Patent ID: 7271581

Claim:
A printed circuit board, comprising: a plurality of active test contacts each configured for coupling with a corresponding plurality of pins on an integrated circuit device, including: a plurality of active contact pads on a first conductive side configured for coupling with the plurality of pins on the integrated circuit device; and a plurality of active test pads on an opposing second conductive side configured for coupling with test equipment, the plurality of active contact pads and the plurality of active test pads respectively electrically coupled with a corresponding plurality of conductive active contact vias; and at least one inactive test contact electrically isolated from the plurality of active test contacts and configured adjacent to at least one of the plurality of active test contacts, the at least one inactive test contact including: an inactive contact pad on the first conductive side; an inactive test pad on the second conductive side, the inactive contact pad and the inactive test pad electrically coupled with a conductive inactive contact via and the at least one inactive test contact electrically coupled to an electrical reference signal on the printed circuit board.
