Abstract:
A heat dissipating device for removing heat from an electronic device package, comprising:a semiconductor socket;a semiconductor package installed in said socket; said semiconductor package having a lower surface with electrical contacts thereon; said electrical contacts being in electrical communication with said semiconductor socket; said semiconductor package including an outer peripheral region of said semiconductor package and a first upper surface and an inner pad region of said semiconductor package and a second upper surface;a retaining clip, having a central member and a pair of legs depending downwardly from respective opposing ends of said central member with ends of said pair of legs not connected to said central member being free ends, an aperture disposed through said central member defining a central member bore; female threading formed in said central member bore; means for securing said free ends of said pair of legs relative to said semiconductor socket; said central member bore being positioned substantially above said semiconductor package;a collar having an outer edge defining male threading thereon; said collar defining a collar bore therethrough having female threading thereon; said collar being threadably installable into said central member of said retaining clip with said male threading of said collar being threadably engageable with said female threading in said central member bore; said collar being threadably rotatable within said central member bore and positionable into communication with said first upper surface of said semiconductor package at a desired outer peripheral pressure;a heat dissipating member having a threaded base portion with a substantially flat bottom surface adapted to be threadably received in said female threaded collar bore so that said flat bottom surface of said heat dissipating member is in flush thermal communication with said second upper surface of said semiconductor package at said inner pad region; said heat dissipating member, and threaded routing into said threaded bore, defining an inner pad region pressure onto said second surface of said semiconductor package;whereby said outer peripheral region pressure and said inner pad region pressure are independently selectable.
