Electrical interface with microwipe action

U.S. Patent Number: 5338209

Abstract: A circuit interface for an electrical connector having a compressible elastomeric core. The circuit traces on the elastomeric core have a roughened copper foil inner layer, an intermediate metal layer and a gold outer layer in which the intermediate layer and outer layer have asperites which correspond with and complement the roughened surface of the copper inner layer. The asperites abrade and bite through oxidized surfaces of electrical members which are contacted by the circuit traces on the elastomeric core and assure good electrical conductivity for the circuit interface.
