Abstract

An interface between a test head portion of automatic test equipment and handling device such as a prober. The interface employs preloaded kinematic couplings between the test head and handling device and between the probe card and the test head. These couplings allow the probe card to be repeatedly positioned relative to the component in the handling device. They also reduce forces on the probe card to prevent distortion of the probe card. The interface provide seperate mechanical and electrical loops such that mechanical position is not dependant on the electrical structure.
