Abstract
A method and apparatus improve the thermal interface between a heat sink and a semiconductor. A support member is attached to a bias plate to facilitate a fixed connection with a surface. The bias plate has a beam for alignment with a heat sink that is attached to the semiconductor. The bias plate is attached to the support member such that the support member forces the beam against the heat sink to improve the thermal interface between the heat sink and the semiconductor. In the method, a heat sink is attached to a semiconductor, and a pivoting beam is biased against the heat sink such that the thermal interface with the semiconductor is improved.
Claims16
An apparatus to improve the thermal interface between a heat sink and a semiconductor, comprising:
- a support member to facilitate a connection with a surface;
- and
- a bias plate including a beam for alignment with a heat sink which is attached to a semiconductor, said bias plate being attached to said support member, a portion of said beam being detached from said bias plate, said beam having a sloped member attached to a contact member, at least a portion of said contact member being detached from said bias plate such that an end of said contact member is free, at least a portion of said contact member to contact said heat sink, such that said support member forces said contact member against said heat sink to improve the thermal interface between said heat sink and said semiconductor.
An apparatus to improve the thermal interface between a heat sink and a semiconductor, comprising:
- a support member to facilitate a connection with a surface;
- and
- a bias plate including a beam for alignment with a heat sink which is attached to a semiconductor, said bias plate being attached to said support member, a portion of said beam being detached from said bias plate, said beam having a first beam end and a second beam end, said first beam end being attached to said bias plate at a bias plate pivot point, said bias plate also including a lateral support member, said first beam end being attached to said lateral support member at said bias plate pivot point, said beam also having a contact member, at least a portion of said contact member being detached from said bias plate such that an end of said contact member is free, at least a portion of said contact member to contact said heat sink, such that said support member forces said contact member against said heat sink to improve the thermal interface between said heat sink and said semiconductor.
A computer comprising:
- a circuit board;
- a semiconductor attached to said circuit board;
- a heat sink attached to said semiconductor;
- a support member attached to said circuit board;
- and
- a bias plate attached to said support member, said bias plate including a beam for alignment with said heat sink, a portion of said beam being detached from said bias plate, said bias plate being positioned such that said beam is forced against said heat sink to improve the thermal interface between said heat sink and said semiconductor.
