Abstract
A fastening assembly used for securing a heat dissipation device to a printed circuit board, comprises a sleeve, an inserting device extending through the sleeve, a spring encircling the inserting device and received in the sleeve, and a supporting device inserted in the sleeve. The inserting device engages with a back plate below the printed circuit board. The sleeve is integrally formed of plastic and comprises a hollow body, a resilient portion extending from an outer surface of the body and pressing a bottom of the heat dissipation device upwardly, and four supporting portions extending from the outer surface of the body and pressing a top of the heat dissipation device downwardly. The supporting device is inserted between the body and the resilient portion, and abuts against the resilient portion, to thereby reliably keep the resilient portion at its locked position.
