Abstract:
1. A retention mechanism for mounting an integrated circuit package to a circuit board, comprising: a dish-shaped elastically deformable pressure plate, having a first apex and a first periphery spaced away from the first apex, the pressure plate being deformable by applying a first force to the first periphery directed generally towards the first apex; a dish-shaped elastically deformable backing plate, having a second apex and a second periphery spaced away from the second apex, the backing plate being deformable by applying a second force to the second periphery directed generally towards the second apex, wherein the backing plate is in contact with the circuit board, wherein the circuit board has a back side, and wherein the second periphery is to enable a plurality of components to be attached to the back side of the circuit board, after the integrated circuit package has been mounted to the circuit board; and means for simultaneously applying the first and second deforming forces to the first and second peripheries to engage the first apex with a surface of the integrated circuit package and the second apex with a surface of the circuit board so as to effect continuous electrical continuity between the integrated circuit package and the circuit board.
