Advanced polymers on metal printed wiring board

Claim 1

A printed wiring board having a top and bottom surface, said surfaces having a plurality of mounting pads, said printed wiring board further including: a central, substantially rigid core having a top face and a bottom face, said core substantially comprising a composite material clad with an electrically conductive metal, said core having at least one conductive through-hole, said through-hole being electrically insulated with respect to said core; a first insulative layer formed over the top face; a second insulative layer formed over the bottom face; a plurality of conductive and insulative layers overlying the first insulative layer; a plurality of alternating conductive and insulative layers overlying the second insulative layer, said through-hole being electrically coupled to a first conductive region overlying said top face and to a second electrically conductive region overlying said bottom face, selected portions of said patterned conductive layers being electrically coupled to said first and second conductive regions by conductive vias extending through said first and second insulating layers; and selected ones of said mounting pads on said top and bottom surfaces being electrically coupled to said selected portions of said patterned conductive layers whereby an electrical interconnect extends through said rigid core from said top surface to said bottom surface.
