Abstract
An integrated heat sink that can provide heat dissipation from multiple components mounted on a circuit board with each component having a different height dimension relative to each other is described. The heat sink has a first face on which a plurality of cooling fins are formed and a second face on which at least one pedestal is formed. The pedestal has a contacting surface to thermally couple to at least one of the multiple components to dissipate heat therefrom. The heat sink is designed to prevent a junction temperature at the contact area where the heat sink and each of the components abut one another from exceeding a maximum design value for the system. In one embodiment of the present invention, the heat sink has a groove formed in the second face. A conductive gasket is disposed in the groove and contacts a metal trace on the circuit board when the heat sink is attached to the circuit board to form a Faraday cage or EMI shield.
