Spring-loaded pushrod

Spring-loaded tooling pins (GFS) are used to spring-mount the printed circuit boards to be tested using the tooling holes, and position them precisely at the contacting level in the probe field. Depending on the design, the spring-loaded tooling pins are mounted either on the probe plate (KTP) or the moving plate (ADP). The collar of the tooling pin must always sit flush on the plate.
