Abstract
Method and assembly for attaching a heat sink to a heat source surface associated with a printed circuit board or other component having a heat source. A fastener assembly may include a push pin with a barbed, bifurcated end arranged to be inserted through an opening of the printed circuit board and thereby secure the heat sink to the printed circuit board. A stopper may be headless, be separable from the push pin, and have a portion, such as a barrel-shaped element, positionable in a throughbore of the push pin that supports the bifurcated end so that movement of the barbed portions toward each other is resisted, thereby securing engagement of the barbed portions with the printed circuit board.
