Flex-Rigid

Flex-rigid is a type of circuit board design that combines flexible and rigid sections within the same substrate. The flexible portions allow the board to bend and conform to curved surfaces, while the rigid areas provide structural support and stability for components. This hybrid approach enables the circuit board to maintain its functionality while also being able to flex and adapt to different form factors and product designs. Flex-rigid boards are commonly used in applications where space is limited and the ability to bend or wrap around structures is required, such as in portable electronics, wearables, and automotive electronics. The construction typically involves layering flexible and rigid materials, often using a combination of polyimide films, copper traces, and rigid laminates. By blending flexibility and rigidity, flex-rigid circuit boards offer enhanced design flexibility and reliability compared to traditional rigid-only or flexible-only PCBs.
