ABSTRACT:
A clip for fastening a heat sink to a CPU mounted on a ZIF connector is made by stamping a metal sheet. The clip has an elongated body portion for pressing the heat sink toward the CPU. A first arm extends downward from a first end of the body portion and defines a hole about its free end for fitting with a first lug of the connector. A second arm extends downward from a second end of the body portion and defines a hole about its free end for fitting with a second lug of the connector. A handle portion is formed by plastic injection molding to be fixed to upper end of the second arm. The handle portion is used for receiving a manipulating force of the clip exerted directly by fingers of an operator. A pair of tabs integrally formed with the second arm is located below the handle portion and projects toward each other. A tool may be used to extend to abut the tabs via the handle portion, whereby the manipulating force of the clip may be exerted to the clip through the tool.
