Rigid-Flex PCBs: The Basics
Rigid-flex replaces connectors and cables with integrally formed bends, saving weight and failure points β at the cost of trickier design and higher unit price.
Where it pays off
Aerospace, medical and wearables gain most from removing connectors.
Bend rules
Control bend radius, stack-up at the bend and coverlay flexibility.
Design traps
Static vs dynamic flex, and copper in the bend, are the classic failure modes.
Key Takeaways
Key Takeaways
- Best where connectors are the weak link.
- Respect bend radius and coverlay rules.
- Keep copper out of dynamic bends.
