The Difference Between ED Copper and RA Copper in FPC
Modern electronic devices keep getting smaller, and that trend has driven the widespread use of Flexible Printed Circuit Boards (FPCs). One interesting thing about FPCs is that in many designs you can actually see the internal traces from the outside, … Continue reading

FPC Structures — Single-Sided and Double Access Designs
FPCs (Flexible Printed Circuit Boards) can be categorized by their structure and complexity. Common types include single-layer, double-layer, and multi-layer flexible circuits. There is also a hybrid design called rigid-flex, which combines both flexible and rigid PCBs in the same … Continue reading

What Is an FPC (Flexible Printed Circuit Board)?
Caption: The FPC is inserted into a connector on the PCB. At a basic level, FPCs and PCBs are very similar in both function and structure. Whether it’s an FPC or a PCB, both use copper traces on the surface—and … Continue reading

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

PCB Edge Removal and De-paneling: Stamp Hole Design
In most PCB (Printed Circuit Board) designs, panels are usually connected using V-cuts or tabs/ribs, and then separated with a V-cut scoring machine or a router de-panel machine. However, besides these two common connection methods, there’s another approach called the … Continue reading
