FPC meets the characteristics of miniaturization and high density of internal parts of new energy vehicles. The texture of traditional PCB rigid board is relatively hard. Under the trend of miniaturization and high density of new energy automotive electronic components, traditional Rigid PCB is gradually unable to meet the quantity and quality requirements of new automotive electronic components.
Compared with the traditional copper wire harness solution, FPC is highly integrated, ultra-thin, and easy to automate production. It has outstanding advantages in terms of safety, light weight, and regular layout. Its usage in new energy vehicles has increased significantly, and it has become a three-dimensional line structure important material.
The application of FPC in the vehicle field covers car lights, display modules, BMS/VCU/MCU three power control systems, sensors, advanced auxiliary systems and other related scenarios.
FPC helps new energy automobile factories reduce costs and increase efficiency.
FPC is conducive to reducing the weight of automotive electronic components. At present, automotive wiring harnesses account for 2% of the total weight of the vehicle, and the application of FPC makes it more feasible to reduce the weight of new energy vehicles. If a car uses FPC flat wire harness instead of traditional wire harness, the overall weight of the wire harness will be reduced by about 50%, and the volume will be reduced by about 60%. Moreover, the integration of electronic modules, switches and FPC harnesses can reduce the use of connectors and accessories and reduce costs.
According to ifixit data, it is expected that the number of FPCs for new energy vehicles will exceed 100 pieces, of which the number of FPCs for battery voltage monitoring can be as high as 70 pieces.
Ningde Times and BYD, the first echelon of domestic power batteries, have already applied FPC in batches in the pack link.
It is estimated that the global automotive FPC market will reach 7 billion yuan in 2022.
According to the forecast of PCB Information, the market size of flexible circuit boards (FPC) for automobiles in 2018 will reach 5.3 billion yuan, a year-on-year increase of 8.4%.
It is estimated that from 2016 to 2022, the annual growth rate of automotive FPC will remain between 6% and 9% for a long time, and the market size of automotive FPC will increase to 7 billion yuan in 2022.
