COMPLIANT S-LEADS FOR CHIP CARRIERS ABSTRACT OF THE DISCLOSURE A compliant S-shaped lead for resiliently supporting an integrated circuit chip package in spaced relation generally parallel to a printed circuit board. The S-lead bends and twists to absorb forces which would otherwise be exerted on solder joints due to temperature cycling and vibration. The symmetrical S-lead self-centers on both the package and PC board to provide minimum stress. The leads are held by a support strip for connection to the chip carrier. Thereafter, the support strip is removed and the carrier positions the leads for connection to the circuit board. e7297G-4
