Claim:
1. A method of making a circuit subassembly comprising: in order: placing a plurality of burned-in, packaged components on the substrate top side so that the plurality of burned-in packaged components are each contained within respective ones of the plurality of apertures, each of the plurality of burned-in packaged components having at least one first lead, the at least one first lead contacting the substrate top side; employing a first electrically insulating material to cover the plurality of burned-in packaged components while still permitting said at least one lead to continue to contact said substrate top side, the first electrically insulating material further forming a substantially uniform flat surface spaced from said frame top side, and spanning said plurality of apertures; and laser drilling at least one via through the other side of the substrate to expose the at least one first lead of the burned-in packaged component; and filling the at least one via with an electrically conductive material.
