Patent ID: 6927588

Claim:
A testing assembly for testing an electronic ball grid array (BGA) device having an electrical ball connector pattern wherein said BGA device is tested on a test circuit board which includes at least one test circuit having a test connection pattern corresponding to the ball connector pattern of said BGA device, wherein said assembly comprises: a test circuit board having at least one test circuit with a plurality of terminal contacts; a conductive connector pad generally overlying said test circuit to make electrical contact with said terminal contacts of said test circuit; said conductive connector pad having a thickness defined by an upper conductive surface and a lower conductive surface, and said connector pad composed of conductive material so that said connector pad is conductive across its entire thickness; a test casement secured to said circuit board in a test position above said connector pad and said test circuit; a ball alignment plate carried by said casement overlying said connector pad and test circuit having a ball hole pattern corresponding to said ball connector pattern of said BGA device; said test casement having a casement opening through which said ball alignment plate is exposed overlying said connector pad and test circuit; a releasable retainer carried by said test casement for retaining said BGA device on said test casement so that said ball connector pattern of said BGA device is retained in contact with said conductive pad and in alignment with said ball hole pattern of said ball alignment plate for testing; whereby said BGA device circuit is aligned in electrical connection with said test circuit through said conductive pad for reliable testing of said BGA device.
