Patent ID: 7139174

Claim:
A circuit board module, comprising: a circuit board; a circuit board component mounted to the circuit board; and a heat sink assembly including: a base member which has a first edge and a second edge, the base member being configured to operate as a thermal conduit between a first location proximate to the circuit board component and a second location distal to the circuit board component; a first rail member coupled to the base member along the first edge of the base member and a second rail member coupled to the base member along the second edge of the base member; and an actuation mechanism coupled to the base member, the actuation mechanism being configured to move portions of the first and second rail members toward each other when the base member resides at the first location to fasten the base member to the circuit board component; wherein the base member of the heat sink assembly is rectangular in shape; and wherein the actuation mechanism includes: exactly four screws, each screw being disposed in a corner portion of the base member and being configured to translate linear movement along a respective screw axis into angular displacement of a rail member.
