CALIPSO Avalanche Photodiode (APD) Detector Assembly Electrical Failure

The APD detector assembly failed during the Satellite Thermal/Vacuum test due to design-drawing error. The design-drawing error indicated reversed installation of a polarized capacitor. The assembly quality assurance (QA) did not detect the error because the assembly matched the drawing. Make certain that QA is involved at every stage including drawing reviews to aid in systems successfully built, tested, integrated and flown at minimum cost.
