarters in Billerica, MA.

We have outsourced the manufacture of most of our significant component systems thereby reducing cycle time and increasing our inventory turnover. We seek to adhere closely to the principles of total quality management and have been ISO 9001 certified since 1998 and converted to ISO 9000:2000 in October 2003. Our customers, suppliers and employees are strongly encouraged to provide feedback and suggestions for improvements in products and services.

Intellectual Property

We seek to protect our intellectual property by filing patents on proprietary features of our advanced thermal processing systems and by challenging third parties that we believe infringe on our patents. We also protect our intellectual property rights with nondisclosure and confidentiality agreements with employees, consultants and key customers and with our trademarks, trade secrets and copyrights. As a global supplier of equipment, we recognize that the laws of certain foreign countries may not protect our intellectual property to the same extent as the laws of the U.S.

We license software programs from third party developers and incorporate them into our products. Generally, these agreements grant us non-exclusive licenses to use the software and terminate only upon a material breach by us. We believe that such licenses are generally available on commercial terms from a number of licensors.

Backlog

Backlog as of December 31, 2007, was $11.5 million, compared to $8.9 million as of December 31, 2006. As of December 31, 2007, we expected to ship our year-end backlog within 40 weeks. Most of our backlog for solder reflow systems is expected to be shipped within 3 to 8 weeks. The backlog of our custom systems is expected to be shipped within 12 to 40 weeks. We include in backlog only those orders for which the customer has issued a purchase order. Due to possible changes in delivery schedules, lead time variations and order cancellations, our backlog at any particular date is not necessarily representative of sales for any subsequent period.

Competition

Several companies compete with us in selling thermal processing systems. Although price is a factor in buying decisions, we believe that technological leadership, process capability, throughput, environmental safeguards, uptime, mean time-to-repair, cost of ownership and after-sale support have become increasingly important factors. We compete primarily on the basis of these criteria, rather than on the basis of price.

Our principal competitors for printed circuit board assembly equipment and advanced semiconductor packaging vary by product application. Our principal competitors for solder reflow systems are Vitronics-Soltec, Heller, Furakawa, ERSA, Rehm and Electrovert. Our principal competitors for advanced semiconductor packaging are Sikama, SEMIgear and Heller. Our systems for the energy generation markets and other applications compete primarily against products offered by Despatch, SierraTherm, Centrotherm and Harper. We also face competition from emerging low cost Asian manufacturers and other established European manufacturers.

Employees

As of December 31, 2007, we had 351 employees, of whom 69 are engaged in sales, marketing and service, 40 in research, development and engineering, 39 in finance and administration and 203 in operations. Of these 351 employees, 188 reside outside of the U.S. None of our employees are represented by a collective bargaining agreement, and we believe that we have satisfactory relations with our employees.

Environmental

One of our core values is protecting the environment in which we operate and the environment in which our equipment operates. Compliance with laws and regulations regarding the discharge of materials into the environment, or otherwise relating to the protection of the environment, has not had any material effects on our capital expenditures, earnings or competitive position. We do not anticipate any material capital expenditures for environmental control facilities in 2008.

ITEM 1A. RISK

FACTORS

Risks Relating to Our Business

We are subject to cyclical downturns in the electronics and semiconductor industries.

Our business depends predominantly on the capital expenditures of electronics semiconductor manufacturers, which in turn depend on current and anticipated market demand for printed circuit boards and integrated circuits and the products that use them. The electronics semiconductor industries have historically been cyclical and have experienced periodic downturns that have had a material adverse effect on the demand for electronic semiconductor equipment, including equipment that we manufacture and market. During periods of declining demand, we may have difficulty aligning our costs with prevailing market conditions, as well as motivating and retaining key employees. In particular, our inventory levels during periods of reduced demand may be higher than optimal, and we may be required to make inventory valuation adjustments in future periods. During periods of rapid growth, on the other hand, we may fail to acquire and/or develop sufficient manufacturing capacity to meet customer demand, and we may fail to hire and assimilate a sufficient number of qualified people. Our business may be adversely affected if we fail to respond to rapidly changing industry cycles in a timely and effective manner.

We have shifted a significant and growing portion of our production capacity to a manufacturing facility in Shanghai, China. We may encounter manufacturing problems associated with managing these operations.

In 2004, we began manufacturing and material sourcing operations in a facility in Shanghai, China. The volume of our products produced in China is now approximately one half of our total production. The successful

operation of our facility in China is important to our ability to remain profitable and competitive. We may encounter difficulty with the management, technical and administrative organization requirements of doing business in China. If we are not successful in managing our operation in China, our business and profitability will be adversely affected.

In the past three years, we have substantially improved our global supply chain and reduced our material costs. Failure to maintain these cost reductions would negatively affect our profit margins.

In the last three years, we have substantially improved our global supply chain and reduced our material costs. These efforts have resulted in a major improvement in gross margins in our Pyramax product line as well as reduced costs for our solar metallization line. While continuous improvement in the supply chain is a key strategic imperative, we may not be successful in achieving our cost reduction goals, in which case further increases in our gross margins would not be achieved. If our costs increase, our gross margin gains will erode. This could be caused by foreign exchange trends, supplier cost increases, increase in fuel costs and other factors.

Sales of our products to the energy generation markets are subject to substantial risks.

Solar Energy. The solar energy sector is partially dependent upon continuation of governmental subsidies that may not continue and the supply of materials that may be constrained. A decline in these subsidies would reduce our ability to grow our business in this market segment. The solar energy sector also depends on the availability of raw materials such as silicon. Limits in the supply of these raw materials will constrain growth in this sector and, therefore, limit our prospects for increasing sales in this area.

Nuclear Energy. The market for nuclear fuel pellets used in power generation is dependent upon further growth in nuclear power production. Consequently, without growth in the production of nuclear power, our opportunities to grow in this area will be limited. In addition, we may need export licenses to supply this type of equipment to several countries. Failure to maintain such licenses or obtain new required licenses will limit our ability to expand our revenue from this market.

Fuel Cells. The developing fuel cell sector of the energy market is in an early stage of product development, without any guarantees of commercial success. There is considerable risk that this technology may not succeed and our sales to this market may not develop. Given our limited experience in this segment of the energy generation market, we may encounter problems growing this part of our business.

Failure to realize the full value of the R.T.C. and AtmoPlas acquisitions could negatively affect the Company’s profitability.

Success of the acquired R.T.C. products in the Solar Energy market is only partially dependent on the abilities of the Company. These Infrared furnace applications are dependent on the same market risks identified above under Solar Energy. The AtmoPlas acquisition represents a major development opportunity for the Company, yet at substantial risk. Should the Company fail to commercially actualize the potential developmental products and process applications, substantial costs would be incurred by the Company without benefit.

If we are unable to increase sales and reduce costs, our profitability may be affected negatively.

We generated net income of $1.9 million in 2007 versus income of $9.2 million in 2006. Our year to year net income decrease was mainly due to a combination of a decrease in net sales and an increase in SG&A and RD&E expenses. We attribute a large portion of the increase in SG&A and RD&E expenses primarily to additional costs resulting from investments in the alternative energy business. In 2008, the Company plans to increase its SG&A and RD&E spending in support of the alternative energy business. We may not experience the projected growth in the alternative energy business to offset this additional investment.

