Accounting Policies [Abstract]  
Basis of Accounting, Policy [Policy Text Block]
Basis of Presentation
 
Our fiscal years are based on a
52
- or
53
-week period ending on the last Saturday in
December.
The condensed consolidated balance sheet at
December 29, 2018,
has been derived from our audited financial statements at that date. The interim condensed consolidated financial statements as of
September 28, 2019, (
also referred to as “the
third
quarter of fiscal
2019”
and “the
first
nine
months of fiscal
2019”
) and
September 29, 2018, (
also referred to as “the
third
quarter of fiscal
2018”
and “the
first
nine
months of fiscal
2018”
) are unaudited. However, in management’s opinion, these financial statements reflect all adjustments (consisting only of normal, recurring items) necessary to provide a fair presentation of our financial position, results of operations and cash flows for the periods presented. Both the
three
- and
nine
-month periods ended
September 28, 2019
and
September 29, 2018,
were comprised of
13
and
39
weeks, respectively.
 
Our interim results are
not
necessarily indicative of the results that should be expected for the full year. For a better understanding of Cohu, Inc. and our financial statements, we recommend reading these interim condensed consolidated financial statements in conjunction with our audited financial statements for the year ended
December 29, 2018,
which are included in our
2018
Annual Report on Form
10
-K, filed with the U. S. Securities and Exchange Commission (“SEC”). In the following notes to our interim condensed consolidated financial statements, Cohu, Inc. is referred to as “Cohu”, “we”, “our” and “us”.
 
The condensed consolidated financial statements include the accounts of Cohu and a variable interest entity (“VIE”) that was acquired as part of our acquisition of Xcerra Corporation (“Xcerra”) and in which we have determined we are the primary beneficiary. The non-controlling interest in ALBS Solutions Sdn Bhd (“ALBS”) represents the
80%
equity interest that is
not
held by Cohu. ALBS is a privately held corporation which provides high-tech semiconductor automation systems to different industrial users. All significant consolidated transactions and balances have been eliminated in consolidation.
Consolidation, Variable Interest Entity, Policy [Policy Text Block]
Principles of Consolidation for Variable Interest Entities
 
We follow ASC Topic
810
-

-

guidance with respect to accounting for VIEs. These entities do
not
have sufficient equity at risk to finance their activities without additional subordinated financial support from other parties or whose equity investors lack any of the characteristics of a controlling financial interest. A variable interest is an investment or other interest that will absorb portions of a VIE’s expected losses or receive portions of its expected residual returns and are contractual, ownership, or pecuniary in nature and that change with changes in the fair value of the entity’s net assets. A reporting entity is the primary beneficiary of a VIE and must consolidate it when that party has a variable interest, or combination of variable interests, that provides it with a controlling financial interest. A party is deemed to have a controlling financial interest if it meets both of the power and losses/benefits criteria. The power criterion is the ability to direct the activities of the VIE that most significantly impact its economic performance. The losses/benefits criterion is the obligation to absorb losses from, or right to receive benefits from, the VIE that could potentially be significant to the VIE. The VIE model requires an ongoing reconsideration of whether a reporting entity is the primary beneficiary of a VIE due to changes in facts and circumstances.
 
As of
September 28, 2019
and
December 29, 2018,
we consolidated
one
VIE. Cohu is the primary beneficiary of ALBS which qualifies as a VIE that meets the definition of a business. As such, the assets, liabilities, and noncontrolling interest of ALBS were measured at fair value upon acquisition in accordance with ASC
805,
Business Combinations
(“ASC
805”
). The assets and liabilities and revenues and expenses of this VIE are included in our condensed consolidated financial statements. As of
September 28, 2019
and
December 29, 2018,
the assets and liabilities of ALBS are immaterial to Cohu and, therefore,
not
shown separately on our condensed consolidated balance sheets. The
third
-party equity interest of ALBS is referred to as noncontrolling interest. The portion of net income (loss) attributable to the noncontrolling interest of ALBS is presented as net income (loss) allocated to noncontrolling interests in the condensed consolidated statements of operations and comprehensive loss, and the portion of stockholders' equity of ALBS is presented as noncontrolling interest in the condensed consolidated statements of stockholders' equity.
Reclassification, Policy [Policy Text Block]
Reclassifications
In conjunction with the acquisition of Xcerra we assessed the need to realign our financial statement presentation and certain income statement classifications were adjusted with prior periods reclassified to conform with current period presentation. The changes made were as follows:
 
 
Amortization of intangibles previously were presented in cost of sales and SG&A. These amounts are now presented as a separate line item “Amortization of purchased intangible assets” within operating expenses.
 
