Quality Experiences in Aerospace Electronic Assembly

Abstract

Quality of the electronic assembly depends largely on good quality practices (GQP) adopted
during the process of electronic assembly. Quality experiences gained during working at
the defence and space laboratories have been used to develop good quality practices such as
three- tray method for cleaning of PCBs, use of grommets for cable routing, use of eye-pieceless
stereo zoom microscope for visual testinglinspection, pre-tinning of components, desiccators
for storage, potting prior to conformal coating, continuity and isolation checks, de-golding of
leads prior to soldering, and use of flux-cored solder wire. The paper also discusses how and
why these good quality practices were evolved.
