Compliant printed circuit socket diagnostic tool

A diagnostic system for testing integrated circuit (IC) devices adapted to couple to a printed circuit board (PCB) by a socket, the diagnostic system comprising:

• a first diagnostic tool adapted to be located at a first interface between the socket and the PCB, the first diagnostic tool comprising;
• a first compliant printed circuit comprising a plurality of contact pads configured to form an electrical interconnect at the first interface at proximal ends of contact members in the socket and contact pads on the PCB;
• a plurality of printed conductive traces electrically coupled to a plurality of the contact pads on the first compliant printed circuit;
• and
• a plurality of electrical devices printed on the first compliant printed circuit at a position external to the first interface, the electrical devices electrically coupled to the conductive traces and programmed to provide one or more of continuity testing at the first interface or functionality testing of IC devices located in the socket.

A method of making a first diagnostic tool for testing integrated circuit (IC) devices adapted to couple to a printed circuit board (PCB) by a socket, the method comprising the steps of:

• printing a plurality of contact pads on a first compliant printed circuit, the contact pads configured to form an electrical interconnect at a first interface between proximal ends of contact members in the socket and contact pads on the PCB;
• printing a plurality of conductive traces electrically coupled to a plurality of the contact pads on the first compliant printed circuit;
• printing a plurality of electrical devices on the first compliant printed circuit at a location external to the first interface so that the electrical devices are electrically coupled to the conductive traces;
• positioning the first compliant printed circuit between the socket and the PCB to form an electrical interconnect at the first interface;
• and
• evaluating one or more of continuity at the first interface or functionality of one or more IC devices located in the socket.