 
Gains and losses associated with foreign currency translation and remeasurement were included within SG&A. These amounts are now presented as “Foreign transaction gain (loss)”.
 
A summary of the reclassifications described above and the impact on our condensed consolidated statements of operations is as follows:

Concentration Risk, Credit Risk, Policy [Policy Text Block]
Concentration of Credit Risk
 
Financial instruments that potentially subject us to significant credit risk consist principally of cash equivalents, short-term investments and trade accounts receivable. We invest in a variety of financial instruments and, by policy, limit the amount of credit exposure with any
one
issuer.
 
Trade accounts receivable are presented net of allowance for doubtful accounts of
$0.2
 million at
September 28, 2019,
and
$0.3
million at 
December 29, 2018.
Our customers include semiconductor manufacturers and semiconductor test subcontractors throughout many areas of the world. While we believe that our allowance for doubtful accounts is adequate and represents our best estimate at
September 28, 2019,
we will continue to monitor customer liquidity and other economic conditions, which
may
result in changes to our estimates regarding collectability.
Inventory, Policy [Policy Text Block]
Inventories
 
Inventories are stated at the lower of cost, determined on a
first
-in,
first
-out basis, or net realizable value. Cost includes labor, material and overhead costs. Determining net realizable value of inventories involves numerous estimates and judgments including projecting average selling prices and sales volumes for future periods and costs to complete and dispose of inventory. As a result of these analyses, we record a charge to cost of sales in advance of the period when the inventory is sold when estimated net realizable values are below our costs.
 
Inventories by category were as follows (

Property, Plant and Equipment, Policy [Policy Text Block]
Property, Plant and Equipment
 
Depreciation and amortization of property, plant and equipment, both owned and under financing lease, is calculated principally on the straight-line method based on estimated useful lives of
thirty
to
forty
years for buildings,
five
to
fifteen
years for building improvements and
three
to
ten
years for machinery, equipment and software. Land is
not
depreciated.

Segment Reporting, Policy [Policy Text Block]
Segment Information
 
We applied the provisions of ASC Topic
280,
Segment Reporting
, (“ASC
280”
), which sets forth a management approach to segment reporting and establishes requirements to report selected segment information quarterly and to report annually entity-wide disclosures about products, major customers and the geographies in which the entity holds material assets and reports revenue. An operating segment is defined as a component that engages in business activities whose operating results are reviewed by the chief operating decision maker and for which discrete financial information is available. Subsequent to the acquisition of Xcerra on
October 1, 2018,
we have determined that our
four
identified operating segments are: Test Handler Group (THG), Semiconductor Tester Group (STG), Interface Solutions Group (ISG) and PCB Test Group (PTG). Our THG, STG and ISG operating segments qualify for aggregation under ASC
280
due to similarities in their customers, their economic characteristics, and the nature of products and services provided. As a result, we report in
two
segments, Semiconductor Test and Inspection Equipment (“Semiconductor Test & Inspection”) and PCB Test Equipment (“PCB Test”).
Goodwill and Intangible Assets, Policy [Policy Text Block]
Goodwill, Other Intangible Assets and
Long-lived Assets
 
We evaluate goodwill for impairment annually and when an event occurs or circumstances change that indicate that the carrying value
may
not
be recoverable. We test goodwill for impairment by comparing the book value of net assets to the fair value of the reporting units. If the fair value is determined to be less than the book value, an impairment charge is recognized as the amount by which the carrying amount of goodwill exceeds the reporting unit's fair value,
not
to exceed the carrying amount of goodwill. We estimated the fair values of our reporting units primarily using the income approach valuation methodology that includes the discounted cash flow method, taking into consideration the market approach and certain market multiples as a validation of the values derived using the discounted cash flow methodology. Forecasts of future cash flows are based on our best estimate of future net sales and operating expenses, based primarily on customer forecasts, industry trade organization data and general economic conditions.
 
