16. A system for protecting components on a printed circuit board (PCB) comprising:a polycarbonate sheet, the polycarbonate sheet being formed to match a gross contour of a number of components coupled to the PCB; and
wherein the polycarbonate sheet attaches via interference fit at a slope relative to the PCB; and
wherein the polycarbonate sheet further comprises:
a field of perforations to facilitate cooling of components on the PCB, the perforations arranged in a regular pattern over a surface of the polycarbonate sheet;
a number of apertures through each of which a respective component on the PCB extends when the polycarbonate sheet is in place as a cover on the PCB.