Our future success will depend on our ability to effectively develop and market our products against those of our competitors.

The industry in which we compete is extremely competitive. Some of our competitors have substantially greater financial, engineering, manufacturing and customer support capabilities and offer more extensive product offerings. If customers prefer products offered by our competitors, we will have difficulty maintaining or increasing our revenue. Our principal competitors for solder reflow systems are Vitronics-Soltec, Heller, Furakawa, ERSA, Rehm and Electrovert. Our principal competitors for advanced semiconductor packaging are Sikama, SEMIgear and Heller. Our systems for the energy generation markets and other applications compete primarily against products offered by SierraTherm, Centrotherm and Harper. We expect our competitors to continue to improve the design and performance of their current products and to introduce new products with improved performance capabilities. Our failure to introduce new products in a timely manner, or the introduction by our competitors of products with perceived or actual advantages, could result in reduced sales of, or lower margins on, our products. In future years, we expect to face increased competition based on price, particularly from companies in Asia. If we are unable to reduce the costs of our products or introduce new lower cost products, we may lose sales to these competitors.

Our international sales and operations are subject to the economic, political, legal and business environments of the countries in which we do business, and our failure to operate successfully or adapt to changes in these environments could cause our international sales and operations to be limited or disrupted.

Our international sales accounted for 82.4% of our consolidated revenue for 2007. We expect to continue to generate a significant percentage of our revenue outside the United States for the foreseeable future. In addition, we have direct investments in a number of subsidiaries outside of the U.S., primarily in Asia and Europe. Our international operations could be limited or disrupted, and the value of our direct investments may be diminished, by any of the following:

•

fluctuations in currency exchange rates;

•

the imposition of governmental controls;

•

import and export license requirements;

•

political instability;

•

difficulties enforcing contractual and intellectual property rights;

•

terrorist activities and armed conflict;

•

restrictions on direct investments by foreign entities and trade restrictions;

•

changes in tax laws and tariffs;

•

costs and difficulties in staffing and managing international operations; and

•

longer customer payment cycles.

Additionally, we are subject to the Foreign Corrupt Practices Act, which may place us at a competitive disadvantage to foreign companies that are not subject to similar regulations.

We conduct only a small portion of our sales in currencies other than the U.S. dollar. We recognize foreign currency gains or losses arising from our operations in the period in which we incur those gains or losses. As a result, currency fluctuations among the U.S. dollar and the currencies in which we do business have caused foreign currency transaction gains and losses in the past and will likely do so in the future. Because of the number of currencies involved, the variability of currency exposures and the potential volatility of currency exchange rates, we may suffer foreign currency transaction losses in the future due to the effect of exchange rate fluctuations.

Over the past few years, a majority of our revenue is generated from sales in the Asia Pacific region. Our operations are particularly vulnerable to instability in this region and competition from organizations based in this region.

During 2007, 56.1% of our revenue was generated from sales in the Asia Pacific region. Political or economic instability in any of the major Asia Pacific economies may adversely impact the demand for capital equipment, including equipment of the type we manufacture and market. In addition, we face competition from a number of suppliers based in the Asia Pacific region that have certain advantages over U.S. suppliers, including us. These advantages include, among other things, lower operating and regulatory costs, proximity to customers, favorable tariffs and affiliation with significantly larger organizations. In addition, changes in the amount or price of electronics or solar cells produced in the Asia Pacific region could negatively impact spending by our customers.

The cost of public company regulatory compliance in the United States places the Company at a competitive disadvantage in its primary geographical market.

The Company is incurring and will continue to incur substantial increased internal staffing, external consulting, tax and audit costs to comply with governmental regulations imposed on public companies in the United States. The Company’s primary geographical growth market of opportunity is Asia for both the Company’s Electronics and Alternative Energy products. The Company is competitively disadvantaged as our Asian competitors are not subject to these same regulatory costs.

In China our new business systems to manage our operations are still being developed. If they are not developed and implemented, it could have a material adverse effect on our business.

On January 1, 2007, we implemented new enterprise resource planning and material resource planning systems at our Shanghai manufacturing operations. In 2008, our Shanghai personnel will be expanding their use of the system. As our Chinese operations grow, the risks increase that we will not fully utilize the advanced material resource planning system, which could disrupt our business.

In the U.S. our new business systems to manage our operation were activated on January 1, 2008. These systems are still being developed. If they are not developed and implemented effectively, it could have a material adverse effect on our business.

Over the past year, we have invested heavily to insure a smooth startup of the new operating system. However, much work lays ahead, and the risks associated with not fully utilizing our advanced enterprise resource planning and material resource planning systems could disrupt our business.

The Company may be subject to some portion of an environmental clean-up under Superfund legislation.

The Company is an equipment manufacturer that has some solid waste. Due to the fact that the Company utilized a waste disposal firm that disposed its solid waste at a site that the EPA has designated as a Superfund site, the Company has been named by the EPA as one of the entities potentially responsible for clean-up operations. It is not known at this time what the costs of these activities might be or the Company’s share, if any, thereof.

Being an equipment manufacturer, the Company only deals with extremely small amounts of chemicals. The Company’s chemical waste were disposed under a controlled process that meets strict EPA approved disposal procedures and were not disposed at the Superfund site.

If we fail to maintain positive relationships with key personnel, we may be unable to successfully grow our business.

Our future operating results depend substantially upon the continued service of our key personnel, some of whom are not bound by employment or non-competition agreements. Our future operating results also depend in

significant part upon our ability to attract and retain qualified management, manufacturing, technical, engineering, marketing, sales and support personnel. Competition for qualified personnel, particularly those with technical skills, is intense, and we may fail to attract and retain qualified personnel. Our business, financial condition and results of operations could be materially adversely affected by the loss of any of our key employees, by the failure of any key employee to perform in his or her current position, or by our inability to attract and retain skilled employees.

The income tax percentage on the Company’s consolidated income before taxes is subject to variables beyond our control.

The Company’s net income and cash flow can be adversely affected by innumerable conditions affecting income taxes which are outside the Company’s scope of authority to control. To name but a few of the potential uncontrollable circumstances that could affect the consolidated tax rate:

•

The Company sells and operates globally with manufacturing in both the United States and China. Disagreements could occur on the jurisdiction of income and taxation among different country governmental tax authorities. Potential area of disputes could include transfer pricing values, inter-company cross charges and inter-company balances.

•

The Company is presently benefiting from a partial “tax holiday” in its Shanghai manufacturing subsidiary. Recently the Chinese government tax authorities announced the passage of legislation to impose an equalization of income tax rates for both domestic and foreign companies at a rate of 25%. This new law supersedes and overrides the Company’s tax holiday agreements. The applicability of this new uniform income tax rate law will have an adverse effect on the Company’s net income and cash flow.

•

The Company is subject to a China withholding tax on certain non-tangible soft charges made under its transfer pricing agreements. The interpretation of what charges are subject to the tax and when the liability for the tax occurs has varied and could change in the future.

•

In the United States, new tax disclosure regulations, unfavorable interpretations and unforeseen enforcements by the government tax authorities of various provisions of the federal and state tax codes, could have an unfavorable impact on the amount and timing of the Company’s tax provision and cash flow.

