Pure flex PCBs are ideal for simple interconnects, dynamic flexing, and space-constrained designs without complex circuitry. Rigid-flex combines the benefits of both worlds: flexible sections for bending and rigid sections for component mounting. Choose rigid-flex when you need to eliminate connectors between boards or require complex circuits in a folding form factor.
Best Choice
Application Dependent
Rigid-flex excels when you need to combine circuit complexity with mechanical flexibility. It's often the best choice when the alternative is multiple PCBs connected with cables or connectors.
Pure flex PCBs are the right choice for simpler applications, especially when maximum flexibility or lowest board cost is the priority.
While rigid-flex boards cost more than pure flex, total system cost often favors rigid-flex by eliminating connectors, cables, and assembly steps.
Both technologies are highly reliable when properly designed. Rigid-flex eliminates connector failure points, while pure flex avoids the complex transitions between rigid and flex sections.
We manufacture both flex and rigid-flex, so recommendations are based purely on your needs.
We help calculate total system cost to determine which technology offers best value.
Our engineers can often simplify rigid-flex designs to reduce cost while maintaining performance.
Rigid-flex capabilities up to 20 layers for the most complex applications.
Critical rigid-to-flex transition zones designed for maximum reliability.
Consistent quality from early prototypes through high-volume manufacturing.
Yes, but it requires redesign. The good news is that rigid-flex often simplifies the overall system design by eliminating connectors. Our engineers can help evaluate the conversion.
Not always at the system level. While the bare board costs more, connector elimination, reduced assembly labor, and improved reliability often result in lower total cost, especially at volume.
The flex sections in rigid-flex can match pure flex flexibility. However, bend areas should be designed with 1-2 layers for optimal flex performance.
We have no minimum order quantity. We produce rigid-flex prototypes in quantities as low as 1-5 pieces.
Rigid-flex typically adds 3-5 days to lead time due to additional processing steps. Quick-turn rigid-flex prototypes are available in 7-10 days.
