Rigid-flex PCB is a new type of printed circuit board that combines the durability of a rigid PCB and the adaptability of a flexible PCB. In all types of PCBs, the combination of rigid and flexible is the resistance to harsh application environments. Therefore, it is favored by manufacturers of industrial control, medical, and military equipment, and mainland enterprises are gradually increasing the proportion of rigid-flex board in the overall output.
Industrial use-Industrial use includes rigid-flex board 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 soft and hard boards are: high reliability, high precision, low impedance loss, complete signal transmission quality, and durability. However, because of the high complexity of the manufacturing process, the output is small and the unit price is quite high.
2. Mobile phone-the application of soft and hard boards in mobile phones, such as folding mobile phone turning point (Hinge), image module (camera module), button (keypad) and radio frequency module (RF Module), etc. are common.
3. Consumer electronic products-among consumer products, DSC and DV are representative of the development of soft and hard boards, which can be discussed in terms of performance and structure. In terms of performance, rigid and flexible boards can connect different PCB rigid boards and components three-dimensionally, so under the same circuit density, the total use area of the PCB can be increased, the circuit load capacity can be increased, and the signal transmission limit of the contacts can be reduced. Assembly error rate. On the other hand, since the flexible and rigid board is lighter and thinner, it can bend the wiring, so it is helpful to reduce the volume and reduce the weight.
4. Automobile-the use of soft and hard boards in automobiles, commonly used are the buttons on the steering wheel connected to the motherboard, the connection of the car video system screen and the control panel, the operation 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 exterior detection systems, etc.
