Qualitau Ltd

A maker of semiconductor reliability testing systems, Qualitau builds equipment that stress-tests microchips to predict how long they will last, used by chipmakers around the world. Founded in 1991 in Migdal HaEmek, Israel, the company's name blends "quality" with "tau," the Greek letter reliability engineers use for the time-to-failure constant. Its systems help semiconductor manufacturers catch weak chips before they reach the market.
