ABSTRACT:
A method for minimizing thermal overhead in an integrated circuit package is described. A heat sink having a base is integrally formed into the package. The base is connected to the die, and a portion of the heat sink projects from the package, forming a post. A heat transfer assembly having a shaft with an aperture is heated until the aperture expands sufficiently to allow the heat transfer assembly to be fitted on the post with a minimum of force. Upon cooling, a tight joint is formed between the heat sink and the heat transfer assembly.
