Flex pcb's applications on automotive

As Huawei new energy vehicle main fpc part supplier, have rich experience in bare flex pcb, pcba, and final whole fpc product.

Flexible circuit board (FPC) is widely used in automobiles, mainly used in the following aspects:

‌1Automotive lighting system: With the development of automotive lighting system to LED direction, FPC because of its flexible characteristics can adapt to complex shapes and small Spaces, provide stable electrical connection, and withstand vibration and temperature changes.

‌2.Vehicle electronic equipment ‌ : FPC is widely used in vehicle display, instrument panel, sound system and other equipment, because of its lightweight, thin characteristics provide more design possibilities, to ensure the lightweight and high efficiency of electronic equipment.

3. Battery Management system (BMS): In electric vehicles, FPC is used in the battery management system, which can realize complex circuit wiring, reduce the wiring between battery modules, and improve the simplicity and safety of the system.

‌4.Automatic driving sensor connection ‌ : FPC can realize high-density sensor connection in a small space to ensure the accuracy and reliability of the automatic driving system ‌

‌5.Vehicle camera module: FPC is widely used in vehicle camera module. It has the characteristics of high integration and ultra-flexibility, which is suitable for high-density installation and improves system safety and stability.

‌

Advantages of FPC and its role in automotive electronic systems ‌ :

1. High density wiring and excellent bending ‌ : FPC has high density wiring and high bendability, which is suitable for the complex spatial layout of automobile interior.

2. Lightweight and process flexibility: The lightweight characteristics of FPC make it provide more design possibilities in the limited space of the car, while the process flexibility is high, suitable for automated production.

3. ‌ safety: In the battery management system, FPC can monitor the voltage and temperature of the battery cell to achieve data acquisition and transmission, and has the function of over current protection to protect the battery cell from abnormal short circuit.

‌Future development trend and cost-benefit analysis ‌ :

‌Alternative to traditional wiring harness system: In the future, new energy vehicles will largely use FPC to replace the traditional wiring harness system to solve the problem of space utilization and efficiency.

Highly integrated and automated production: FPC's highly integrated and automated assembly advantages make the production process more efficient and reduce labor costs.
