Abstract
A method of forming a member for joining to form a composite wiring board. The member includes a dielectric substrate. Adhesive tape is applied to at least one face of said substrate. At least one opening is formed through the substrate extending from one face to the other and through each adhesive tape. An electrically conductive material is dispensed in each of the openings and partially cured. The adhesive tape is removed to allow a nub of the conductive material to extend above the substrate face to form a wiring structure with other elements.
