Application knowledge of combining soft and hard PCB boards
The information comes from:the Internet posted on:2023-04-19
The birth and development of FPC and PCB have given birth to new products of soft and hard composite boards. Therefore, the combination of soft and hard circuit boards is a circuit board that combines flexible circuit boards and hard circuit boards according to relevant process requirements through pressing and other processes, and has FPC and PCB characteristics. Today, the editor has organized an introduction to the application of soft and hard combination boards for everyone. Let's take a look together!
1. Industrial use - Industrial use includes soft and hard adhesive boards for industrial, military, and medical purposes. Most industrial parts require precision, safety, and non vulnerability. Therefore, the required characteristics of soft and hard boards are high reliability, high accuracy, low impedance loss, complete signal transmission quality, and durability. However, due to the high complexity of the process, the output is small, and the unit price is quite high.
2. Mobile phones - In the application of mobile phone software and hardware boards, common ones include foldable phone turning points, camera modules, keyboards, RF modules, etc.
3. consumer electronics - Among consumer products, DSC and DV represent 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. Therefore, under the same line density, the total usable area of the PCB can be increased, which relatively improves its circuit carrying capacity, reduces the signal transmission limit and assembly error rate of the contacts. On the other hand, due to the lightweight nature of soft and hard boards, they can be bent for wiring, which greatly helps to reduce volume and weight.
4. Automobile - In the use of automobile hardware and software boards, it is usually used to connect the keys on the steering wheel to the mainboard, the connection between the vehicle video system screen and the control panel, the operation connection of the audio or function keys on the side door, the sensor of the reversing radar image system (including air quality, temperature and humidity, special gas regulation, etc.), the vehicle communication system, satellite navigation, rear seat control panel and the front controller connection board Vehicle external detection system, etc.
