A heat sink assembly (10) includes a heat sink (12) and a wire clip (14). The heat sink includes a base (120) and a plurality of fins (124) mounted on the base. A channel (126) is defined between two neighboring ones of the fins. A pair of points (1250) are punched on one of the fins and received in the channel. The wire clip includes a main body (140), first and second legs (141, 142) extending from opposite ends of the main body. The wire clip intervenes across the points and extends through the channel such that the main body is received in the channel and the first and second legs are located at opposite ends of the channel. Thus, the wire clip is prevented from dropping from the channel in a direction parallel to the channel.

A memory module assembly includes a pair of heat-dissipation plates (10), a printed circuit board (20) sandwiched between the heat-dissipation plates (10), and four clamps (30) for securing the heat-dissipation plates (10) onto opposite sides of the printed circuit board (20). Each clamp includes a connecting portion (32) and a pair of elastic pressing portions (34) extending from opposite free ends of the connecting portion. Each pressing portion has a pair of hooks (342) extending from opposite lateral sides thereof and an engaging portion extending (344) from a free end thereof and clamping on an end of the heat-dissipation plate. The hooks are inserted into openings (18) defined in the heat-dissipation plates and engage with inner surfaces of the heat-dissipation plates.

A memory module assembly includes a printed circuit board (10) having a heat-generating electronic component (50) thereon, a pair of heat-dissipating plates (20) attached on the printed circuit board, and a pair of clamps (30) clamping the heat-dissipating plates and the printed circuit board therebetween. Each heat-dissipating plate includes a pair of supporters (28) and a handle (24) rotatably engaging with the supporters. The heat-dissipating plates are installed on the opposite sides of the printed circuit board by exerting a force to the handles to make them move toward each other wherein the force overcomes the spring force of the clamps.
