The rigid Flex PCB is a new type of PCB with both the durability of rigid pcb and the adaptability of flexible PCB. Among all types of PCB, the soft Flex PCB has the strongest resistance to harsh application environment. Therefore, it is favored by industrial control, medical and military equipment manufacturers. Enterprises in the mainland are gradually increasing the proportion of soft Flex PCB in the total output Proportion.
Rigid-Flex PCB
1.Industrial use - industrial use includes the combination of hardware and software for industrial, military and medical use. Most of the industrial parts need the characteristics of accuracy, safety and non vulnerability. Therefore, the characteristics required for the soft and hard board are: high reliability, high accuracy, low impedance loss, complete signal transmission quality and durability. But because of the complexity of the process, the output is small and the unit price is high.
2.Mobile phone - the application of software and hardware in the mobile phone, including hinge, camera module, keypad, RF module, etc.
3.In consumer electronic products - consumer products, DSC and DV are representative of the development of soft and hard boards, which can be divided into two main axes: performance and structure. In terms of performance, soft and hard boards can connect different PCB hard boards and components in three dimensions, so under the same circuit density, the total area of PCB can be increased, the circuit load can be increased relatively, and the signal transmission limit and assembly error rate of the contact can be reduced. On the other hand, because the soft and hard board is light and thin, it can flex the wiring, so it is helpful to reduce the volume and weight.
4.Automobile - the purpose of the soft and hard board in the automobile, commonly used are the key to connect the motherboard on the steering wheel, the connection between the screen of the vehicle video system and the control panel, the operation connection of the audio or function key on the side door, the reversing radar image system, the sensor (including air quality, temperature and humidity, special gas regulation, etc.), the vehicle communication system, satellite navigation, rear seat control panel and Front end controller connection board, external detection system and other purposes.
