COMPLIANT PRESSURE LID FOR PROCESSOR SOCKET HARDWARE

Compliant lids for processor socket assemblies are described. The compliant lids described herein ensure uniform compression across the contact field notwithstanding the recent trend to continue to increase the physical dimension of the socket and the density of contacts. Compression uniformity can be enhanced by relocating the pressure exerted on the package away from the corners of the package. This can be accomplished by designing the compliant lids to have openings shaped to interrupt the continuous material that would otherwise extend from the corner of the lid to the region where the lid engages the processor. This void of material is shaped so that continual presence of material exists primarily in the region where the force delivery is preferred. Use of such compliant lids can enhance compression uniformity without having to rely on complex curved plates and stepped insulators.
