Abstract
A probe positioning apparatus for use in a probe testing system is disclosed. The probe positioning apparatus includes a probe tip, a probe actuator connected to the probe tip, a probe plate coupled to the probe actuator and a magnetic probe plate clamp that magnetically couples the probe plate. The magnetic coupling forms a slip plane that provides collision compliance for the probe positioning apparatus. One embodiment of the magnetic probe clamp uses a set of shoulder screws to provide quick attachment and release of the probe plate from the probe clamp. A second embodiment uses a magnetic shunt to disable the magnetic connection of the clamp from the probe plate.
