Rigid Flex PCB Design for Manufacturing: The Hidden Rules That Prevent Costly Re-Spins
Rigid-flex PCB technology eliminates board-to-board connectors, reduces assembly steps, and improves reliability in compact enclosures—but only when the layout is created with fabrication and bending in mind. Unlike conventional rigid PCBs, a rigid-flex board combines FR-4 or polyimide rigid sections with flexible polyimide layers that bend, fold, or twist during installation and product use. The…
