Patent ID: 7518875

Claim:
A method comprising: inserting first and second retention features through separate openings in a circuit board from a first side of the circuit board to a second side of the circuit board until the first and second retention features are accessible on the second side of the circuit board on opposing sides of a heat generating device, wherein the first and second retention features are secured to a common base that remains on the first side of the circuit board, and wherein each retention feature includes a pivot groove and a retention ramp; positioning a heat sink having a heat sink base and first and second levers pivotally secured to opposing sides of the heat sink base so that the first and second levers are aligned with the first and second retention features, each lever having a spring clip with first and second arms; receiving the first arm of each spring clip in one of the pivot grooves; and pivoting the first and second levers to cause the second arm of each spring clip to engage one of the retention ramps and secure the heat sink base to the first and second retention features with the heat sink base in contact with the heat generating device, wherein the common base and the heat sink are secured with the circuit board and the heat-generating device there between.
