Abstract
A heat sink assembly includes a retainer having a body, a finger extending from the body and legs extending from the body. The assembly further includes a heat sink having a base and fins extending from the base, where slits in the fins define a trench. A package which includes an electronic device is located between a circuit board and the heat sink and the retainer holds the heat sink in place. To secure the heat sink with the retainer, the retainer is positioned so that the finger of the retainer is aligned with the trench of the heat sink and the legs of the retainer are aligned to slide around the circuit board. The retainer is then moved to slide the finger into the trench and the legs around the circuit board.
