Abstract
An installation apparatus and method for actuating the electrical connection of a land grid array module to a printed wiring board is provided. A backside stiffener with load posts is attached to a printed wiring board. A load plate, module, plurality of load columns, and springplate are operably connected to the load posts. An actuation screw operably connected to the springplate is rotated imparting an actuation force to the module. The backside stiffener includes a local stiffener, wherein the local stiffener causes a deflection in the printed wiring board complementary to the deflection of the module when the actuation force is applied.
