PCB Edge Removal and De-paneling Methods: A Complete Overview
When making printed circuit boards (PCBs), individual boards are first combined into a big panel board. After components mounting or soldering, they are separated into individual boards using de-paneling tools. This article summarizes the three most common PCB de-paneling methods … Continue reading
