Abstract:
1. An apparatus, comprising: a substrate having a surface with a plurality of metal pads, wherein the substrate is either a plastic land grid array (PLGA) module carrier or a printed wiring board (PWB); a plurality of preform contacts each respectively soldered to one of the plurality of metal pads and lying entirely on the surface of the substrate with the plurality of metal pads without any portion of the preform contact extending into the substrate, wherein each of the preform contacts comprises a metal preform base having a lower surface attached to one of the plurality of metal pads through a solder layer, wherein each of the preform contacts comprises an electrolytic noble metal plating over the metal preform base, wherein each of the preform contacts is substantially disc-shaped and has a substantially planar top surface and a substantially planar bottom surface that are substantially parallel to each other, wherein the substantially planar top surface of each of the preform contacts is defined by an upper surface of the electrolytic noble metal plating, and wherein the substantially planar bottom surface of each of the preform contacts is defined by the lower surface of the metal preform base and is in physical contact with the solder layer.
