发明名称 Direct chip connection using demountable flip chip package
摘要 The present invention provides an easily reworkable demountable means of electrically interconnecting an integrated circuit die to a substrate. The electrical assembly is comprised of an integrated circuit die having contact areas on a first surface, a substrate having contact areas aligned with the contact areas of the die for providing electrical connection to the integrated circuit die, and a compression means for maintaining the integrated circuit die contacts in electrical communication with the contacts of the substrate. The compression means typically includes a two-part spring system which provides superior electrical contact by causing the curvature of the integrated circuit die to be in the same direction as the curvature of the substrate.
