Patent ID: 8567483

Claim:
A heatsink assembly, comprising: a heatsink base having a single base plate, the base plate including oppositely-facing upper and lower surfaces, the base plate including a rigid inner region for direct thermal contact with a heat-generating component and a flexible outer region extending outwardly of the rigid inner region; a plurality of heat sink cooling fins secured directly to the base plate, the plurality of heat sink cooling fins including one or more inner cooling fins traversing the rigid inner region of the base plate and outer cooling fins outwardly spaced from the rigid inner region of the base plate, wherein the outer cooling fins have fin ends located above fin ends of the inner cooling fins when the flexible outer region of the base plate is unflexed; and a plurality of fasteners for securing the base plate to a circuit board at the outer region of the base plate, wherein the plurality of fasteners may be placed in sufficient tension to flex the outer region of the base plate while the rigid inner region remains flat against the heat-generating component, and wherein the fin ends of the outer cooling fins are not located above fin ends of the inner cooling fins when the flexible outer region of the base plate is flexed.
