This paper describes a method of supporting commercially available motherboards, backplanes and daughter cards in rugged environments. These commercial off the shelf (COTS) Printed Circuit Boards (PCBs) such as motherboards, backplanes and daughter cards are usually supported away from a parallel surface by standoffs attached to either mounting holes or edges. These standoffs are not always located in the best locations to protect the COTS PCBs from experiencing damaging deflec- tion due to shock or vibration loads in rugged envi- ronments. The support mechanism described in this paper solves damaging deflection problem and still allows simple assembly and disassembly of the COTS PCBs from the parallel surface. This support mechanism is important because more and more COTS PCBs are being used in equipment which is being designed for severe environments such as mi- itary, aerospace and industrial applications.
