The advantages of rigid-flex PCB board

1). It can effectively save the space on the circuit board and eliminate the use of connectors

Because the FPCB and rigid pcb board has been combined, the space that originally needed to use the connector can be saved. For some circuit boards with high-density requirements, less connectors will be better. In this way, it also saves the cost of parts using the connectors. In addition, the space between the two boards can be made tighter by eliminating the need for connectors.

2). The signal transmission distance is shortened and the speed is increased, which can effectively improve the reliability

The traditional signal transmission through the connector is “circuit board→connector→flexible pcb board→connector→circuit board”, while the signal transmission of the rigid-flex PCB board is reduced to “rigid circuit board→flexible pcb board→rigid circuit board”, signal transmission distance between different media is shortened, and the problem of signal transmission attenuation between different media is also reduced. Generally, the circuit on the PCB board is made of copper, while the contact terminal of the connector is gold-plated, and the solder pin is fully tin-plated. Moreover, solder paste is required to be soldered on the circuit board, and the signal transmission between different media will inevitably be attenuated. If you switch to a rigid-flex PCB board, these media will become less, and the signal transmission ability can be relatively improved. For some products that require higher signal accuracy, it helps to improve their reliability.

3). Simplify product assembly and save assembly time

The use of a rigid-flex PCB board can reduce the man-hours for SMT parts, because the number of connectors is reduced. It also reduces the man-hours for assembly of the whole equipment, because it eliminates the assembly action of inserting the FPC board into the connector. It also reduces the cost of parts management and inventory, because the required parts is reduced, so the management cost becomes less.
