The emergence of FPC and PCB has given rise to new flexible and rigid combination board products, which combines the characteristics of FPC and PCB, and is a kind of circuit board that combines flexible circuit boards and rigid circuit boards through pressing and other processes. Today, I will introduce to you the application of rigid-flexible combination board!

1. Industrial use: Rigid-flex boards are used in industrial, military and medical fields. Due to the high demands of industry for precision, safety and durability, rigid-flex PCBs need to have characteristics such as high reliability, high precision, low impedance loss, complete signal transmission quality and durability. However, the price is relatively high because of the complicated production process and small output.

2. Mobile phone: In mobile phone, the combination of hard and soft boards is widely used in folding mobile phone folding, camera module, keypad, RF module and other positions.

3. Consumer electronics: In consumer products, DSC and DV represent the development of soft and hard boards. They are mainly categorized into two directions: performance and structure. In terms of performance, soft and hard boards can three-dimensionally connect different PCB hard boards and components, increase the total area of use of the PCB, improve circuit-carrying capacity, and reduce the signal transmission limit of the contacts and the assembly error rate. At the same time, because the soft and hard boards are thin and light and can be bent wiring, it is very helpful to reduce the volume and weight.

4. Automobiles: In automobiles, rigid-flex boards are used to connect the buttons on the steering wheel to the main board, the connection between the vehicle video system screen and the control panel, the operation connection of audio or function keys on the side doors, the sensors of the reversing radar image system (including air quality, temperature and humidity, and special gas conditioning, etc.), the vehicle communication system, the satellite navigation, the rear-seat control panel and the front-end controller connecting boards, vehicle external detection system, and other places.
