ABSTRACT:
A printed-circuit-type electrical contact pad having a plurality of electrically conductive metal traces and a plurality of protuberant electrical contacts projecting from the traces. The protuberances comprise an electrically conductive elastomer having a wide base portion anchored in the end of the trace by a truncated portion of the trace upstanding from the face of the pad. A denuded tip portion of the elastomer extends from the base portion for resiliently engaging a contact site on an electrical device to which the pad is coupled. A unique process for making the aforesaid pad is disclosed and claimed.