We conduct our annual impairment test as of
October 
1st
 of each year, and have determined there was
no
impairment as of
October 
1,
2018
as we determined that the estimated fair values of our reporting units exceeded their carrying values on that date. Other events and changes in circumstances
may
also require goodwill to be tested for impairment between annual measurement dates. As of
September 28, 2019,
we do
not
believe that circumstances have occurred that indicate impairment of our goodwill is more-likely-than-
not.
In the event we determine that an interim goodwill impairment review is required in a future period, the review
may
result in an impairment charge, which would have a negative impact on our results of operations.
 
We evaluate our indefinite-lived intangible assets associated with in-process research and development by comparing the fair value of each project with its carrying value. This evaluation is completed annually and whenever indicators of impairment are present.
 
Long-lived assets, other than goodwill, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets might
not
be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the observable market value of an asset, a significant change in the extent or manner in which an asset is used, or any other significant adverse change that would indicate that the carrying amount of an asset or group of assets
may
not
be recoverable. For long-lived assets, impairment losses are only recorded if the asset’s carrying amount is
not
recoverable through its undiscounted, probability-weighted future cash flows. We measure the impairment loss based on the difference between the carrying amount and estimated fair value.
Standard Product Warranty, Policy [Policy Text Block]
Product Warranty
 
Product warranty costs are accrued in the period sales are recognized. Our products are generally sold with standard warranty periods, which differ by product, ranging from
12
- to
36
-months. Parts and labor are typically covered under the terms of the warranty agreement. Our warranty expense accruals are based on historical and estimated costs by product and configuration. From time-to-time we offer customers extended warranties beyond the standard warranty period. In those situations the revenue relating to the extended warranty is deferred at its estimated relative standalone selling price and recognized on a straight-line basis over the contract period. Costs associated with our extended warranty contracts are expensed as incurred.
Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block]
Restructuring Costs
 
We record restructuring activities including costs for
one
-time termination benefits in accordance with ASC Topic
420
(“ASC
420”
),
Exit or Disposal Cost Obligations.
The timing of recognition for severance costs accounted for under ASC
420
depends on whether employees are required to render service until they are terminated in order to receive the termination benefits. If employees are required to render service until they are terminated in order to receive the termination benefits, a liability is recognized ratably over the future service period. Otherwise, a liability is recognized when management has committed to a restructuring plan and has communicated those actions to employees. Employee termination benefits covered by existing benefit arrangements are recorded in accordance with ASC Topic
712,
Nonretirement Postemployment Benefits.
These costs are recognized when management has committed to a restructuring plan and the severance costs are probable and estimable.
Debt, Policy [Policy Text Block]
Debt Issuance Costs
 
We capitalized costs related to the issuance of debt. Debt issuance costs directly related to our Term B Loan are presented within noncurrent liabilities as a reduction of long-term debt in our condensed consolidated balance sheets. The amortization of such costs is recognized as interest expense using the effective interest method over the term of the respective debt issue. Amortization related to deferred debt issuance costs and original discount costs was
$0.3
 million and
$0.8
 million for the
three
and
nine
months ended
September 28, 2019.
We obtained the Term B Loan on
October 1, 2018,
as a result there were
no
debt issuance costs amortized during the
three
and
nine
months ended
September 29, 2018.
Foreign Currency Transactions and Translations Policy [Policy Text Block]
Foreign Remeasurement and Currency Translation
 