Failure of critical suppliers to deliver sufficient quantities of parts in a timely and cost-effective manner would adversely impact our operations.

Although we use numerous vendors to supply components for the manufacture of our products, not all are qualified suppliers for all of our parts. Some key parts may only be available from a single supplier. Accordingly, we may experience problems in obtaining adequate and reliable quantities of various components. In addition, suppliers may cease manufacturing certain components that are difficult to replace without significant reengineering of our products. Our results of operations will be materially adversely impacted if we are unable to obtain adequate supplies of components in a timely and cost effective manner.

The occurrence of natural disasters in the Asia Pacific region may adversely impact our operations and sales.

We have an expanding engineering and manufacturing facility in China, and the majority of our sales are made to destinations in the Asia Pacific region. This region is known for being vulnerable to natural disasters and other risks, such as earthquakes, floods and avian (bird) flu, which at times have disrupted the local economies. A significant earthquake or health crisis could materially affect our operating results. We are not insured for most losses and business interruptions of this kind, and we do not have redundant, multiple site capacity in the event of a natural disaster. In the event of such a disaster, our business would suffer.

Provisions in our organizational documents could prevent or frustrate attempts by stockholders to replace our current management and could make acquisitions more difficult.

Our certificate of incorporation and by-laws contain provisions that could make it more difficult for a third party to acquire us without the consent of our board of directors. Our certificate of incorporation provides that our stockholders may not take action by written consent. This provision may have the effect of preventing or hindering attempts by our stockholders to replace our current management. Furthermore, Delaware law prohibits a corporation from engaging in a business combination with any holder of 15% or more of its capital stock until the holder has held the stock for three years unless, among other possibilities, the corporation’s board of directors approves the transaction. Our board of directors may use this provision to prevent changes in our management. Also, our board of directors may adopt additional anti-takeover measures in the future.

Our officers and directors may be able to block proposals for a change in control.

Paul J. van der Wansem, our chairman and chief executive officer, beneficially owns approximately 16.0% of our outstanding common stock as of December 31, 2007. Due to this concentration of ownership, Mr. van der Wansem may be able to prevail on all matters requiring a stockholder vote, including:

•

the election of directors;

•

the amendment of our organizational documents; or

•

the approval of a merger, sale of assets, or other major corporate transaction.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

BTU International, founded in 1950 and headquartered in Billerica, Massachusetts, is a supplier of advanced thermal processing equipment to the electronics manufacturing and energy generation markets. We manufacture reflow furnaces for printed circuit board assembly as well as semiconductor wafer-level and die-level packaging equipment. In addition, we participate in the fast growing alternative energy market, for which we provide thermal process equipment for the manufacturing of solar cells, fuel cells and nuclear fuels.

In 2004, we began manufacturing and material sourcing operations in a leased facility in Shanghai, China. During 2005, we began construction of additional leased facilities in Shanghai, which became fully operational in the second quarter of 2006. These additional facilities were needed for further expansion into the Asia Pacific region. In addition, we expanded our product development capability to China, creating a global engineering team. This team has developed and commercially introduced our latest Pyramax product and continues to collaborate with our U.S. headquarters on additional product initiatives.

In the past few years, we have substantially improved our U.S. and global supply chain and reduced our materials costs. These efforts have resulted in a major improvement in gross margins primarily in our Pyramax product line, manufactured in both our U.S. and China factories.

Critical Accounting Policies

The following is a discussion of those accounting policies that we deem to be “critical” — that is, they are important to the portrayal of our financial condition and results of operations, and they reflect management’s reliance on estimates regarding matters that are inherently uncertain.

Revenue Recognition. We recognize revenue in accordance with the Securities and Exchange Commission (SEC) Staff Accounting Bulletin (SAB) No. 101, “Revenue Recognition in Financial Statements” as updated by SAB No. 104, “Revenue Recognition.” Under these guidelines, we recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services rendered, the price is fixed or determinable and payment is reasonably assured. Under these requirements, we recognize revenue upon acceptance when the terms of sale include customer acceptance provisions and compliance with those provisions has not been previously demonstrated. Furthermore, we recognize revenue upon completion of installation for products that require installation for which the installation is essential to functionality or is not inconsequential or perfunctory. Revenue for products sold where installation is not essential to functionality and is deemed inconsequential or perfunctory are recognized upon shipment with estimated installation and warranty costs accrued.

Applying the requirements of SAB No. 101 and SAB No. 104 to future sales arrangements used in our equipment sales may result in the deferral of the revenue for some equipment sales.

We also have certain sales transactions for products which are not completed within the normal operating cycle of the business. It is our policy to account for these transactions using the percentage of completion method for revenue recognition purposes when all of the following criteria exist: (1) we received the purchase order or entered into a legally binding contract, (2) the customer is credit worthy and collection is probable or customer prepayments are required at product completion milestones or specific dates, (3) the sales value of the product to be delivered is significant in amount when compared to our other products, and (4) the costs can be reasonably estimated, there is no major technological uncertainty and the total engineering, material procurement, product assembly and test cycle time extend over a period of six months or longer.

Under the percentage of completion method, revenue and gross margins to date are recognized based upon the ratio of costs incurred to date compared to the latest estimate of total costs to complete the product as a percentage of the total contract revenue for the product. Revisions in costs and gross margin percentage estimates are reflected in the period in which the facts causing the revision become known. Provisions for total estimated losses on uncompleted contracts, if any, are made in the period in which such losses are determined.

Inventory Valuation. Our inventories consist of material, labor and manufacturing overhead costs. We determine the cost of inventory based on the first-in, first-out method. We regularly review the quantity of inventories on hand and compare these quantities to the expected usage of each applicable product or product line. Our inventories are adjusted in value to the lower of costs and/or net realizable value. Since the value of our inventories depends in part on our estimates of each product’s net realizable value, adjustments may be needed to reflect changes in valuation. Any adjustments we are required to make to lower the value of the inventories are recorded as a charge to cost of sales.

Stock Based Compensation. Effective January 1, 2006, we adopted the provisions of the SFAS No. 123R, Share-Based Payment (SFAS No. 123R). Under SFAS No. 123(R), we are required to record compensation cost for all share-based payments granted after the date of adoption based on the grant date fair value, estimated in accordance with the provisions of SFAS No. 123R, and for the unvested portion of all share-based payments previously granted that remain outstanding based on the grant date fair value, estimated in accordance with the original provisions of SFAS No. 123. We expense share-based compensation under the straight-line method.

The choice of a valuation technique, and the approach utilized to develop the underlying assumptions for that technique, involve significant judgments. These judgments reflect management’s assessment of the most accurate method of valuing the stock options we issue, based on our historical experience, knowledge of current conditions and beliefs of what could occur in the future given available information. Our judgments could change over time as additional information becomes available to us, or the facts underlying our assumptions change over time, and any change in our judgments could have a material effect on our financial statements. We believe that our estimates incorporate all relevant information and represent a reasonable approximation in light of the difficulties involved in valuing non-traded stock options.

RESULTS OF OPERATIONS

The following table sets forth the percentage of net sales of certain items in our consolidated statements of operations for the periods indicated.

