1. A device, comprising:
a weight optimized stiffener having a top surface, a bottom surface, an outer periphery and an inner periphery forming an aperture through the top and bottom surfaces,
wherein the aperture is adapted to receive a portion of a substrate coupled to the bottom surface of the stiffener by an adhesive; and
a top plate coupled to the top surface of the stiffener;
wherein the stiffener has a plurality of holes corresponding to a plurality of holes in the top plate, each of the plurality of holes in the stiffener forming a pair with a respective one of the plurality of holes in the top plate, each pair of the plurality of holes adapted to receive a portion of a fastener therethrough for coupling the top plate to the stiffener.
