Abstract:
1. A heat dissipation structure, comprising: a heat sink comprising a base comprising four securing tabs, each of the four securing tabs laterally extending from each corner of the base and each of the four securing tabs defines a recess; a printed circuit board comprising four positioning posts upwardly projecting from the printed circuit board, in a projected view of the printed circuit board, each of the four securing tabs is adjacent a corresponding one of the four positioning posts; and four spring clips, each of the four spring clips being attached to the corresponding one of the four positioning posts and each of the four spring clips is restricted to be rotated within a limited angle range about the corresponding one of the four positioning posts, wherein each of the four spring clips comprises a resilient piece, wherein when the resilient piece is rotated into the recess of a respective one of the four securing tabs, each of the four spring clips exerts a downward force and presses the respective one of the four securing tabs, thereby securing the heat sink to the printed circuit board.
