The application of flexible circuit board in the automotive industry :
Flexible circuit board ( FPC ) is increasingly used in the automotive industry, especially in the field of new energy vehicles.
FPC, which is a flexible circuit board, is a key component for signal transmission in electronic products. It uses flexible copper clad laminate as the substrate, with high assembly density, good bending, lightweight and highly automated process flexibility. With the advancement of automotive electronics and intelligence, the advantages of FPC have become increasingly prominent. Its bending, lightweight and highly automated features make it more and more widely used in the automotive field, including headlights, display modules, and power control systems. Especially in the new energy vehicle market, the demand for FPC has surged, becoming an important part of the BMS system of new energy vehicles. It is responsible for monitoring the voltage and temperature of power battery cells, ensuring accurate data transmission, and providing overcurrent protection. Compared with the traditional copper wire harness scheme, FPC shows significant advantages in safety, lightweight and layout regularity due to its high integration and ultra-thin thickness. In addition, FPC has a high degree of automation and is very suitable for large-scale mass production, so the trend of replacing copper wire harnesses has become increasingly apparent.
The application of FPC circuit board in automobile lamp can realize the functions of light control, signal transmission and integrated sensor, and improve the flexibility and intelligence. The flexibility, high space utilization, strong reliability, strong anti-interference ability and high temperature resistance of the FPC circuit board ensure stable operation. In smart car lights, FPC circuit boards bring more possibilities for lighting design, improve functionality and performance, and make car lights more intelligent and personalized.
The integration and innovation of FPC and CCS ( integrated busbar ) further improves the safety and reliability of the battery pack, simplifies the production process and reduces the cost. This integrated design not only improves the reliability of electrical connections, but also further optimizes the signal detection structure. With the continuous progress of technology and the continuous growth of market demand, the application prospect of FPC in the field of new energy vehicles is very broad.