FISCAL YEAR ENDED DECEMBER 31, 2007 AS COMPARED TO FISCAL YEAR ENDED DECEMBER 31, 2006

Net Sales. In 2007, net sales declined quarter to quarter for the first half of 2007 and increased in each of the quarters in the second half of 2007. Overall for the year 2007, net sales decreased by $14.6 million or 18.6% vs. 2006, from $78.3 million in 2006 to $63.7 million in 2007. For 2007 the electronics assembly business was down by 30 percent compared to 2006 while there was strong growth in our alternative energy business in 2007. In solar photovoltaics for 2007, the Company was able to double our revenues for the year and bookings increased by more than two and a half times.

As compared to 2006, the percentage of net sales attributable to our customers in the United States stayed the same in 2007, net sales attributable to our customers in Europe decreased by 5%, net sales attributable to our Asia Pacific customers increased by 7% and net sales attributable to our customers in the other Americas decreased by 1%.

Gross Profit. The increase in the gross profit percentage to 43.0% for 2007 versus 40.5% 2006 was principally the result of a favorable product mix, lower material costs in our U.S. operations and improvements in our China assembly and China material sourcing for global operations.

Selling, General and Administrative. SG&A costs increased by 10.9% from $17.1 million to $19.0 million in 2007 versus 2006. The increase in selling, general and administrative expenses in 2007 versus 2006 is reflective of the Company’s expansion in the alternative energy markets and the continuing increased costs associated with government regulations on United States public companies with global operations. The increased selling, general and administrative costs in 2007 versus 2006 are due to added sales, service and marketing expenses for our alternative energy products and added administrative costs associated with the expensing of stock options, Sarbanes-Oxley compliance, tax consulting and legal costs.

Research, Development and Engineering. In 2007 the Company increased its spending on RD&E versus 2006 primarily for our development efforts towards new products for our alternative energy markets and enhancements to our electronics market products.

Operating Income. The decrease in operating income was primarily the result of decreased revenues and partially due to increases in SG&A and RD&E expenses, which were partially offset by improved gross margin percentages.

Interest Income (Expense), Net. The change in net interest income/expense decreased from $307,000 of income in 2007 to $105,000 of income in 2006.

Foreign Exchange (Loss). Foreign Exchange loss increased from a $232,000 loss in 2006 to a $478,000 loss in 2007 primarily due to the continued reduction in the valuation of the US dollar against the Chinese RMB.

Income Taxes. In 2007 the government of China approved a tax equalization law for foreign and domestic companies that impacts BTU. 2007 is the first year that the Company is taxable in China. This event plus the recording of China withholding taxes on royalty charges are the primary elements of the 2007 tax provision. In the USA, the Company has federal and state net operating loss carry forwards of approximately $6 million. The Company has recorded a full valuation allowance to offset the deferred tax asset arising as a result of these loss carry forwards because of uncertainty surrounding realization. Our statutory federal income tax rate is 34.0%.

Earnings per Share. Note that the total year diluted earnings per share (EPS) in this 10-K rounds to $0.20 vs. the Company’s Press Release of February 26, 2008 which reported total year diluted EPS of $0.21. The reason for the difference was an adjustment in the 123R calculation which increased the diluted shares by 59,961 shares. The impact is from $0.2054 to $0.2041 or $0.0013 adjustment. This adjustment had no impact on any quarter or on any year to date diluted EPS during 2007.

FISCAL YEAR ENDED DECEMBER 31, 2006 AS COMPARED TO FISCAL YEAR ENDED DECEMBER 31, 2005

Net Sales. Net sales increased 17.9% from $66.4 million in 2005 to $78.3 million in 2006. The primary 2006 increases in net sales were from the Company’s Surface Mount Technology and Solar markets.

The percentage of net sales attributable to our customers in the United States increased in 2006 by 1.2%, net sales attributable to our customers in Europe remained the same, net sales attributable to our Asia Pacific customers decreased by 4.0% and net sales attributable to our customers in the other Americas increased by 2.7%. Although the 2006 net sales dollars increased by over 9%, the decrease in the percentage of 2006 net sales to the Asia Pacific region reflects the decline in demand for our Surface Mount Technology products in this territory in the second half of 2006. The increase in net sales for the other Americas represents a continuing growth market with the primary increase in Brazil.

Gross Profit. Gross profit increased 33.2% from $23.8 million in 2005 to $31.7 million in 2006 and, as a percentage of net sales, increased from 35.9% in 2005 to 40.5% in 2006. The increase in gross profit as a percentage of sales for 2006 was primarily the result of significant cost reductions for the raw materials for the Company’s Pyramax products as well as other products and significant savings resulting from the Company’s expansion of its China manufacturing facilities.

Selling, General and Administrative. Selling, general and administrative costs increased 11.7% from $15.3 million in 2005 to $17.1 million in 2006, but as a percentage of net sales, decreased from 23.1% to 21.9%. The increase in costs in 2006 represents expenditures required to properly service our global customer base and support the added SG&A needs associated with the Sarbanes Oxley compliance requirements.

Research, Development and Engineering. Research, development and engineering costs increased 58.0% from $3.2 million in 2005 to $5.1 million in 2006, and as a percentage of net sales, increased from 4.8% in 2005 to 6.4% in 2006. In 2006, the Company shifted more of its development resources to focus on the opportunities presented by the alternative energy generation market. The Company’s investment in and continued development spending on the AtmoPlas technology, represents a commitment to future opportunities in the alternative energy arena.

Operating Income. The Company went from an operating income of $5.3 million in 2005 to an operating income of $9.5 million in 2006, and as a percentage, operating income increased from 8.0% of net sales in 2005 to an operating income of 12.2% of net sales in 2006.

Interest Income (Expense), Net. Net interest income/expense went from $563,000 of expense in 2005 to $120,000 of income in 2006 primarily as a result of interest expense from the Company’s increased mortgage on its facilities in Billerica, MA, offset by interest income earned on the cash generated by the Company and a secondary offering of stock.

Income Taxes. The Company recorded a tax expense of $189,000 in 2006. This amount is the result of the Company recording a current tax provision of $395,000 offset by the reversal of various deferred tax reserves of $206,000. The tax holiday we currently have in China combined with the utilization of net operating loss carryovers has allowed the Company to record a low effective tax rate. The Company’s statutory federal income tax rate is 34%.

LIQUIDITY AND CAPITAL RESOURCES

As of December 31, 2007, we had $25.1 million in cash and cash equivalents.

During 2007, we generated net cash of approximately $2.0 million from operating activities. This generation of cash was primarily the result of a net profit of $1.9 million, adding back depreciation and amortization of $1.5 million and a decrease in inventories of $1.1 million, offset by an increase in accounts receivable of $2.4 million.

On March 1, 2007, the Company entered into an amended revolving loan agreement with a bank that allows for unsecured aggregate borrowings, including letters of credit, up to a maximum of $15 million against a borrowing base of accounts receivable, inventory and fixed assets. The Company may elect to borrow at interest rates related to the bank’s prime rate or LIBOR. This loan agreement extends to December 31, 2010 and is subject to maintaining certain financial covenants, of which the Company is in full compliance. At December 31, 2007, the borrowing base would support the maximum borrowings of $15 million, and there were no borrowings outstanding under the loan agreement.

