Introduction to the application of soft and hard board

The hard copy circuit is a new type of printed circuit board that provides the durability of rigid printed circuits and the adaptability of flexible printed circuits.

Among all types of printed circuits, the combination of equipment and software is the most effective combination in a difficult application environment, and is therefore a priority for manufacturers of industrial, medical, and military equipment.

Domestic plants for PCBs and PCBs are also gradually increasing their total output. Quantity ratio.

1. Industrial use-Industrial uses include hard access boards for industrial, military and medical use.

Most industrial parts require precision, safety, and soil changes.

Therefore, the characteristics of hard and soft boards are as follows:

High reliability, high precision, low impedance, complete signal transmission quality and durability.

However, due to the complexity of this process, the result is low and the price is high.

2. When using a portable phone system, a portable phone can be used, which usually has a hinge, a camera module, a keyboard, and an RF module for a foldable mobile phone.

3. Among high-quality electronic products, DSS and DV represent the development of hard and soft boards, which can be divided into two main axes: performance and structure.

In terms of performance, rigid and flexible cards can be three-dimensionally connected with different playing cards and hard disk components of printed circuit boards. Therefore, under the same linear density, the total area of the printed circuit board can be increased, and the circuit load can be increased.

The locomotive and signal transmission restrictions can reduce the assembly error rate of the contact. On the other hand, because hard and soft plates are lighter and thinner, they can reduce cables, thereby greatly reducing their number and weight.

4. Vehicles: Use flexible and soft boards in automobiles.

Connect the mother card to the steering wheel, the connection between the vehicle's video system screen and the control panel, and the sound or function operation connection.

Side door keys, back radar system, sensors (air quality, temperature and humidity, special gas, etc.), vehicle communication system, satellite navigation, rear seat control panel, etc., etc., etc.
