Failure Analysis of PCBAs

Printed Circuit Board Assemblies (PCBAs)

 

Common causes of PCBA failures include component failures, PTH via opens, electromigration, corrosion, black-pad-syndrome, thermal fatigue, mechanical overstress, and more.

Failures seen in printed circuit board assemblies (PCBAs) are shown below.
