Abstract:
1. An apparatus comprising: a dielectric substrate having a hole that is open on a side of the substrate; a thermally conductive coating within the hole; a solid body of thermally formable, electrically conductive filling material within the hole in thermal communication with the coating; a heat transfer pad located on the side of the substrate in a position spaced from the hole and the filling material; a thermally conductive structure extending over the side of the substrate from the heat transfer pad to the coating within the hole to provide a conduit for conducting thermal energy from the heat transfer pad to the solid body of filling material in the hole; and a dielectric material positioned over the thermally conductive structure in a configuration interposed between the heat transfer pad and the solid body of filling material as a barrier to the flow of molten material from the heat transfer pad to the filling material.
