1. A consolidated thermal module used to uniformly secure electrical contacts of an integrated circuit (IC) to corresponding electrical contacts of an electrical connector disposed on a first surface of a printed circuit board (PCB) and to maintain the IC in uniform thermal contact with a heat transfer assembly, the consolidated thermal module positioned at a second surface of the PCB, the second surface opposite the first surface, the consolidated thermal module comprising:

  • a stiffener plate disposed on the second surface of the PCB;

    a retaining mechanism in mechanical contact with the stiffener plate and disposed on the second surface of the PCB and comprising;

    a first spring assembly capable of generating a first retaining force and secured to the IC and the heat transfer assembly by first fasteners symmetrically disposed about first midpoint of the first spring assembly such that the first retaining force is uniformly applied to the first fasteners, anda second spring assembly capable of generating a second retaining force and in uniform and direct mechanical contact with the stiffener plate and secured to the IC and the heat transfer assembly by second fasteners symmetrically disposed about a second midpoint of the second spring assembly such that the second retaining force is uniformly applied to the second fasteners and wherein the first and second spring assemblies communicate with each other by way of a transverse member at a midline of the retaining mechanism such that the first and second retaining forces are applied uniformly to the stiffener plate.
