Abstract
A circuit board is fabricated from first and second composite sheets, each composed of a substrate of dielectric material and at least one conductor run adhered to the substrate. The substrate of the second composite sheet is formed with a through hole adjacent to the conductor run of that sheet. The second composite sheet is adhered to the first composite sheet, with the conductor run of the first sheet exposed through the hole in the second sheet. Conductive material is introduced into the hole and provides an electrically-conductive connection between the conductor runs of the two sheets.
