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.
