ELECTRIC CONNECTOR ASSEMBLY BODY INCLUDING DEFORMABLE CONTACT CONNECTOR SUPPORTED BY CONTACT FORCE CLAMP SPRING AND ELECTRIC CONNECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electric connector assembly body that can maintain a good electric connection between a bump and a conductive pad. SOLUTION: The system has interposers 212 in which bumps 214 electrically connected by a conductive pier are installed on both faces. The bumps 214 on both faces of interposers 212 are deformable, and come into a physical contact with a pair of pads corresponding to them. A good electrical contact between the bumps and the pads is maintained by a force applied by using a clamp spring that is capable to add a nearly constant force within the range produced by the displacement of the component of the connector system to the bump-pad boundary surface. The combination of the deformable bumps 214 and the constant force acts to maintain the good electric contact between the bumps and the pads all through the life of the connector.
