OPTIMIZED THERMALLY CONDUCTIVE PLATE AND ATTACHMENT METHOD FOR ENHANCED THERMAL PERFORMANCE AND RELIABILITY OF FLIP CHIP ORGANIC PACKAGES
摘要:
Disclosed are thermally conductive plates. Each plate is configured such that a uniform adhesive-filled gap may be achieved between the plate and a heat generating structure when the plate is bonded to the heat generating structure and subjected to a temperature within a predetermined temperature range that causes the heat generating structure to warp. Additionally, this disclosure presents the associated methods of forming the plates and of bonding the plates to a heat generating structure. In one embodiment the plate is curved and modeled to match the curved surface of a heat generating structure within the predetermined temperature range. In another embodiment the plate is a multi-layer conductive structure that is configured to undergo the same warpage under a thermal load as the heat generating structure. Thus, when the plate is bonded with the heat generating structure it is able to achieve and maintain a uniform adhesive-filled gap at any temperature.
