Abstract
Abstract A resilient heat sink clip has a pair of legs joined together at one end by an acruate member. The other ends of the legs each terminate in a hook. The arcuate member bears against a heat sink while pressing it into thermal contact with an electronic device package to conduct heat into the heat sink and then into the atmosphere.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
87 words
Apparatus mounting a heat sink on an electronic device package having a plurality of leads connected through a socket mounted on a printed circuit board, to the printed circuit board comprising: (a) a clip having a pair of legs spaced apart at their first ends by a contiguous connecting member, the member being pressed against the heat sink; and (b) aperatures in the printed circuit board, receiving and securing the second ends of the legs to provide a firm force by the member against the heat sink.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
38 words
The apparatus of claim 1 wherein at least a portion of the member is arcuately shaped, with the apex of the arc bearing against the heat sink, to aid in providing a firm force to the heat sink.
Claim 4
Dependent Claim
34 words
The apparatus of claim 2 wherein the second ends of each of the legs are shaped as hooks and anchor on the underside of the printed circuit board through the pair of apertures, respectively.
Claim 5
Dependent Claim
39 words
The apparatus of claim 3 wherein each of the pair of legs extends at an angle exceeding a right angle with respect to the connecting member to exert pressure against the sides of each of the pair of apertures.
