Abstract
A readily attachable and detachable heat sink assembly apparatus and method. In one embodiment of the present invention, a backing plate has alignment pins extending therefrom. The backing plate is adapted to be located next to the back surface of a printed circuit board, and have the alignment pins extend through the holes in the printed circuit board. A heat sink unit is adapted to thermally contact a heat generating device located on a front surface of the printed circuit board. The heat sink unit also has holes formed therethrough which are adapted to allow the alignment pins of the backing plate extend through the heat sink unit. A clasp plate is adapted to be located on top of the heat sink unit and has slits which are configured to grasp the ends of the alignment pins. A fastener coupled to the clasp plate fastener is adapted to release the heat sink unit from the heat generating device or tightly attach the heat sink unit to the heat generating device. In so doing, the heat sink unit can be attached to or detached from the heat generating device without having to have access to the back surface of the printed circuit board.