Assets and liabilities of our wholly owned foreign subsidiaries that use the U.S. Dollar as their functional currency are re-measured using exchange rates in effect at the end of the period, except for nonmonetary assets, such as inventories and property, plant and equipment, which are re-measured using historical exchange rates. Revenues and costs are re-measured using average exchange rates for the period, except for costs related to those balance sheet items that are re-measured using historical exchange rates. Gains and losses on foreign currency transactions are recognized as incurred. During the
three
and
nine
months ended
September 28, 2019,
we recognized foreign exchange gains of
$1.6
 million and
$1.3
 million, respectively, in our condensed consolidated statements of operations. During the
three
and
nine
months ended
September 29, 2018,
we recognized a foreign exchange loss of
$0.2
 million and a gain of
$1.2
 million, respectively, in our condensed consolidated statements of operations. Certain of our foreign subsidiaries have designated the local currency as their functional currency and, as a result, their assets and liabilities are translated at the rate of exchange at the balance sheet date, while revenue and expenses are translated using the average exchange rate for the period. Cumulative foreign currency translation adjustments resulting from the translation of the financial statements are included as a separate component of stockholders’ equity.
Share-based Payment Arrangement [Policy Text Block]
Share-Based Compensation
 
We measure and recognize all share-based compensation under the fair value method. Our estimate of share-based compensation expense requires a number of complex and subjective assumptions including our stock price volatility, employee exercise patterns (expected life of the options) and related tax effects. The assumptions used in calculating the fair value of share-based awards represent our best estimates, but these estimates involve inherent uncertainties and the application of management judgment. Although we believe the assumptions and estimates we have made are reasonable and appropriate, changes in assumptions could materially impact our reported financial results.
 
Reported share-based compensation is classified, in our condensed consolidated financial statements, as follows

Earnings Per Share, Policy [Policy Text Block]
Income (Loss) Per Share
 
Basic income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the reporting period. Diluted income (loss) per share includes the dilutive effect of common shares potentially issuable upon the exercise of stock options, vesting of outstanding restricted stock and performance stock units and issuance of stock under our employee stock purchase plan using the treasury stock method. In loss periods, potentially dilutive securities are excluded from the per share computations due to their anti-dilutive effect. For purposes of computing diluted income (loss) per share, stock options with exercise prices that exceed the average fair market value of our common stock for the period are excluded. For the
three
and
nine
months ended
September 28, 2019,
stock options and awards to issue approximately
459,000
and
487,000
shares of common stock were excluded from the computation, respectively. For the
three
months ended
September 29, 2018,
no
stock options or awards to issue shares of common stock were excluded from the computation. For the
nine
months ended
September 29, 2018,
stock options and awards to issue approximately
12,000
shares of common stock were excluded from the computation.

Cohu has utilized the “control number” concept in the computation of diluted earnings per share to determine whether potential common stock instruments are dilutive. The control number used is income from continuing operations. The control number concept requires that the same number of potentially dilutive securities applied in computing diluted earnings per share from continuing operations be applied to all other categories of income or loss, regardless of their anti-dilutive effect on such categories.
Lessee, Leases [Policy Text Block]
Leases
 
We adopted
ASU
2016
-
02,
Leases (Topic
842
)
, as of
December 30, 2018.
We determine if a contract contains a lease at inception. Operating leases are included in operating lease right of use (“ROU”) assets, current other accrued liabilities, and long-term lease liabilities on our condensed consolidated balance sheets. Finance leases are included in property, plant and equipment, other current accrued liabilities, and long-term lease liabilities on our condensed consolidated balance sheets.
 
Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the adoption date or the commencement date for leases entered into after the adoption date. As most of our leases do
not
provide an implicit rate, we use our incremental borrowing rates for the remaining lease terms based on the information available at the adoption date or commencement date in determining the present value of future payments.
 
The operating lease ROU asset also includes any lease payments made, lease incentives, favorable and unfavorable lease terms recognized in business acquisitions and excludes initial direct costs incurred and variable lease payments. Variable lease payments include estimated payments that are subject to reconciliations throughout the lease term, increases or decreases in the contractual rent payments as a result of changes in indices or interest rates and tax payments that are based on prevailing rates. Our lease terms
may
include renewal options to extend the lease when it is reasonably certain that we will exercise those options. In addition, we include purchase option amounts in our calculations when it is reasonably certain that we will exercise those options. Rent expense for minimum payments under operating leases is recognized on a straight-line basis over the term.
 
