Abstract:
A heat sink apparatus that provides electrical isolation for an integrally shielded, electronic circuit, which comprises:a substrate having a first hole extending between a first and second sides of the substrate; a conductive layer attached to the second side; an electrically and thermally conductive heat sink having a protrusion, wherein the heat sink is attached to the first side of the substrate, wherein the protrusion extends through the first hole, wherein the protrusion has a surface located at substantially the same level as that of the conductive layer, and wherein an electronic component is attachable to the protrusion surface; and an electrically conductive plate having a second hole extending through the plate, wherein the plate is electrically coupled to the conductive layer and to the protrusion surface such that open space between the protrusion and the conductive layer is covered by electrically conducting area of the plate.
