ABSTRACT:
A flexible connector cable for providing high density and reliable electrical interconnections between printed circuit boards or any other surfaces having conductive paths that need connection to conductive paths on adjacent surfaces. The connector cable comprises a flat flexible laminar structure including an electrically-insulative layer and an electrically-conductive layer. The insulative layer is typically formed on a bonded plastic such as Polyimide and the conductive layer is typically formed of copper. Openings are formed in the insulative layer to expose the conductive layer and raised contacts or buttons are deposited on the conductive layer on both surfaces of the cable. The raised contacts are formed of ductile conductive material which exhibits plastic deformation under pressure to form good electrical connections.
