COHU

Cohu Inc

A maker of machines and software that test and inspect semiconductor chips before they ship, serving computer, automotive, and consumer-electronics companies. It began in 1947 as Kalbfell Laboratories, founded by Dr. David Kalbfell, and took the Cohu name in 1972 after a name used for its electronics division — a nod to Lamott T. Cohu, whose investment group bought the firm in the 1950s. The company once made television cameras and metal detectors before focusing solely on chip testing.
