Abstract: A unitary sandwich-type ground and voltage plane consisting of a first and second layer of conductive material separated by an insulator and having therein a plurality of spaced apertures in a pattern to conform to the spacing of connector terminals and having etched patterns on said first and second layers for enabling electrical connections to be made between appropriate terminals and the first and second conductive layers.
