Abstract
An assembly for clamping a heat sink to an integrated circuit package that is mounted to printed circuit board. The assembly includes a pair of pin headers that are mounted to the printed circuit board. The assembly also contains a clip that is snapped onto the pin headers and presses the heat sink into the package. The pin headers each have a pair of posts that extend from a spacer. The posts are soldered to the printed circuit board to secure the headers to the board. The headers also have wire loops that extend from the spacers and capture the ends of the clip.
Claims6
An integrated circuit package assembly, comprising:
- a printed circuit board;
- a pair of pin headers mounted to and electrically coupled to said printed circuit board;
- an integrated circuit package mounted to said printed circuit board;
- a heat sink located on said integrated circuit package;
- and,
- a clip that is attached to said pin headers and which presses said heat sink into said integrated circuit package, said clip also electrically couples said heat sink to said pin headers and said printed circuit board.
A method for clamping a heat sink to an integrated circuit package, comprising the steps of:
- a) providing a printed circuit board that has an integrated circuit package and a pair of pin headers extending from a top surface of said printed circuit board, wherein said pin headers are electrically coupled to said printed circuit board;
- b) placing a heat sink onto the integrated circuit package,
- c) placing a clip onto said heat sink;
- and,
- d) attaching said clip to said pin headers to press said heat sink into said integrated circuit package and electrically coupling said heat sink to said pin headers and said printed circuit board.
