High-precision and flexible testing of electroformed spring elements
Sigrist GmbH, headquartered in Pforzheim, Germany manufactures electroformed spring elements for the aerospace, medical and semiconductor industries. These components are high-precision, flexible or spring-like, and consist of an electroplated layer with a functional wall thickness of 0.015 to 0.1 mm. When compressing and relaxing the components, a life expectancy of sometimes more than 100 million cycles is expected without a significant change in the spring rate, e.g. when being used with automatic circuit board assembly machines (pick and place).
