Abstract:
A package design is provided where a chip module is connected to a printed circuit board (PCB) via a land grid array (LGA) on the top surface of the PCB, and where a power supply is connected to the PCB via a second LGA on the bottom surface of the PCB. The stack of the chip module, power supply, and LGA is held in place and compressed with actuation hardware forming an adjustable frame. The package allows field replacibility of either the module, or the PS, and provides the shortest possible wiring distance from the PS to the module leading to higher performance.
