RIGID-FLEX

Rigid-flex is a multilayer printed circuit board with both rigid and flex electric interconnecting layers. A composition of flexible and rigid substrates in a single circuit board creates unique opportunities. The technology allows designers to replace multiple PCBs interconnected with connectors, wires and ribbon cables to create a single circuit board while improving performance and reliability. Furthermore, because rigid-flex PCBs can be bent, folded or twisted, they make an ideal solution for optimizing applications with tight space limitations by using the third dimension.

DYCONEX has more than two decades of experience in the manufacture of rigid-flex technology. The resulting expertise has built up our solid reputation for excellence, especially where highly complex solutions are needed. Whether a 14-layer bookbinder PCB for the Herschel satellite, a high-density board for an F-1 steering wheel or a 3D miniaturization project in the field of medical implants, our expertise at DYCONEX in rigid-flex circuitry will serve you with a tailor-made, high-quality solution.