Leases with an initial term of
12
months or less are
not
recorded on the balance sheet, but recognized in our condensed consolidated statements of operations on a straight-line basis over the lease term. We account for lease and non-lease components as a single lease component and include both in our calculation of the ROU assets and lease liabilities.
 
We sublease certain leased assets to
third
parties, mainly as a result of unused space in our facilities.
None
of our subleases contain extension options. Variable lease payments in our subleases include tax payments that are based on prevailing rates. We account for lease and non-lease components as a single lease component.
Revenue [Policy Text Block]
Revenue Recognition
 
Our net sales are derived from the sale of products and services and are adjusted for estimated returns and allowances, which historically have been insignificant. We recognize revenue when the obligations under the terms of a contract with our customers are satisfied; generally, this occurs with the transfer of control of our systems, non-system products or services. In circumstances where control is
not
transferred until destination or acceptance, we defer revenue recognition until such events occur.
 
Revenue for established products that have previously satisfied a customer’s acceptance requirements is generally recognized upon shipment. In cases where a prior history of customer acceptance cannot be demonstrated or from sales where customer payment dates are
not
determinable and in the case of new products, revenue and cost of sales are deferred until customer acceptance has been received. Our post-shipment obligations typically include installation and standard warranties. The relative standalone selling price of installation related revenue is recognized in the period the installation is performed. Service revenue is recognized over time as we transfer control to our customer for the related contract or upon completion of the services if they are short-term in nature. Spares, contactor and kit revenue is generally recognized upon shipment.
 
Certain of our equipment sales have multiple performance obligations. These arrangements involve the delivery or performance of multiple performance obligations, and transfer of control of performance obligations
may
occur at different points in time or over different periods of time. For arrangements containing multiple performance obligations, the revenue relating to the undelivered performance obligation is deferred using the relative standalone selling price method utilizing estimated sales prices until satisfaction of the deferred performance obligation.
 
Unsatisfied performance obligations primarily represent contracts for products with future delivery dates. At
September 28, 2019,
we have
$12.2
 million of revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) for contracts with original expected durations of over
one
year. As allowed under ASC
606,
we have opted to
not
disclose unsatisfied performance obligations for contracts with original expected durations of less than
one
year.
 
We generally sell our equipment with a product warranty. The product warranty provides assurance to customers that delivered products are as specified in the contract (an “assurance-type warranty”). Therefore, we account for such product warranties under ASC
460,
Guarantees
(ASC
460
), and
not
as a separate performance obligation.
 
The transaction price reflects our expectations about the consideration we will be entitled to receive from the customer and
may
include fixed or variable amounts. Fixed consideration primarily includes sales to customers that are known as of the end of the reporting period. Variable consideration includes sales in which the amount of consideration that we will receive is unknown as of the end of a reporting period. Such consideration primarily includes sales made to certain customers with cumulative tier volume discounts offered. Variable consideration arrangements are rare; however, when they occur, we estimate variable consideration as the expected value to which we expect to be entitled. Included in the transaction price estimate are amounts in which it is probable that a significant reversal of cumulative revenue recognized will
not
occur when the uncertainty associated with the variable consideration is subsequently resolved. Variable consideration that does
not
meet revenue recognition criteria is deferred. 
 
Our contracts are typically less than
one
year in duration and we have elected to use the practical expedient available in ASC
606
to expense cost to obtain contracts as they are incurred because they would be amortized over less than
one
year.
 
Accounts receivable represents our unconditional right to receive consideration from our customer. Payments terms do
not
exceed
one
year from the invoice date and therefore do
not
include a significant financing component. To date, there have been
no
material impairment losses on accounts receivable. There were
no
material contract assets or contract liabilities recorded on our condensed consolidated balance sheet in any of the periods presented.
 
On shipments where sales are
not
recognized, gross profit is generally recorded as deferred profit in our condensed consolidated balance sheet representing the difference between the receivable recorded and the inventory shipped. At
September 28, 2019,
we had deferred revenue totaling approximately
$16.2
 million, current deferred profit of
$8.0
 million and deferred profit expected to be recognized after
one
year included in noncurrent other accrued liabilities of
$5.8
 million. At
December 29, 2018,
we had deferred revenue totaling approximately
$10.8
 million, current deferred profit of
$6.9
 million and deferred profit expected to be recognized after
one
year included in noncurrent other accrued liabilities of
$2.0
 million.

