Heat sink with precompressed bias member

摘要

A subassembly of an apparatus, in one example, includes a first body member and a bias member. A fastener extending through the subassembly applies a compression force to the subassembly. A precompression member is engageable with the subassembly and the bias member so as to impart a precompression force to the bias member. In one example, the fastener is a screw engageable with a threaded plate and biased by a leaf spring which is precompressed to facilitate initial engagement of the screw and the threaded plate.