On March 30, 2006, we entered into a new mortgage note that is secured by our real property in Billerica, MA, in the amount of $10 million. The mortgage note requires monthly payments of $76,280, which includes interest calculated at the rate of 6.84% per annum. This mortgage note payable has a balloon payment of

$6.8 million due and payable at maturity on December 23, 2015. The mortgage note had an outstanding balance at December 31, 2007 of approximately $9.5 million.

We had no material commitments for capital expenditures as of December 31, 2007.

Our business forecasts project that our cash position, cash flow and our working capital line of credit will be sufficient to meet our corporate, operating and capital requirements through 2008.

RECENT ACCOUNTING PRONOUNCEMENTS

The Company adopted the provisions of the Financial Accounting Standards Board (the “FASB”) Interpretation No. 48 (FIN 48), “Accounting for Uncertainty in Income Taxes”, on January 1, 2007. As a result of the implementation of FIN 48, the Company made a comprehensive review of its portfolio of uncertain tax positions in accordance with recognition standards established by FIN 48. In this regard, an uncertain tax position represents the Company’s expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes. The Company believes that it has appropriate support for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for all open years based on an assessment of many factors, including past experience and interpretations of tax law applied to the facts of each matter. As a result of applying the provisions of FIN 48, there was no cumulative effect on retained earnings.

For the year ended December 31, 2007, there were no material changes to the total amount of unrecognized tax benefits. The Company does not expect any significant increases or decreases for uncertain tax positions during the next 12 months.

The Company files income tax returns in the U.S. and various states as well as several foreign jurisdictions. The tax years 2003 through 2006 remain open to examination by the tax jurisdictions to which we are subject.

The Company’s policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. There is no interest or penalties accrued at December 31, 2007. As a result of this review, the Company concluded that at this time there are no uncertain tax positions.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities-including an amendment of SFAS No. 115”. The new statement allows entities to choose, at specified election dates, to measure eligible financial assets and liabilities at fair value that are not otherwise required to be measured at fair value. If a Company elects the fair value option for an eligible item, changes in that item’s fair value in subsequent reporting periods must be recognized in current earnings. SFAS No. 159 will be effective for fiscal years beginning after November 15, 2007. The Company does not believe the adoption of SFAS No. 159 will have a material impact on its financial condition or results of operations.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”) which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. On February 12, 2008, the FASB issued FASB Staff Position (“FSP”) SFAS No. 157-2, Effective Date of SFAS No. 157. The FSP amends SFAS 157, to delay the effective date of SFAS 157 for all non-financial assets and non-financial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (that is, at least annually) to fiscal years beginning after November 15, 2008. The Company is currently evaluating the effect that the implementation of SFAS 157 will have on its financial position, results of operations and cash flows.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), “Business Combinations” (SFAS 141R). SFAS 141R will significantly change the accounting for business combinations in a number of areas including the treatment of contingent consideration, contingencies, acquisition costs, in-process research and development, and restructuring costs. In addition, under SFAS 141R, changes in deferred tax asset valuation allowances and acquired income tax uncertainties in a business combination after the measurement period will impact income taxes. SFAS 141R is effective for fiscal years beginning after December 15, 2008, which is the Company’s fiscal year beginning January 1, 2009, and will impact the accounting for any business combinations entered into after the effective date.

In December 2007, the FASB issued SFAS No. 160, “Non-controlling Interests in Consolidated Financial Statements, an amendment of Accounting Research Bulletin (ARB) No. 51,” which changes the accounting and reporting for minority interests. Minority interests will be re-characterized as non-controlling interests and will be reported as a component of equity separate from the parent’s equity, and purchases or sales of equity interests that do not result in a change in control will be accounted for as equity transactions. In addition, net income attributable to the non-controlling interest will be included in consolidated net income on the face of the income statement and, upon a loss of control, the interest sold, as well as any interest retained, will be recorded at fair value with any gain or loss recognized in earnings. SFAS No. 160 will apply prospectively, except for the presentation and disclosure requirements, which will apply retrospectively. SFAS No. 160 is effective for periods beginning on or after December 15, 2008 and will impact the accounting for non-controlling interests after the effective date.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISK DISCLOSURE

Our primary market risk exposure is in the area of foreign currency exchange rate risk as we are exposed to currency exchange rate fluctuations as they pertain primarily to accounts receivable in U.S. dollars on our China subsidiary’s books.

As of December 31, 2007, all of our long-term debt and capital lease obligations are fixed rate financial instruments. Therefore we are not exposed to interest rate risk resulting from variable interest rate of our debt.

During the eight quarters of 2006 and 2007, net sales were at a high of $22.5 million in Q2 2006 and decreased for each of the succeeding four quarters through the second quarter of 2007 to a low of $13.8 million before rebounding in the last two quarters of 2007. These sales increases in the last half of 2007 were primarily in Energy Generation products.

Gross profit as a percentage of net sales during the last eight quarters began at a low of 38.4% and continuously increased to a peak of 43.4% in the third quarter of 2007. The continuous improvement in gross profit percentage for the quarters was primarily the result of product mix cost reductions from the Company’s global sourcing program for raw materials and significant labor and overhead savings resulting from the Company’s expansion of its China manufacturing facilities.

Selling, general and administrative costs during the last eight quarters in 2006 and 2007 increased from a low of $3.9 million to a high of $5.2 million. The increase in costs represents the staffing and expense adjustments required to properly support and service our customers globally with our expanded initiatives in our alternative energy markets and our continued enhancements in our electronics markets. In addition, the Company has seen increases in internal and external administrative expenses necessary to comply with the regulation burden of being a USA public company.

Research, development and engineering costs for the last eight quarters have increased from a low of $0.9 million to a high of $1.5 million. The major increases are related to the Company’s continuing development of products for the Alternative Energy market. In June of 2006, the Company acquired AtmoPlas, which is an R&D development concentrating on thermal processing using a microwave plasma technology. The development costs of AtmoPlas are included in the RD&E expenses.

Income from operations in the last eight quarters increased and decreased quarter to quarter as the net sales increased or decreased quarter to quarter.

The provision for income tax in the fourth quarter of 2007 reflects a higher than forecasted tax rate for one of the Company’s overseas subsidiaries.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

BTU International, Inc. and its wholly owned subsidiaries (the Company) are primarily engaged in the design, manufacture, sale, and service of thermal processing systems, which are used as capital equipment in various manufacturing processes, primarily in the electronics and alternate energy industries.

PRINCIPLES OF CONSOLIDATION AND THE USE OF ESTIMATES

The accompanying consolidated financial statements include the accounts of the Company. All material inter-company balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. The primary estimates used in the consolidated financial statements include percent complete revenue, inventory valuation, allowance for doubtful accounts and warranty reserves.

CASH AND CASH EQUIVALENTS

The Company has classified certain liquid financial instruments, with original maturities of three months or less, as cash equivalents.

ACCOUNTS RECEIVABLE

Accounts receivable are stated at the amount management expects to collect from outstanding balances. An allowance for doubtful accounts is provided for those accounts receivable considered to be uncollectible based upon historical experience and management’s evaluation of outstanding accounts receivable at the end of the year. Bad debts are written off against the allowance when identified. Bad debt expense was $(23,000), $(164,000) and $167,000 for 2007, 2006 and 2005, respectively.

