Cohu, Inc. (Cohu), incorporated on January 2, 1957, is a supplier of semiconductor test and inspection handlers, micro-electro mechanical system (MEMS) test modules, test contactors and thermal sub-systems used by global semiconductor manufacturers and test subcontractors. The Company develops, manufactures, sells and services a line of equipment capable of handling a range of integrated circuits and light-emitting diodes (LEDs). It operates through semiconductor equipment segment. It offers products for the pick-and-place, gravity-feed, test-in-strip and turret handling, MEMS, burn-in and system-level test markets. It sells various products, including Delta MATRiX, Delta Pyramid, Delta Eclipse, Delta LinX, Rasco SO1000, Rasco SO2000, Rasco Saturn and Jupiter, Rasco Jaguar, Ismeca NY32, Ismeca NY20 and Delta Fusion HD. Its principal manufacturing operations are located in Malacca, Malaysia (handlers); Poway, California (thermal subsystems); Laguna, the Philippines (kits and contactors); Kolbermoor, Germany (handlers); Osaka, Japan (contactors).

The Company's Delta MATRiX is a pick-and-place handler capable of thermally conditioning devices from -60 degrees Celsius to +175 degrees Celsius. Its Delta Pyramid is a thermal handler for microprocessors, graphics processors and other integrated circuits. The Pyramid incorporates its T-Core thermal control technology that optimizes test yield of power dissipative integrated circuits. Delta Eclipse is its pick-and-place platform tailored for Fabless and Outsourced Semiconductor Assembly and Test (OSAT) customers, as well as integrated device manufacturers (IDMs). Delta LinX is its platform serving assembly automation. The LinX product line offers advanced Joint Electron Device Engineering Council (JEDEC) handing automation that links various assembly test processes.

As of December 31, 2016, the Company's Rasco SO1000 is a gravity-feed platform that provides a solution for testing four devices in parallel. This handler can be configured for tube-to-tube or metal magazine input and output, ambient-hot or tri-temperature testing and is kit-able for a range of integrated circuit packages. As of December 31, 2016, its Rasco SO2000 is a platform that offers a solution for testing small integrated circuit packages four devices in parallel. The base platform can be configured with various input and output modules: tube, metal magazine, bowl, bulk, tape and reel, and an optional laser marking unit. This handler can be configured for ambient-hot or tri-temperature testing. As of December 31, 2016, Rasco Saturn and Jupiter were its gravity handlers delivering an index time capability with eight devices tested in parallel at cold and/or hot temperature. Saturn has a configuration that covers testing of very small to medium size packaged integrated circuits, and Jupiter is a version that enables testing of medium to very large packaged integrated circuits serving the power management device market.

The Company's Rasco Jaguar test-in-strip handler can process an entire strip at once or index the strip for single/multiple device testing. The Jaguar is also a solution for in-process testing of multi-stacked packages. Its Ismeca NY32 is a 32-position turret handler used for testing and inspection of integrated circuits, LEDs and discrete devices. There are various configurations of the NY32 turret handler: handling wafers in film-frame for input and/or output that is common for LEDs and wafer level package (WLP) devices; tray and tube input and/or output used for integrated circuits and discrete devices, and bowl feeding, tape and de-taping, alignment, laser marking, inspection and test modules. Its Ismeca NY20 is a turret handler platform that delivers high throughput combined with fast device change-over time for both high-volume and high-mix testing and inspection of integrated circuits, LEDs and discrete devices. The 20-position turret offers various functional modules and capabilities available on the NY32 platform in a smaller footprint, higher throughput handler. Its MEMS modules can be integrated into its pick-and-place, turret, test-in-strip, or gravity-feed handlers.

The Company's Delta T-Core thermal sub-systems provide temperature control of the integrated circuit during the testing process using the same technology available in the Pyramid handler. T-Core is also used in engineering device characterization applications. Its Delta Fusion HD is a tri-temperature thermal sub-system that utilizes T-Core technology for testing mobile processors. It designs, manufactures, sells and supports various lines of test contactor solutions. It provides consumable and non-consumable items that are used to maintain, sustain or otherwise enable customer's equipment to meet its performance, availability and production requirements. It designs and manufactures a range of device dedication kits that enable handlers to process various semiconductor packages. Its Philippines and China operations design and manufacture its handler kits and provide applications support to customers in the southeast Asia region.
