What it does
Cohu makes the equipment that moves chips through final test: pick-and-place and turret handlers, test contactors, thermal subsystems, and analytics software that monitors how its own tools perform. Its customers are semiconductor manufacturers and outsourced test subcontractors who need a device handled and held in place while a tester checks it. It is based in San Diego and sells directly and through independent sales representatives across several manufacturing regions.
Where it sits in the stack
In our index, Cohu sits in Layer 3, Assembly & Test, within the Testing & Metrology sleeve — the group of ATE testers, inspection and metrology vendors that keeps yield curves honest as nodes shrink. Cohu supplies the handling side of that sleeve, the machinery that presents each device to a tester rather than the tester itself, so it is a customer of the same volume that drives ATE demand.
Who it is priced against
The diary groups it with the sleeve's testing and metrology names — Teradyne, Onto Innovation, KLA, Camtek, PDF Solutions, Nova, Aehr Test Systems and Advantest, the last two named as the ATE market leader and its closest rival.
Why Closelooknet tracks it
Cohu is a Rubin Build-Out 100 constituent and carries a Closelooknet score, strongest on momentum and weakest on quality. It has appeared in a piece on the testing bottleneck as the handler name alongside Advantest and Teradyne, and in a Morning 10 note flagging it among names testing chart support at the same time.
What the diary watches
Whether handler orders keep pace with ATE demand as device complexity rises, since Cohu's volume depends on the same test intensity that drives the rest of its sleeve.
