ABSTRACT:
An adjustable fastening device for integrated circuit chips of varying thicknesses includes a radiating fin, a base plate, a number of resilient cramps and a number of screws. The radiating fin has at least two opposite sides which each include an upper ledge, a lower ledge and a longitudinal recess therebetween. Each upper ledge defines at least one vertical through-hole. Each lower ledge defines at least one recess corresponding to the vertical through-hole. The base has at least two opposite sides from each of which a hook downwardly extends. The cramps corresponding to the hooks have a top portion, a side portion and an arcuate portion extending therebetween. The top portion defines a hole to engagingly receive one of the screws. The side portion defines a slot configured to receive a corresponding hook. An integrated circuit chip is received between the radiating fin and the base. Each screw is extended through the corresponding vertical hole of the radiating fin and tightened such that the integrated circuit chip is firmly retained.
