Abstract
A printed circuit board heat sink retainer is disclosed comprising a mating pair of sawtoothed bars with slidably engaging teeth. The bars are laterally spread apart and held by a forcing device, which may be a screw or a spring, in order to push against and hold a heat sink in a channel. The distance between successive teeth may be constant in both bars or may be constant in one bar and may decrease in a direction toward the forcing device in the second bar.
