The test systems are meant to be flexible and run with high parallelism, testing up to 32 MEMS ICs in parallel. They boast a modular design for integration on gravity-feed, test-in-strip, and pick-and-place handlers.
The ATU tests audio devices used in a variety of consumer electronics and automotive applications.
The PTU offers high accuracy testing of integrated pressure sensors used in the automotive market.
Rasco also offers magnetic, optical and temperature sensor device testers.
The MEMS test tools debuted at Semicon West 2011.
Cohu, through its Delta Design and Rasco subsidiaries, is a supplier of test handling, burn-in, thermal subsystems and MEMS test solutions used by the global semiconductor industry. Cohu acquired Rasco in 2008. Learn more at www.cohu.com
