Abstract

This is study of typical corrosion failure in electronics arose from usual methods as galvanic corrosion, electrochemical migration, and bias induced corrosion. Common metals and alloys used in electronic devices are Al, Au, Cu, Ag, Sn, Pb and alloyed forms. Noble metal plated high performance electrical contacts have descriptive issues as high corrosion resistance thereby stable electrical behaviour. Films of metals and alloys constitutive to chip fabrication has detected to corrode and fail depending on environment and surpassed electrical annotation margins. Moistened contamination has surveyed by infer-red camera photography on printed circuit board assay. Electrified thermal is to cold spot camera photography has justified condensation of contaminated water film images to assess deterioration upon time allowed under intended expose to gaseous and moist weather.
