Printed Circuit Board (PCB) Micro-Sectioning For Quality Control

Quality control in Printed Circuit Board (PCB) manufacturing is very important, including but not limited to drilling hole quality, Desmearing of drilled hole, plating thickness of various metals and integrating of the final production board. During the manufacture of printed circuit boards, test coupons are introduced in each production panel. This allows each panel to be tested without wasting actual production board. The coupon is separated from the panel to confirm product specifications have been met.
