Conductive anodic filament (CAF) susceptibility of printed wiring boards (PWBs)

Since 1970s, researchers identified a new catastrophic failure mode called CAF in PWBs. Today, the study of CAF becomes very important as a result of the increased wiring density, the use of halogen-free retardants, and the demands for better performance in the hostile environment for electronic devices.

My first objective of the research is to evaluate the CAF susceptibility of PWBs containing halogen-free flame retardants and different curing agents such as dicyandiamide (DICY), phenolic, and traditional bromide. The second objective is to study the effects of test structures such as hole-to-hole, micro-via to micro-via, and power plan to hole on CAF formation.
