The birth and development of FPC and PCB have spawned new products of soft and hard composite boards. Therefore, the soft and hard combined board is a circuit board with FPC characteristics and PCB characteristics, which is composed of the flexible circuit board and the hard circuit board by pressing and other processes according to the relevant process requirements.
The application of soft and hard board
1.Industrial use
Industrial uses include soft and hard adhesive boards for industrial, military and medical applications. Most industrial parts require precision, safety and no vulnerability. Therefore, the required characteristics of soft and hard boards are: high reliability, high precision, low impedance loss, complete signal transmission quality and durability. However, due to the high complexity of the process, the yield is small and the unit price is quite high.
2.Cell Phone
In the application of mobile phone hardware and software board, the common ones are folding mobile phone round point, camera module, keyboard, RF module and so on.
3.Consumer electronics
In consumer products, DSC and DV are representative of the development of soft and hard plates, which can be divided into two main axes: performance and structure. In terms of performance, soft boards and hard boards can be connected to different PCB hard boards and components in three dimensions. Therefore, under the same linear density, the total use area of the PCB can be increased, the circuit carrying capacity can be relatively improved, and the signal transmission limit of the contact and the assembly error rate can be reduced. On the other hand, because the soft and hard board is thin and light, it can bend the wiring, so it is of great help to reduce the volume and weight.
4.Cars
In the use of automotive soft and hard boards, it is usually used to connect the keys on the steering wheel to the motherboard, 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, Reversing radar image system sensors (including air quality, temperature and humidity, special gas regulation, etc.), vehicle communication systems, satellite navigation, rear seat control panel and front controller connectors, vehicle external detection systems, etc.
