About the introduction of Rigid-flex PCB

 1. Classification of Rigid-flex PCB

  It can be divided into two categories of products: rigid-flex composite PCB and rigid-flex PCB. Rigid-flex composite PCB is the PCB that combine Flex PCB and rigid PCB together in the manufacturing process. There are common blind hole and buried hole designs among them. Therefore, higher-density circuit design is possible. And the technology of the Ridgid-flex PCB is to make the flex PCB and the rigid PCB separately and then press them into a single circuit board with signal connection but no through-hole design. But at present, the commonly used “rigid-flex board” collectively refers to all rigid-flex board products without subdividing the two.

 2. The advantages of rigid-flex PCB

  The rigid-flex PCB is flexible, can be wired three-dimensionally, can change shape according to space constraints, is resistant to high and low temperature, flame resistance, can be folded without affecting the signal transmission function, can prevent electrostatic interference, stable chemical changes, stability, and reliability High, which is conducive to the design of related products, can reduce assembly man-hours and errors, and improve the service life of related products, so that the size of the application product is reduced, the weight is greatly reduced, the function is increased, and the cost is reduced.

 3. Application of rigid-flex PCB

  Industrial use-Industrial use includes rigid and flexible boards used in industry, military and medical. Mobile phone-the application of soft and hard boards in mobile phones, such as folding mobile phone turning point (Hinge), image module (Camera Module), button (Keypad) and radio frequency module (RF Module), etc. are common. Consumer electronic products-Among consumer products, DSC and DV are representative of the development of soft and hard boards. Automobile-In the use of soft and hard boards in automobiles, there are commonly used buttons on the steering wheel to connect to the motherboard, the connection of the car video system screen and the control panel, the operation connection of the audio or function keys on the side door, the reversing radar imaging system, and the sensor (Sensor, including air quality, temperature and humidity, special gas regulation, etc.), vehicle communication system, satellite navigation, rear seat control panel and front-end controller connection board, vehicle exterior detection system, etc.