INVENTORIES

Inventories consist of material, labor and manufacturing overhead and are valued at the lower of cost or net realizable value. Cost is determined by the first-in, first-out (FIFO) method for all inventories.

Inventories consist of the following (in thousands):


	Years Ended December 31,
	2007		2006
Raw materials and manufactured components	$	11,439	$	11,276
Work-in-process		3,718		3,672
Finished goods		1,734		2,409

	$	16,891	$	17,357

The Company periodically reviews quantities of inventory on hand and compares these amounts to expected usage of each particular product or product line. The Company also records, as a charge to cost of goods sold, any amounts required to reduce the carrying value of the finished goods inventory to net realizable value. The

BTU INTERNATIONAL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Company recorded inventory provisions of $(299,000), $(69,000), and $375,000 in 2007, 2006, and 2005, respectively. The provisions recorded are net of sold inventory that had previously been reserved in the amounts of $388,000, $250,000, and $215,000 for the years ending 2007, 2006, and 2005, respectively.

PROPERTY, PLANT AND EQUIPMENT

The Company provides for depreciation using the straight-line method over the assets’ useful lives. The estimated useful lives for depreciation purposes are as follows:


Buildings and improvements		8-25 years
Machinery and equipment		2-8 years
Furniture and fixtures		3-8 years
Leasehold improvements		3 years

Depreciation expense was approximately $974,000, $783,000 and $775,000 for the years ended December 31, 2007, 2006 and 2005, respectively.

Maintenance and repairs are charged to operations as incurred. When equipment and improvements are sold or otherwise disposed of, the asset cost and accumulated depreciation are removed from the accounts, and the resulting gain or loss, if any, is included in the results of operations.

The Company evaluates long-lived assets such as intangible assets and property, plant and equipment under SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (SFAS 144). This statement requires that long-lived asset and certain identifiable intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. No impairments of intangible assets or property, plant and equipment have been identified during the years ended December 31, 2007 and December 31, 2006.

OTHER ASSETS

Other assets consist of the following (in thousands):


	2007		2006
Deferred financing costs, net of amortization	$	99	$	66
Deferred tax assets		206		206
Intellectual Property, net of amortization		1,828		2,027
Other		268		98

Total	$	2,401	$	2,397

Deferred financing costs capitalized in 2006, are being amortized over ten years, the term of the mortgage note. Amortization on deferred financing costs was approximately $17,000, $61,000 and $56,000 in 2007, 2006 and 2005, respectively. Amortization on intellectual property was approximately $479,000, $318,000 and $0 in 2007, 2006 and 2005, respectively.

BTU INTERNATIONAL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

INCOME TAXES

Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. The amounts of deferred tax assets or liabilities are based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. A valuation allowance is provided if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax asset will not be realized.

TRANSLATION OF FOREIGN CURRENCIES

Assets and liabilities of the Company’s foreign operations are translated from their functional currency into United States dollars at year end exchange rates. Revenue and expense items are translated at weighted average rates of exchange prevailing during the year. Gains and losses arising from translation are accumulated as a separate component of stockholders’ equity, as the functional currency of the subsidiaries is their local currency, and the reporting currency of the Company is the U.S. dollar. Exchange gains and losses arising from transactions denominated in foreign currencies are included in income as incurred.

PATENTS

The Company has patents in the United States and certain foreign countries for some of its products and processes. No value has been assigned to these patents in the accompanying consolidated financial statements.

REVENUE RECOGNITION

The Company recognizes revenue in accordance with the Securities and Exchange Commission (SEC) Staff Accounting Bulletin (SAB) No. 101, “Revenue Recognition in Financial Statements” as updated by SEC SAB No. 104, “Revenue Recognition.” Under these guidelines, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services rendered, the price is fixed or determinable and payment is reasonably assured. Under these requirements, when the terms of sale include customer acceptance provisions, and compliance with those provisions has not been demonstrated, revenues are recognized upon acceptance. Furthermore, revenues for products that require installation for which the installation is essential to functionality or is not deemed inconsequential or perfunctory are recognized upon completion of installation. Revenues for products sold where installation is not essential to functionality and is deemed inconsequential or perfunctory are recognized upon shipment with estimated installation and warranty costs accrued.

Applying the requirements of SAB No. 101 to future sales arrangements used in the Company’s equipment sales may result in the deferral of the revenue for some equipment sales.

The Company also has certain sales transactions for products, which are not completed within the normal operating cycle of the business. It is the Company’s policy to account for these transactions using the percentage of completion method for revenue recognition purposes when all of the following criteria exist. (1) The Company has received the Customer’s purchase order or entered into a legally binding contract. (2) The Customer is credit worthy and collection is probable or Customer prepayments are required at product completion milestones or specific dates. (3) The sales value of the product to be delivered is significant in amount when compared to the Company’s other products. (4) Product costs can be reasonably estimated; there is no major technological uncertainty and the total engineering, material procurement, product assembly and test cycle time extend over a period of six months or longer.

BTU INTERNATIONAL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Under the percentage of completion method, revenues and gross margins to date are recognized based upon the ratio of costs incurred to date compared to the latest estimate of total costs to complete the product as a percentage of the total contract revenue for the product. Revisions in costs and gross margin percentage estimates are reflected in the period in which the facts causing the revision become known. Provisions for total estimated losses on uncompleted contracts, if any, are made in the period in which such losses are determined. For the year ended 2007, 2006 and 2005, $1,637,179, $1,211,000 and $3,435,000, respectively, was recognized as revenue using the percentage of completion method.

The Company accounts for shipping and handling costs billed to customers in accordance with the Emerging Issues Task Force (EITF) Issue 00-10 “Accounting for Shipping and Handling Fees and Cost.” Amounts billed to customers for shipping and handling costs are recorded as revenues with the associated costs reported as cost of goods sold.

STOCK-BASED COMPENSATION

Effective January 1, 2006, the Company adopted SFAS No. 123(R), “Share-based Payment,” using the modified prospective transition method. Accordingly, the Company has recorded stock-based employee compensation cost using the fair value method starting in 2006. For 2006, adopting this standard resulted in a reduction of income before income taxes of $365,000 and a reduction in net income of $343,000 and a decrease in basic and diluted earnings per share of $0.04 and $0.03, respectively.

Prior to January 1, 2006 employee compensation expense under stock options was reported using the intrinsic value method; therefore, no stock-based compensation cost is reflected in net income for the years ending December 31, 2005, as all options granted had an exercise price equal to or greater than the market price of the underlying common stock at date of grant.

RESEARCH, DEVELOPMENT AND ENGINEERING

Research, development and engineering costs are charged to expense as incurred.

EARNINGS PER SHARE INFORMATION

Basic EPS is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted EPS is computed using the weighted average number of common and dilutive potential common shares outstanding during the period, using the treasury stock method. Due to their antidilutive effect, approximately 202,633, 79,589 and 0 options to purchase common stock were excluded from the calculation of diluted earnings per share for the years ended December 31, 2007, 2006 and 2005, respectively. However, these options could become dilutive in future periods.

