A heat spreader for high volume manufacturing of a heat source, having a heat spreader composition which comprises a heat spreader material, an adhesive thereon, and a release material. The adhesive and release material are selected to prevent delamination of the heat spreader material when the release material is removed during the high volume manufacturing process of heat sources.
