Abstract
Numerous embodiments of a heat spreader, comprised of a plurality of downset legs, which provides a simple and lower cost method of forming a heat spreader as compared to conventional methods are disclosed, as well as novel apparatus and methods for attaching the heat spreader to a substrate and a secondary device to the heat spreader, are disclosed.
Claims25
A heat spreader comprising:
- a body having a top surface, a bottom surface, at least one side and at least one corner;
- a plurality of downset legs formed thereon, wherein the plurality of downset legs are formed to be downset from the body bottom surface by a distance, wherein the plurality of downset legs and the body bottom surface define a cavity;
- and
- at least one notch formed between the top surface and the bottom surface proximate to the at least one corner.
