About CRS Prüftechnik
Founded in the early 1990s, CRS Prüftechnik GmbH from Konstanz manufactures and sells highly complex inline test systems for the electronics industry. The portfolio includes inline test stations (IPS-19, IPS-32) for in-circuit testing of printed circuit boards, the Multi Level Tester MLT 4, fully automatic end-of-line test lines for DBCs and power semiconductors, as well as test adapters, solder masks, marking and identification systems. In addition, special-purpose machines and complete solutions with robot handling, fail ejection and camera systems are developed and built. The value chain ranges from in-house design through CNC milling, CNC turning and CNC drilling, profile frame and fixture construction to programming (PLC, robotics, EPLAN) and assembly. Service and maintenance with maintenance contracts round off the offering. Customers come from the electronics, power electronics and automotive industries, including Bosch, Siemens, Sick, Rohde & Schwarz and Danfoss Silicon Power.
