Rigid flex printed circuit boards is a circuit board with FPC characteristics and PCB characteristics by combining the flexible circuit board and the rigid flex printed circuit boards after pressing and other processes according to the relevant process requirements in the process of the PCB board making. So, what are the application areas of the rigid flex printed circuit boards?
1. Industrial use: including industrial, military, and medical fields. Products in these fields have requirements for soft and hard boards: high reliability, high precision, low impedance loss, complete signal transmission quality, durability, etc. Because the manufacturing process is complex, the output is small and the production cost is high.
2. Mobile phone: The application of the rigid flex circuit boards in the mobile phone, the common turning point of the folding mobile phone, the image module, the button, and the radio frequency module, etc.
3. Consumer electronic products: The rigid flex printed circuit boards used in DSC and DV are the most representative. In terms of performance, the rigid flex printed circuit boards can connect different PCB boards in three dimensions to make components. Under the same line density, it can increase the total use area of the PCB, increase its circuit load, and reduce the signal transmission limit of the contact and the assembly error rate. In terms of structure, the rigid flex printed circuit boards are lighter and thinner, which can bend the wiring, which is of substantial help in reducing the volume and weight.
4. Cars: commonly used buttons on the steering wheel are 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, the reversing radar imaging system, the sensor, the car communication system, satellite navigation, rear-seat control panel and front-end controller connection board, exterior detection system, etc.
