Abstract :
The characterization of connector failures by scanning electron microscopy/energy dispersive X-ray (SEM/EDX) is described. The advantages of SEM/EDX over optical inspection are discussed. Three types of failures are covered: (1) migration of base metal to the surface, leading to corrosion at the contact area; and (2) fretting corrosion; (3) microcracking at the surface or at a barrier layer, exposing the base metal
