Method of making a compliant printed circuit peripheral lead semiconductor test socket
First Claim
1. A method of making a test socket comprising the steps of:
- forming a compliant printed circuit comprising the steps of;
printing a first base layer of a dielectric material onto a surface of a fixture;
plating a conductive material into a plurality of cavities in the fixture;
processing the conductive material to form a plurality of first contact members positioned along a first major surface of the compliant printed circuit;
printing a compliant layer on the first base layer;
forming a plurality of conductive traces on an exposed surface of the compliant layer and electrically coupling the plurality of the conductive traces with a one or more of the plurality of first contact members;
printing a plurality of second contact members positioned along a second major surface of the compliant printed circuit and electrically coupling one or more of the second contact members to the conduct traces;
removing the compliant printed circuit from the fixture; and
positioning the compliant printed circuit in a socket housing so the first contact members are located in a recess of the socket housing, so that the compliant layer biases the first contact members into the recess.

Abstract
A test socket that provides a temporary interconnect between terminals on an integrated circuit (IC) device and contact pads on a test printed circuit board (PCB). The test socket includes a compliant printed circuit and a socket housing. The compliant printed circuit includes at least one compliant layer, a plurality of first contact members located along a first major surface, a plurality of second contact members located along a second major surface, and a plurality of conductive traces electrically coupling the first and second contact members. The compliant layer is positioned to bias the first contact members against the terminals on the IC device and the second contact members against contact pads on the test PCB. The socket housing is coupled to the compliant printed circuit so the first contact members are positioned in a recess of the socket housing sized to receive the IC device.
