Rigid-flex circuits are a hybrid construction flex circuit consisting of rigid and flexible substrates which are laminated together into a single structure. Rigid-flex PCBs provide a simple means to integrate multiple PCB assemblies and other components including display, input or storage devices with thin, light composites that integrate wiring in thin, flexible ribbons between sections. One of the great advantages of Rigid Flex is the possibility of designing the circuit that will have to be adapted to the device and not the other way round, therefore the construction of a device according to the circuit, in fact they can replace wiring and complicated assembly components providing significant savings without a reduction in performance.
