Heat sink clip

Disclosed is a design for a heat sink clip. Benefits include the assertion of force at a single point sufficient for use with heat sinks designed for 1+ GHz processors.

Components of the disclosed design are a clip, a 6-32 screw, and a captive washer. The purpose of this clip is to supply a force of 40 10 lbs at a specific point on the base of the heat sink centered over the processor. Therefore, the clip supplies force at only one point over the die. The material is C1074 steel hardened and tempered to HRC 43-48 with zinc and clear chromate plating at .053 inch thick.

The single screw design provides ease of installation (see Figures 1-3). To install, slide the keyed feature side of the clip into the post and then screw down the other side with a torque of 10 in-lbs.

A keyed-feature provides mistake-proof orientation of the heat sink. The clip is keyed on one side that attaches to a specific standoff post that is assembled to the chassis independent of the baseboard. The other end of the clip holds a standard screw and captive washer.

The clip holds up to a 300 gram heat sink and pass unpackaged shock test at 40G.
