Patent ID: 7355854

Claim:
Apparatus for enhanced grounding of transistors, comprising: a printed wiring board having a first surface, a second surface spaced from said first surface and at least one cut-out adapted to receive a transistor, said at least one cut-out extending between said first and second surfaces forming an edge which is at least partially covered with a conductive material, said printed wiring board being formed with a number of vias extending between said first and second surfaces, each of said vias being exposed along said edge of said cut-out; and a heat sink element comprising: (i) a base having a first surface adapted to connect to a heat sink floor and a second surface opposite said first surface, said second surface having a peripheral edge; and (ii) a boss extending outwardly from said second surface of said base, said boss having a perimeter, a shoulder being formed along said second surface of said base between said perimeter of said boss and said peripheral edge of said second surface, said edge of said cut-out and one end of said vias resting on said shoulder, said cut-out being adapted to receive a transistor which is adapted to mount to said boss.
