Abstract

A probe card assembly has a probe contactor substrate having a plurality of probe contactor tips thereon and a probe card wiring board with an interposer disposed between the two. Support posts contacting the probe contactor substrate are vertically adjustable until secured by a locking mechanism which is coupled to the probe card wiring board. When the posts are secured in a fixed position, the position is one in which the plane of the plurality of probe contactor substrates is substantially parallel to a predetermined reference plane.
