FPCB board is a new type of printed circuit board with the durability of rigid PCB and the adaptability of flexible FPC. According to the editor of the soft and hard board manufacturer, the soft and hard board has been favored by medical and military equipment manufacturers due to its special advantages.
1. Classification of soft and hard board
It can be divided into two categories: flexible and rigid composite boards and flexible and rigid composite boards. The difference lies in the technology of flexible and rigid composite boards. Flexible and rigid boards can be combined in the manufacturing process. Among them, there are common blind and buried hole designs. Therefore, a higher-density circuit design is possible, and the technology of a flexible and rigid board is a design in which a flexible board and a hard board are separately manufactured and then pressed into a single circuit board, which has a signal connection but no through holes. However, the currently used "flexible and rigid combination boards" are collectively referred to as all flex and rigid combination products, without subdividing the two.
2, the advantages of soft and hard board
The flexible and rigid board has flexibility, can be three-dimensional wiring, change shape according to space constraints, high and low temperature resistance, flame resistance, can be folded without affecting signal transmission function, can prevent electrostatic interference, stable chemical changes, stability, reliability High, is conducive to the design of related products, can reduce assembly man-hours and errors, and increase the service life of related products, reducing the size of application products, significantly reducing weight, increasing functions, and reducing costs.
3. Application of soft and hard board
Industrial use-Industrial use includes hard and soft boards for industrial, military and medical use. Mobile phone-The application of soft and hard boards in mobile phones, common are folding phone Hinge, camera module, keypad and RF module. Consumer electronics-Among consumer products, DSC and DV are representative of the development of soft and hard boards. Automobiles-The use of soft and hard boards in automobiles is usually used to connect the motherboard''s buttons on the steering wheel, the connection of the car''s video system screen and the control panel, the operation connection of the audio or function keys on the side doors, the back-up radar imaging system, and sensors (Sensor, including air quality, temperature and humidity, special gas regulation, etc.), automotive communication systems, satellite navigation, rear seat control panel and front-end controller connection board, vehicle detection system, etc.
