ABSTRACT:
Pads which are attached to a high density printed circuit board (PCB) having a plurality of through-holes opening on the top surface. A plurality of pads are formed on a carrier sheet so that each of the pads have a copper layer proximate to the carrier sheet and a joining metal layer formed on top of said copper layer. The plurality of pads are positioned on the carrier sheet so that they are aligned with the through-hole pattern on the top surface of the PCB, the pads bing laminated to the through-holes on the top surface using the joining metal, and the carrier sheet being separated from the plurality of pads that are joined to the through-holes so that the copper layer is exposed. The pads may possess a variety of shapes such as disk-shaped, elongated, or rectangular, and can cover one or multiple through-holes. An electrical component may be soldered to the pad. The pad and through-hole may be compressed so that the top surface of the pad is even (flush) with the top surface of an external dielectric surface.
