Exhibit 99.1

Kulicke & Soffa Reports Results for its Second Fiscal Quarter

•     Third Quarter Revenue Guidance: $167 Million (17% Q-Q Increase)

Fort Washington, PA – April 30, 2007—Kulicke & Soffa Industries, Inc. (Nasdaq: KLIC) today announced financial results for its quarter ended March 31, 2007 (second quarter).

Net revenue from continuing operations for the second quarter was $142.7 million compared to $152.3 million for the previous quarter and $160.3 million for the comparable year-ago quarter.

Net loss from continuing operations was $2.2 million or $0.04 per diluted share, versus net income of $4.2 million or $0.06 per diluted share for the previous quarter, and $17.1 million or $0.25 per diluted share for the year-ago quarter. The net loss from continuing operations for the second quarter includes $1.1 million of expenses related to our die bonder integration activities.

Included in net revenue from continuing operations for the second quarter is $71.6 million of gold metal content compared to $71.0 million for the previous quarter and $63.4 million for the year-ago quarter. These amounts are included in both our revenue and cost of sales. The cost of the gold metal content of our wire is passed through to our customers without generating a profit.

Scott Kulicke, chairman and chief executive officer, commented, “While the quarter started very slowly, we saw a significant shift in customer sentiment late in the quarter. This caused an end-of-quarter spike in shipments as well as a much stronger June quarter forecast.”

Second Quarter Review:

Key Product Highlights

• K&S ball bonder products gained market share at several customers producing memory devices. These customers represent both memory manufacturers and subcontractors for the memory market.

• K&S introduced the new 9022 HSL-Plus die bonder for the DRAM market with improved reliability, yield, and flexibility. The new model won its initial orders in the second quarter at a primary memory manufacturer.

• K&S also introduced the high speed Easyline 8202 die bonder. During its initial evaluation at a customer site, the new machine reached throughput speeds approximately 20-30% (depending on application) faster than the previous configuration.

• Several customer locations began using the new CupraPlus capillary for the production of copper wire bonded packages. Other customers are now interested in this product, which enhances copper bonding yield. In parallel, many of these

customers are also starting to qualify K&S’s Maxsoft, the newest copper wire product with improved bonding properties.

• K&S began shipping production quantities of its new Radix gold wire product. Two major subcontractors have already qualified this new wire, which is used for complex, stacked-die packages.

Financial Review

• Equipment gross margins declined to 40% from 43% in the first quarter. The lower gross margin was partially due to a higher percentage of sales of equipment with fewer options and features.

• Cash, cash equivalents, and short-term investments decreased approximately $10 million, from $139.5 million at the end of the first quarter to $129.3 million. The decrease was primarily attributable to a $5.4 million increase in accounts receivable due to a sharp increase in equipment shipments late in the second quarter and a $5.5 million increase in inventory to meet higher anticipated production levels in the third quarter.

Guidance for Third Fiscal Quarter:

Mr. Kulicke provided the following revenue guidance, “We expect business conditions to continue to significantly improve in the June quarter. Based on current gold prices, we believe revenue will be about $167 million, due primarily to strengthening equipment sales.”
