Abstract
A fastener for mounting a heat sink to a circuit board. The heat sink has a lower surface, at least one groove in the lower surface defining first and second surfaces extending substantially normal to the lower surface, and a lock recess on each of the first and second surfaces. The circuit board has a plurality of openings in a mounting surface thereof The fastener includes a body having a main portion. A spring clip extends in a first direction from the main portion into the groove and is biased to engage the first and second surfaces of the heat sink. A plurality of latches on the spring clip engage the lock recesses when the spring clip engages the first and second surfaces of the heat sink. A plurality of anchor lugs extend in a second direction from the main portion, opposite the first direction, to be received in respective openings in the board to rigidly attach the fastener to the circuit board. Preferably, the anchor lugs are of differing lengths and configurations to permit assembly of the clip to different sized circuit boards. Also preferably, engagement protrusions on the clip engage a concave surface on the heat sink.
