The FPCB board is a new printed circuit board for the endurance and flexible FPC of a rigid PCB. According to Xiaobian, Soft Crave Plate is known, the soft and hard bond board is favored by medical and military equipment producers due to special advantages.  
 
1, classification of soft and hard bond board  
It can be distinguished into two major class products of the soft and hard composite plate and the soft bonding plate. The difference is the technique of the soft and hard composite panel, which can be combined in the process in the process, where there is a common blind hole and a buried hole design. Therefore, there can be a higher density circuit design, and the technology of the soft bonding plate is the soft plate and the hard plate, and then the synthesis of a single piece of circuit board is pressed, and the signal is connected but the design of the unconservatory. However, it is currently used to collect all soft and hard bond board products in the "soft and hard bonding plate" without fine.  
 
2, the advantages of the soft bonding board  
The soft and hard bonding plate has a flexible, a stereo wiring, and the spatial restriction change shape, high low temperature, flame-free, foldable without affecting signal transmission function, prevent electrostatic interference, chemical changes, stability, and trustidity High, facilitating the design of related products, can reduce assembly work and errors, and improve the service life of the product, so that the volume of application products is reduced, the weight is greatly reduced, and the function is increased, and the cost is reduced.  
 
3. Application of soft and hard combination board  
Industrial use - industrial uses contain hard and hard boards used in industrial, military and medical. Mobile phone - in the soft-hard board in the mobile phone, commonly used, the transfusion of the folded mobile phone, the video module (Camera Module), a keypad, and RF module, and the like. In consumer electronics-consumer products, DSC and DV development is representative. Cars - In the use of the soft and hardboard in the car, there is commonly used in the steering wheel, the buttons, the car video system screen and the connection of the control disc, the operation of the side door audio or function key, reversing radar imaging system, sensor (Sensor, air quality, temperature and humidity, special gas adjustment, etc.), vehicle communication system, satellite navigation, rear seat control disk and front-end controller connection plate, car external detection system, etc.
