PWB – Cross Sectioning – Buehler

This video from Buehler shows microsectioning process used to evaluate PWB quality by exposing a cross-sectional view of the microstructure at a selected plane. Microsectioning has become a standard requirement of PWB quality assurance due to the potential for hidden, subsurface defects, and for process control. The printed circuit board industry routinely cross sections copper plated through holes and surface via this process.
