In one embodiment, a liquid immersion cooled multichip module is provided which includes a substrate having chips mounted thereon and which is adapted to mount with a printed circuit board. A lid is adapted to secure to the printed circuit board so as to mount with the substrate to form a fluid chamber between the lid and the substrate, and to cause the substrate to mate with the printed circuit board. In one embodiment, a cambered bolster plate is located on a side of the printed circuit board opposite the lid and the lid is fastened to the bolster plate to secure the lid to the printed circuit board. A baffle, which may be removable in some embodiments, is located within the lid and directs coolant flow through the fluid chamber.
