Abstract: A mounting a heat sink (60) in a mounting frame (80) includes two clips (20) and an operating body (40). Each clip has a central portion (22) and two arms (24) depending from opposite ends of the central portion respectively. Two hooks (28) extend inwardly from a distal end of each arm. The operating body includes a main beam (42), two pressing tabs (44) formed from upper edges of opposite ends of the main beam respectively, and two ears (48) extending coplanarly outwardly from bottom portions of the opposite ends of the main beam respectively. When the pressing tabs are depressed, they drive adjacent arms of the clips to move downwardly until the hooks of said adjacent arms are snappingly engaged in corresponding retaining holes of the mounting frame. Thus the clips press the heat sink to firmly contact an electronic package within the mounting frame.

Abstract: A heat sink assembly for an electrical socket of the present invention comprises a heat sink and a latching member latching with a pair of lugs on the socket. The heat sink comprises a base plate and a plurality of fins projecting upward therefrom. A receiving channel is integrally formed between the fins in the base plate for receiving the latching member. A pair of positioning tabs depends downward from a bottom surface of the base plate to tightly engage in a slit between the electric socket and a CPU mounted thereon for positioning the heat sink assembly on the CPU and keeping it from moving along the CPU. The receiving channel and the fins extend in a first direction while the tabs extend in a second direction vertical to the first direction.

Abstract: A method for forming a folded fin includes at least the following steps: providing a horizontal metallic strip; forming number of pairs of indents alternately in a top face and a bottom face of the strip; clamping the strip with three folding tools, wherein a first tool is located between a first pair of indents in the top face of the strip, a second tool is located between a successive second pair of indents in the bottom face of the strip and a third tool is located between a fuirther successive third pair of indents in the top face of the strip; and moving the second and third tools toward the first tool to a position where parts of the strip between the first and second tools and between the second and third tools are bent to be vertical, wherein the third tool moves horizontally toward the first tool and the second tool moves at an angle toward an upper side of the first tool.
