Failure Analysis of PWBs
Printed Wiring Boards (PWBs)
SEM Lab’s engineers have experience performing failure analysis of PWBs beginning in 1988. We have performed hundreds of individual failure analyses on PWBs and have accumulated a significant database of the variety of failure modes and mechanisms involved in PWB failures.
SEM images of failures in printed wiring boards (PWBs) and defects in the PWB surface finish are shown below.
