ABSTRACT:
A heat sink assembly to remove heat from electrical components mounted on a circuit board is disclosed. The assembly contains a housing that is formed from a suitable heat sinking material and is appropriate for receiving a circuit board with surface mounted electrical components. The invention provides an improved apparatus for establishing thermal contact from a heat generating, surface mounted electrical component to the housing. A resilient biasing element is fixed in relation to the circuit board and the housing in order to urge the circuit board with a plurality of surface mounted electrical components in thermal contact with the housing. Once the heat sink is assembled the invention provides various means for which heat can be readily transferred from the electrical components to the housing. Heat can be transferred away from the electrical component to the housing through a thermal via incorporated within the circuit board, though the resilient biasing element, or by direct contact of the electrical component and the housing.
