FAQ

Answers to the most common questions about rigid-flex PCBs

1. What are rigid-flex PCBs and what are they used for?

Rigid-flex PCBs combine rigid and flexible circuit areas. They provide mechanical stability in the rigid sections and flexibility in the flex zones, enabling compact, lightweight, and robust designs—ideal for medical devices, aerospace, automotive electronics, and portable equipment.

2. What advantages do rigid-flex PCBs offer compared to purely rigid or purely flexible PCBs?

Rigid-flex boards reduce the number of connectors and cables, save space, increase reliability, and lower assembly costs. They enable complex designs with high electrical integrity and excellent mechanical durability.

3. What materials and constructions are typical in rigid-flex PCBs?

Rigid sections typically use FR-4 or similar laminates, while polyimide is common in the flexible layers. Additional elements include coverlays, prepregs, copper foils, and stiffeners for added stability. The stack-up integrates both rigid and flexible layers into a single PCB.

4. How are rigid-flex PCBs manufactured?

The manufacturing process includes preparing rigid and flexible materials, lamination, circuit patterning (photolithography, etching), via drilling, copper plating, applying coverlays in flex areas, laminating rigid zones, integrating stiffeners if required, contouring, surface finishing, and comprehensive testing (optical, electrical, and mechanical).

5. What technical specifications and limitations must be considered?

Important factors include minimum bend radius, trace width and spacing, thickness of the flexible areas, transitions between rigid and flex layers, layer count, and material properties such as Tg and CTE. Limitations arise from higher manufacturing complexity, increased costs, and potential warpage under mechanical stress.

6. Which industries and applications benefit most from rigid-flex PCBs?

Rigid-flex PCBs are ideal for applications requiring high reliability, compact design, and resistance to motion or vibration—for example in medical technology, automotive, aerospace, wearables, military, and telecommunications. They can also replace systems that previously relied on multiple rigid boards and cable connections with a single integrated rigid-flex solution.
