Patent ID: 7167010

Claim:
A probe card for contacting a portion of a semiconductor substrate, the probe card comprising: an upper keeper plate comprising a first substantially planar substrate having at least one upper via extending therethrough, at least a first electrically conductive upper contact pin partially embedded in and extending through an elastomeric material disposed in the at least one upper via; a lower keeper plate comprising a second substantially planar substrate having at least one lower via extending therethrough, at least a first electrically conductive lower contact pin partially embedded in and extending through an elastomeric material disposed in the at least one lower via; and an intermediate keeper plate comprising a third substantially planar substrate having at least one electrically conductive pivot bar disposed in an at least a first channel located in the third substantially planar substrate, the at least one electrically conductive pivot bar attached to the third substantially planar substrate by an elastomeric material disposed in the at least a first channel for the at least one conductive pivot bar to move in the at least a first channel in response to a force placed thereupon.