Warranties

The Company provides standard warranty coverage for parts and labor for 12 months and special extended material only coverage on certain other products. The Company sets aside a reserve for anticipated warranty claims based on historical warranty claims as a percentage of revenue by product line. The reserve for warranty covers the estimated costs of material, labor and travel. Actual warranty claims incurred are charged against expense. Factors that affect the Company’s product warranty liability include the number of installed units, the anticipated cost of warranty repairs and historical and anticipated rates of warranty claims.

The following table reflects changes in the Company’s accrued warranty account during the fiscal years ended December 31, 2007 and 2006:

CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

SFAS No. 105, “Disclosure of Information about Financial Instruments with Off-Balance-Sheet Risk and Financial Instruments with Concentrations of Credit Risk,” requires disclosure of any significant off-balance-sheet and credit risk concentrations. The Company has one foreign exchange contract. The fair market value of forward foreign exchange contract is determined based on the fair value of similar contracts with similar terms and remaining maturities. The Company maintains the majority of its cash and cash equivalent balances with one financial institution who invests the funds in U.S. Treasury Bills of terms not to exceed 90 days.

The principal financial instrument that potentially subjects the Company to concentrations of credit risk is accounts receivable. The Company’s revenues are primarily derived from customers in the electronics and alternative energy manufacturing industries who are not required to provide collateral for amounts owed to the Company. The Company’s customers are dispersed over a wide-geographic area and are subject to periodic review under the Company’s credit policies. The Company does not believe that it is subject to any unusual credit risks, other than the normal level of risk attendant to operating its business.

Concentration of credit risk with respect to accounts receivable is limited to certain customers to whom the Company makes substantial sales. To reduce its credit risk, the Company routinely assesses the financial strength of its customers. The Company maintains an allowance for potential credit losses, but historically has not experienced any losses in excess of the loss allowance related to individual customers or groups of customers in any particular industry or geographic area.

As of December 31, 2007, there was one customer that individually accounted for 18% of accounts receivable. As of December 31, 2006, there was one customer that individually accounted for 15% and one customer that accounted for 10% of accounts receivable.

The ability of the Company to fully realize deferred tax assets in future years is contingent upon its success in generating sufficient levels of taxable income to use the deductions underlying the assets. After an assessment of all available evidence, including historical and projected operating trends, the company recorded a valuation allowance to offset the majority of the Company’s deferred tax assets due to the uncertainty surrounding their realization. Valuation allowances related to Alternative Minimum Tax (AMT) were reversed as these credits have an indefinite life.

EMPLOYEE BENEFITS

The Company has management incentive and profit sharing plans for its executives and all of its employees. These plans provide for bonuses upon the attainment of certain financial targets. Under these plans, $261,000, $668,000 and $825,000 was expensed in 2007, 2006 and 2005, respectively.

The Company has a deferred 401(k) contribution plan that is available to cover all domestic employees of the Company. Subject to non-discriminatory restrictions on highly compensated employees, participants can voluntarily contribute a percentage of their compensation up to the plan limits, and the Company, at its discretion, may match this contribution up to a stipulated percentage. The Company’s expense under the plan was $184,000, $194,000 and $153,000 for the years ended December 31, 2007, 2006 and 2005, respectively.

STOCK OPTION AND PURCHASE PLANS

On January 1, 2006, the Company adopted the provisions of Financial Accounting Standards Board Statement 123R, Share-Based Payment (“SFAS 123R”). This statement establishes standards for accounting for transactions in which an entity exchanges its equity instruments for goods or services. The statement focuses primarily on accounting for transactions in which an entity obtains employee services in share-based payment transactions, such as the options issued under the Company’s Stock Option Plans. The statement provides for, and the Company has elected to adopt the standard, using the modified prospective application under which compensation cost is recognized on or after the required effective date for the fair value of all future share-based award grants and for the portion of outstanding awards at the date of adoption of this statement for which the requisite service has not been rendered, based on the grant-date fair value of those awards calculated under Statement 123 for pro forma disclosures. The Company’s stock option compensation expense was $744,000 and $365,000 for the year ended December 31, 2007 and 2006, respectively.

The application of SFAS 123R had the following effect on the reported amounts for the years ended December 31, 2007 and December 31, 1006 relative to amounts that would have been reported using the intrinsic value method under previous accounting treatment:


	December 31, 2007						December 31, 2006
123R Effect on Reported Income:	Previous		123R Adj		As Reported		Previous		123R Adj		As Reported
Operating Income		3,403		684		2,719		9,881		350		9,531
Earnings Before Income Taxes		3,338		684		2,654		9,761		350		9,411
Net Income		2,564		616		1,948		9,565		343		9,222

Basic Earnings Per Share	$	0.28	$	0.07	$	0.21	$	1.05	$	0.04	$	1.01
Diluted Earnings Per Share	$	0.27	$	0.07	$	0.20	$	1.01	$	0.03	$	0.98

The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model. This model incorporates certain assumptions for inputs including a risk-free market interest rate, expected dividend yield of the underlying common stock, expected option life and expected volatility in the market value of the underlying common stock. The Company is also required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. Historical data was used to estimate pre-vesting forfeitures and record stock-based compensation expense only for those awards that are expected to vest. We used the following assumptions for options issued during the years ended December 31, 2007 and December 31, 2006 respectively:


	Twelve Months Ended
Calculation of Fair Values—Assumptions Used:	Dec. 31, 2007		Dec 31, 2006
Expected Volatility	65	%	60	%
Expected Life	5		5
Risk-Free Interest Rate	4.79	%	4.96	%
Expected Dividend Yield	None		None

Expected volatilities are based on the weighted average historical volatility of the Company’s common stock for the expected life of the option. The Company had significant historical data to help evaluate the expected lives of options in developing its assumption. The risk-free interest rate is based upon quoted market yields for United States Treasury debt securities. The expected dividend yield is based upon the Company’s history of having never issued a dividend and management’s current expectation of future action surrounding dividends.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Prior to January 1, 2006, the Company accounted for its share-based compensation using the intrinsic value method prescribed in Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. No share-based employee compensation cost was reflected in net income, as all options granted under those plans had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table illustrates the effects on net income and earnings per share for the year ended December 31, 2005, as if the Company had applied the fair value recognition provisions of SFAS 123 to share-based employee awards:


	Year Ended December 31, 2005
	(in thousands, except per share data)
Net income:
As reported	$	4,619
Pro forma	$	4,164
Income per basic share
As reported	$	0.62
Pro forma	$	0.56
Income per diluted share
As reported	$	0.60
Pro forma	$	0.54

Pro forma compensation costs were estimated using the Black-Scholes option pricing model using the following weighted average assumptions for grants in 2005; a dividend yield rate of 0 for the year; expected life of 7.0 years; expected volatility of 60.15%; and risk free interest rate of 4.15%. The weighted average fair value of options granted during 2005 was $3.13.

The Company has two stock option plans for employees, the 1993 Equity Incentive Plan (1993 Plan), which expired in 2003 with 254,791 unissued options, and the 2003 Equity Incentive Plan (2003 Plan). These plans allow for the award of stock and stock options to employees, directors and consultants. Under the terms of the plans, other stock awards can also be granted at the discretion of the Company’s Board of Directors. The Company also has two stock option plans for non-employee directors, the 1989 Stock Plan for Directors (1989 Plan) and the 1998 Stock Option Plan for Non-Employee Directors (1998 Plan). Under each plan, the exercise price of the options is not less than the fair market value at the date of the grant. Options expire from a minimum of two years to a maximum of ten years from the date of the grant.

