Claim Text:
1. An array of composite polymer-metal contact members forming solder free electrical connections with a first circuit member, the contact members comprising: a resilient base layer comprising a continuous sheet of a liquid crystal polymer; at least one polymeric dielectric layer selectively positioned on the polymeric base to form recesses corresponding to a desired circuit trace; a conductive material deposited in at least a portion of the recesses comprising conductive traces surrounded on at least one side by the resilient base layer and on at least two sides by the polymeric dielectric layer, the conductive traces comprising exposed terminals that electrically couple to the first circuit member; and the resilient polymeric base layer, the dielectric material, and the conductive traces comprising an aggregate spring constant maintaining distal portions of the contact members in a cantilevered configuration that flexes to form a stable, solder free electrical connection between the distal portions and the first circuit member solely by compressive engagement.
