Abstract
A porcelain coated steel substrate for receiving thick film printed circuit thereon includes thermally and electrically conductive pedestals which are in thermal and electrical contact with the steel core. The pedestal surface is coplanar with the porcelain coating so that a substantially continuous plane surface is present. This permits semiconductor chips readily to be mounted on the substrate, the pedestals serving as heat and electrical conductors to the substrate, and serves also to facilitate the deposition of thick film elements.
