Abstract: A clip for clamping a heat sink and a semiconductor chip together on a main board of a computer is disclosed, in which a semiconductor chip such as a CPU of a computer is coupled with a heat sink by means of the clamping clip, for releasing the generated heat of the semiconductor chip. Particularly, a clip for clamping a heat sink and a semiconductor chip together on a main board of a computer is disclosed, in which a fixing clip having left and right bent segments is used, and the heat sink is elastically fixed to the main board of a computer by means of the clamping clip, so that an external impact cannot cause the heat sink to detach from the main board of the computer. Thus a single clip is used in elastically fixing the heat sink and the semiconductor chip to the main board in an easy manner, that is, four pins protruding to under the bottom of the main board are fixed by means of a single clip, thereby realizing a sure and firm fixing.