In May 2003, the shareholders approved the 2003 Equity Incentive Plan, which allows up to 700,000 shares to be awarded (plus the addition of up to 300,000 options that could be forfeited under the expired 1993 Plan). Also in May 2003, the shareholders approved an amendment to add 70,000 shares to the 1998 Stock Option Plan for Non-Employee Directors.

Shares available for future stock option grants, pursuant to these plans, were 462,989 at December 31, 2007, 766,801 at December 31, 2006, and 961,839 at December 31, 2005.

(10) DISCLOSURES ABOUT THE FAIR VALUE OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value.

a. Cash and Cash Equivalents—The carrying amount of these assets on the Company’s Consolidated Balance Sheets approximates their fair value because of the short maturities of these instruments.

b. Receivables, Payables and Accruals—The recorded amounts of financial instruments, including accounts receivable, accounts payable, and accrued liabilities, approximate their fair value because of the short maturity of these instruments.

c. Long-term Debt and Capital Lease Obligations—The fair value of long-term indebtedness as of December 31, 2007 and 2006 was approximately $9,267,0000 and $9,422,000, respectively, based on a discounted cash flow analysis, using the prevailing cost of capital for the Company as of each date. The interest rates used in the calculation were 6.84% and 7.60% for 2007 and 2006, respectively.

d. Foreign Currency Derivative Transactions—During the year ended December 31, 2007, the company began to manage its foreign exchange risk through the use of derivative financial instruments. These financial instruments serve to protect cash flow against the impact of the translation into Chinese RMB of foreign exchange denominated transactions. As of December 31, 2007, the company had a 90-day forward currency contract denominated in U.S. dollars with a notional value of $12.0 million. At December 31, 2007, the fair market value of the outstanding forward exchange contract was approximately $31,000, which was recorded as a foreign exchange gain on the Company’s operating statement.

(11) SEGMENT REPORTING

Segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and in assessing performance. The Company operates as a single business segment called thermal processing capital equipment.

The thermal processing capital equipment segment consists of the designing, manufacturing, selling and servicing of thermal processing equipment and related process controls for use in the electronics, power generation, automotive and other industries. This business segment includes the supply of solder reflow systems used for surface mount applications in printed circuit board assembly. Thermal processing equipment is used in: low temperature curing/encapsulation; hybrid integrated circuit manufacturing; integrated circuit packaging and sealing; and processing multi-chip modules. In addition, the thermal process equipment is used for solar cell processing, sintering nuclear fuel for commercial power generation, as well as brazing and the sintering of ceramics and powdered metals, and the deposition of precise thin film coatings. The business segment’s customers are multinational original equipment manufacturers and contract manufacturing companies.

(12) EXECUTIVE RETIREMENT

Executive Retirement

After returning from retirement to his former duties as the Company’s President and Chief Executive Officer, Mr. Paul J. van der Wansem, in 2005, entered into an agreement with the Company which settled the method and timing of payment for the outstanding compensation of $561,000 due Mr. van der Wansem by the Company under the consulting service provisions of his executive retirement agreement of 2002. The execution of this settlement cancels all the Company’s obligations under the consulting portion of the executive retirement

agreement. In the 2005 contract, the agreed method of payment and timing was set at half of the value to be paid immediately in the form of the Company’s common stock at market value with the remaining half to be paid no later than June 2007. The second half of the amount due under the 2005 agreement was paid in 2007.

(13) ACQUISITIONS

On March 17, 2006, the Company acquired the product lines, trademarks and other related assets of Radiant Technology Corporation (RTC). The purchase price for this acquisition was as follows: 1) $500,000 in cash and 100,000 shares of the Company’s common stock, of which 30,000 shares were contingent upon RTC’s successful achievement of certain non-financial performance criteria; and 2) Royalty payments on any products using the RTC technology manufactured by the Company for a period of 4 years. In addition, the parties entered into a supply agreement under which RTC will continue to manufacture its products for distribution by the Company after the closing.

In the second quarter of 2007, it was determined that, of the additional 30,000 shares of stock that were contingent upon RTC’s successful achievement of certain non-financial performance criteria, 21,000 shares had been earned. On May 3, 2007, 18,000 shares were issued and the additional 3,000 shares were issued on July 16, 2007.

On May 31, 2006, the Company acquired the assets and intellectual property of AtmoPlas, a division of Dana Corporation. The purchase price is as follows: 1) $474,564 in cash; 2) Royalty payments on any products using AtmoPlas technology manufactured by the Company and sold during the third through seventh years after the acquisition with minimum royalties in years three and four of not less than $300,000 per year; and 3) Royalty payments on licensing revenues received from third parties for a period of seven years after the closing date calculated on a percentage basis.

(14) ISSUANCE OF COMMON STOCK

On December 12, 2005, the Company sold 1,250,000 shares of its common stock in a secondary offering raising approximately $15 million in cash, net of approximately $1,271,000 in related issuance costs. The offering allowed the underwriter an option to purchase an additional 187,500 shares of common stock within a 30-day period. On January 11, 2006, the underwriter exercised its option to purchase 87,500 additional shares of common stock. This sale netted the Company approximately $1.1 million in cash. These funds have and will continue to be used to support the Company’s future growth objectives.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of BTU International, Inc.:

We have audited the accompanying consolidated balance sheets of BTU International, Inc. (a Delaware Corporation) and subsidiaries (the Company) as of December 31, 2007 and 2006, and the related consolidated statements of operations, stockholders’ equity, comprehensive income, and cash flows for each of the years in the three-year period ended December 31, 2007. We also have audited the financial statement schedule listed in the accompanying index appearing under Item 15(a)(2). We also have audited the Company’s internal control over financial reporting as of December 31, 2007 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the company’s internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2007 and 2006, and the consolidated results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2007, in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related

consolidated financial statements. Also, in our opinion, the Company maintained effective internal control over financial reporting as of December 31, 2007, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

ITEM 9A.

CONTROLS AND PROCEDURES

1. Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Accounting Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

The Company’s management carried out an evaluation, under the supervision and with the participation of the Chief Executive Officer and the Chief Accounting Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934) as of December 31, 2007, pursuant to the evaluation of these controls and procedures required by Rule 13a-15 of the Securities Exchange Act of 1934.

Based upon that evaluation, Management concluded as of the end of the period covered by this Annual Report on Form 10-K that our disclosure controls and procedures were effective.

2. Internal Control over Financial Reporting

The Management of the Company is responsible for establishing and maintaining adequate internal control over its financial reporting. The Company’s internal control over financial reporting is a process designed under the supervision of the Company’s Chief Executive Officer and Chief Accounting Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis.

The Company’s Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2007 based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in “Internal Control Integrated Framework.”

Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2007, had identified no material weaknesses in the Company’s internal control over financial reporting. As a result, Management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2007. Management believes that the consolidated financial statements included in

this Annual Report on Form 10-K fairly present, in all material respects, the Company’s financial position, results of operations and cash flows for the periods presented.

Vitale, Caturano & Company, Ltd. (VCC), our independent registered public accounting firm has audited the effectiveness of our internal control over financial reporting as of December 31, 2007 and has issued their report which is included herein.
