Patent ID: 7452212

Claim:
An electrical connecting device, comprising: an electrically insulating carrier; and one or more contact structures traversing a plane of the carrier, each of the one or more contact structures comprising an elastomeric material having an electrically conductive layer running along at least one surface thereof continuously through the plane of the carrier, the elastomeric material forming elastomeric bumps on opposing surfaces of the carrier; wherein the carrier comprises one or more openings adapted to permit at least one of the elastomeric material and the electrically conductive layer to traverse the plane of the carrier, and wherein at least one of the one or more contact structures further comprises: an insulating layer formed on at least a portion of the electrically conductive layer, the insulating layer running continuously through the plane of the carrier; and a second electrically conductive layer formed on at least a portion of the insulating layer, the second electrically conductive layer running continuously through the plane of the carrier.
