4 Main Applications Of Rigid-Flex PCB

1.Industrial application 

strial application includes rigid-flex PCB used in industry, military, and medical. Most industrial parts require the characteristics of accuracy, safety, and resistance to soil damage. Therefore, the characteristics required for rigid-flex PCB are high reliability, high precision, low impedance loss, complete signal transmission quality, and durability. However, due to the high complexity of the manufacturing process, the output is small and the unit price is relatively high.

2.Mobile phones

The application of rigid-flex PCB in mobile phones, such as folding mobile phone hinges, camera modules, keypads, and radio frequency modules, are common.

3.Consumer electronic products

Among consumer products, DSC and DV are representative of the development of rigid-flex PCB, which can be discussed in terms of performance and structure. Rigid and flexible boards can connect different PCB rigid boards and components three-dimensionally. Under the same circuit density, the PCB total usable area and the circuit carrying capacity can be increased. The signal transmission limit of the contacts can be reduced, and reduced Assembly error rate. On the other hand, because the rigid-flex board is lighter and thinner, the wiring can be bent easier, so reducing the volume and weight will be helpful.


Rigid-flex PCB is commonly used in the automotive industry. Here is a list of examples: the buttons on the steering wheel which connects to the motherboard, the connection of the car video system screen and the control panel, the operative connection of the audio or function keys on the side door, and the reversing radar imaging system, sensors (including air quality, temperature, and humidity, special gas regulation, etc.), vehicle communication systems, satellite navigation, rear-seat control panels, and front-end controller connection boards, vehicle detection systems, etc.

Rigid-flex PCB reduces the assembly size and weight of electronic products, avoiding wiring errors and increasing assembly flexibility. It also improves reliability and realizes three-dimensional assembly under different assembly conditions.Flexible Printed Circuits (FPC) flexible structure, small size, light weight, and flexibility can meet the needs of 3D assembly. Interconnection technology has been widely used and valued in the electronic communication industry. In recent years, the trend towards rigid-flex boards further shrinks the entire system, the volume, and enhance its function.
