ABSTRACT:
Connection of electrical leads to individual charge electrodes in a charge plate structure is facilitated by the integral formation of such leads during the mold stage of formation of a charge plate. An elastomeric mold is formed from a charge plate master coated with a photoresist material and having base area corresponding to the placement of the electrical leads. The elastomeric mold is coated with an electrically conductive resin, and a charge plate is cast in the mold. Upon separation, the conductive resin transfers to the charge plate structure forming charge electrodes. Lapping or grinding the surface of the structure removes excess resin and leaves the electrical leads intact.
