Patent ID: 8102184

Claim:
A test receptacle ( 30 ) for making temporary electrical contact with a plurality of microcircuit terminals ( 20 ) having a predetermined pattern, comprising: a test contact element array ( 40 ) comprising a plurality of test contact elements ( 56 - 58 ) arranged in substantially the predetermined pattern of the plurality of microcircuit terminals ( 20 ), each test contact element ( 56 - 58 ) in the plurality comprising a resilient finger ( 56 a , 56 b , 57 a , 57 b , 58 a , 58 b ) projecting from an insulating membrane ( 50 ) as a cantilevered beam, and having on a contact side thereof a conducting contact pad ( 63 a , 63 b , 64 a , 64 b , 65 a , 65 b ) for contacting a corresponding microcircuit terminal ( 20 ) in the plurality; a plurality of connection vias ( 83 - 85 ) arranged in substantially the predetermined pattern of the plurality of microcircuit terminals ( 20 ), each connection via ( 83 - 85 ) in the plurality aligned with one of the test contact elements ( 56 - 58 ); an interface membrane ( 80 ) supporting the plurality of connection vias ( 83 - 85 ); wherein at least one of the connection vias ( 83 - 85 ) is cup-shaped with an open end, with the open end of the cup-shaped via ( 83 - 85 ) contacting a corresponding test contact element ( 56 - 58 ).
