Abstract: A system for electrically connecting two sets of conductive pads or contacts. The system includes an interposer having conductive bumps on each of two opposing surfaces, with each bump on one surface being electrically connected by a conductive via to a corresponding bump on the opposing surface. The connector system acts to maintain electrical contact between each set of bumps and a corresponding set of conductive pads, thereby electrically connecting the two sets of pads. The bumps on each surface of the interposer are deformable and are placed into physical contact with the corresponding set of pads. The bumps and pads are maintained in good electrical contact by the force supplied by a clamping spring, which causes the bumps to deform until the contact area between a bump and a pad is sufficiently large to reduce the resistance between the bump and pad to a desired value.
