Abstract:
A heat sink assembly for removing heat from multiple semiconductor device packages, comprising:a circuit board;a first semiconductor device package installed on said circuit board; said first semiconductor package having a lower surface with electrical contacts thereon; said electrical contacts being in electrical communication with said circuit board; said first semiconductor package including an outer peripheral region and an upper surface;a second semiconductor device package installed on said circuit board; said second semiconductor package having a lower surface with electrical contacts thereon; said electrical contacts being in electrical communication with said circuit board; said second semiconductor package including an outer peripheral region and an upper surface;a support plate; said support plate being positioned over said upper surface of said first semiconductor device and over said upper surface of said second semiconductor device; said support plate defining a first threaded bore, having a diameter, substantially aligned with said first semiconductor device and said support plate defining a second threaded bore substantially, having a diameter, aligned with said second semiconductor device;means for securing said support plate to relative to said first semiconductor device and said second semiconductor device; said means for securing said support plate to relative to said first semiconductor device and said second semiconductor device being a downwardly depending leg with a inwardly directed lip into communication with said outer peripheral portion of said first semiconductor device and at least one threaded fastener secured through said support plate and into communication with respective at least one female threaded apertures in said upper surface of said second semiconductor device package;a first heat dissipating member having a threaded base portion, having a diameter, with a substantially flat bottom surface adapted to be threadably received in said first threaded bore so that said flat bottom surface of said first heat dissipating member is in flush thermal communication with the upper surface of said first semiconductor package; anda second heat dissipating member having a threaded base portion, having a diameter, with a substantially flat bottom surface adapted to be threadably received in said second threaded bore so that said flat bottom surface of said second heat dissipating member is in flush thermal communication with the upper surface of said second semiconductor package.
