摘要

A heat spreader-package assembly is provided having a heat spreader mounted to a package board with an adhesive. The heat spreader has an upper portion and a plurality of sidewalls extending from the upper portion. The heat spreader has a flange that extends from the sidewalls continuously about a periphery of the upper portion and has a plurality of holes. The holes allow the uncured adhesive to flow therethrough. When the adhesive has cured, a head is formed from the adhesive on an upper side of the flange to establish a riveted connection.