After the acquisition of Xcerra on
October 1, 2018
we report in
two
segments, Semiconductor Test & Inspection and PCB Test. Cohu’s historical reported net sales would have been reported in our Semiconductor Test & Inspection segment and have been presented accordingly.
Comprehensive Income, Policy [Policy Text Block]
Accumulated Other Comprehensive Loss
 
Our accumulated other comprehensive loss balance totaled approximately
$40.3
 million and
$25.9
 million at
September 28, 2019
and
December 29, 2018,
respectively, and was attributed to all non-owner changes in stockholders’ equity and consists of, on an after-tax basis where applicable, foreign currency adjustments resulting from the translation of certain of our subsidiary accounts where the functional currency is
not
the U.S. Dollar and adjustments related to postretirement benefits. Reclassification adjustments from accumulated other comprehensive loss during the
first
nine
months of fiscal
2019
and
2018
were
not
significant.
Pension and Other Postretirement Plans, Policy [Policy Text Block]
Retiree Medical Benefits
 
We provide post-retirement health benefits to certain retired executives,
one
director (who is a former executive) and their eligible dependents under a noncontributory plan. These benefits are
no
longer offered to any other retired Cohu employees. The net periodic benefit cost incurred during the
first
nine
months of fiscal
2019
and
2018
was
not
significant.
Discontinued Operations, Policy [Policy Text Block]
Discontinued Operations
 
Management has determined that the fixtures services business, that was acquired as part of Xcerra, does
not
align with Cohu’s long-term strategic plan and management is in the process of divesting this portion of the business. As a result, the assets of our fixtures business are considered “held for sale” and the operations of our fixtures business are considered “discontinued operations” as of
December 29, 2018.
See Note
10,
“Discontinued Operations” for additional information. Unless otherwise indicated, all amounts herein relate to continuing operations.
New Accounting Pronouncements, Policy [Policy Text Block]
Recent Accounting Pronouncements
 
Recently Adopted Accounting Pronouncements
 
 
We adopted
ASU
2016
-
02,
Leases (Topic
842
)
, as of
December 30, 2018,
using the optional transition method which allowed us to record existing leases at adoption and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented. We elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allows us to carryforward the historical lease classification.
 
We made an accounting policy election to
not
record ROU assets and lease liabilities for leases with an initial term of
12
months or less. We recognized those lease payments in our condensed consolidated statements of operations on a straight-line basis over the lease term. We also made an accounting policy election to use the practical expedient allowed in the standard to
not
separate lease and non-lease components when calculating the ROU asset and lease liability. Related to adoption of the new standard, we have implemented internal controls and a lease accounting technology system to track the ROU asset and lease liability balances and prepare the related footnote disclosures.
 
Adoption of the new standard resulted in the recording of additional net lease assets and lease liabilities of approximately
$30.7
 million and
$29.9
 million, respectively, as of
December 30, 2018.
We had previously recorded a sale and operating leaseback transaction in accordance with Topic
840
and as a result of the adoption of the new standard, recognized
$10.2
 million of deferred gain as an adjustment to retained earnings. In addition, we had previously recognized assets and liabilities related to a build-to-suit designation under Topic
840
and as a result of the adoption of the new standard, derecognized assets and liabilities of
$0.5
 million and
$0.6
 million, respectively, with the difference recorded as an adjustment to retained earnings. The standard did
not
materially impact our consolidated net earnings and had
no
impact on cash flows.

as amended, affects trade receivables, financial assets and certain other instruments that are
not
measured at fair value through net income. This ASU will replace the currently required incurred loss approach with an expected loss model for instruments measured at amortized cost and is effective for financial statements issued for fiscal years beginning after
December 15, 2019,
including interim periods within those fiscal years. We do
not
expect the adoption of this guidance to have a material impact on our condensed consolidated financial statements.
