ABSTRACT:
An electrical interface connects a conductive pins to a printed circuit board. The electrical interface includes an elastomer holder having a plurality of holes. Elastomer conductors are placed in the plurality of holes within the elastomer holder. The elastomer holder is then attached to the printed circuit board so that each elastomer conductor comes into contact with a conductive pad on the printed circuit board. The conductive pins are placed in electrical contact with the elastomer conductors, for example, through a conductive socket. In the preferred embodiment the elastomer holder is composed of printed circuit board material. Before the elastomer holder is connected to the printed circuit board, the elastomer conductors are held in the holes in the elastomer holder using a throw-away retainer.
