FAQ About Rigid-Flex PCB
Short answers for product selection, supplier qualification and system-cost decisions.
What Is a Rigid-Flex PCB?
A rigid-flex PCB integrates rigid component-support areas and flexible circuit areas into one laminated printed circuit structure. The flex zones fold or route between rigid sections, eliminating separate cables and board-to-board connectors. Its fabrication data must define the rigid stack, flex stack, transition zones, bend requirement, coverlay and stiffeners.
Rigid-Flex PCB vs Rigid PCB vs Flex PCB
A rigid PCB supports components on a flat board. A flex PCB provides a bendable interconnect. Rigid-flex integrates both functions into one laminated structure. Choose rigid-flex when component support and controlled folding must coexist without separate connectors.
When Should You Use Rigid-Flex PCB Instead of Separate Rigid and Flex Boards?
Use rigid-flex when connector reduction, enclosure space, lower assembly count, controlled folding or interconnect repeatability has measurable system value. Keep separate rigid and flex boards when modular replacement, independent sourcing or a simple low-volume cable interface is the stronger requirement. The final selection should compare complete assembly cost, mechanical risk and service strategy—not bare-board price alone.
