How to Design FPC-to-PCB Connections for Better Assembly (DFx)

post on March 26, 2026

As electronic devices keep getting thinner and more compact, FPCs (flexible printed circuits) are used more and more. In some designs, FPCs even replace traditional PCBs. But no matter how advanced FPC technology becomes, it still needs to connect to … Continue reading →

The Difference Between ED Copper and RA Copper in FPC

post on March 12, 2026

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

post on March 10, 2026

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)?

post on March 4, 2026

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 →
