A connector for attaching a heat sink or other device to a circuit board comprising an attachment portion for connecting to the device, the attachment portion having a pair of legs, each with a projection on its end, the legs being spring-biased so that once the projections pass through the hole, the projections expand and engage the surface of the board or edges of the holes opposite the device.

Self-locking tab

A heat sink in adapted to be attached to a pin grid array comprising a pair of grooves extending along opposite sides into which grooves the tops of attachment clips are disposed. The heat sink has a pair of indentations on opposite sides of each clip holds each clip in place in the groove, the heat sink with the clips attached being positioned between two compression sections of a pair of attachment pliers and when a pin grid array is positioned adjacent to the heat sink, compression of the plier handles connects the clips to the pin grid array. Removal is accomplished by a pair of pliers having projecting points which fit beneath the clips so that compression of the plier handles forces the clip away from the pin grid array disconnecting it.

Heat sink for an electronic pin grid array

A clip for attaching a semiconductor to a heat sink comprises an arcuate section having a lip which contacts a projection on a heat sink so that the remainder of the arcuate section is disposed over the projection, the arcuate section also having a central stiffening rib. The clip further comprises a plate extending from the end of the arcuate section opposite its lip, the plate having sidewalls which form a semiconductor opening. When the clip is in place on the heat sink, the clip is flexed, and the plate is forced against a semiconductor, holding it in place against the heat sink.
