Rigid-flex PCBs are used in compact electronic devices such as cameras, wearables, aerospace modules, and medical probes where space and reliability are critical. The flexible sections allow the board to fold into three-dimensional shapes, reducing the need for connectors and cables.
Rigid-flex PCBs combine rigid and flexible layers in a single board, providing mechanical support for components while allowing the board to bend. Standard flexible PCBs are entirely flexible and often require stiffeners for component mounting. Rigid-flex eliminates connectors between sub-boards, improving reliability.
IPC-6013 covers qualification of flexible and rigid-flex boards, and IPC-2223 provides design guidelines. UL 94V-0 is a flammability rating. These standards are references for procurement and verification, but they do not guarantee that a specific product is compliant. Always confirm with the manufacturer.
Key parameters include board thickness, minimum trace width/spacing, minimum bend radius, flex layer count, total layer count, operating temperature, dielectric withstanding voltage, insulation resistance, impedance tolerance, copper weight, surface finish, flex cycle life, and maximum board size. These values must be verified for the specific application.
