ABSTRACT:
A heat sink assembly includes a heat sink having torque bars, the torque bars including lips and guides extending from the lips. A package is located between the heat sink and a circuit board. A heat sink retainer includes riser arms and ends connected to the riser arms, where the ends press against the lips. The riser arms press the guides towards the package and press apertures of the heat sink away from the package. In this manner, the retainer imparts torque on the heat sink which causes the heat sink to impart a downward force on the package. This downward force creates the thermal contact between the heat sink and the package.
