PCB News - Market analysis of automotive PCB board industry

Printed circuit boards are the support of all electronic components, and the increase in the proportion of automotive electronics will undoubtedly drive the demand for automotive PCBs. In the application field of automotive PCBs, PCBs are mainly used in automotive functional systems such as electric control, assisted driving, and in-vehicle communication. With the development of new energy vehicles and the deepening of automotive electronics, the area required for automotive PCBs will gradually increase. Compared with traditional vehicles, new energy vehicles have higher requirements for the degree of electronization. The state's support for new energy vehicles will increase the demand for electric power control systems and become a new growth point for automotive electronics.

The proportions of single and double panels, 4-layer boards, 6-layer boards, and 8-16-layer boards in automotive PCBs are 26.93%, 25.70%, 17.37%, and 3.49%, respectively, accounting for about 73% in total; HDI, FPC, and IC The carrier boards accounted for 9.56%, 14.57%, and 2.38%, respectively, accounting for about 27% in total. It can be seen that PCB multilayer boards are still the main demand for automotive electronics. Automotive PCB demand is dominated by 2-6 layers. PCB accounts for about 2% of the entire electronic device cost. The average PCB consumption per traditional car is about 1 square meter, and the consumption of high-end models is 2-3 Square meters.

In new energy vehicles, corresponding BMS, VCU, and MCU have been newly added. Among them, BMS generally adopts multi-layer boards with better stability, and the unit value is higher than other PCB boards. The use area varies based on different design schemes. The average use area is about 3-5 square meters, so the PCB bicycle value of new energy vehicles is higher. On the other hand, as the penetration rate of ADAS increases, the shipment of millimeter-wave radars, the core component of ADAS, is expected to increase. High-frequency PCBs have become the main substrate of millimeter-wave radars due to their stable performance. They are more expensive than ordinary PCBs. The increase in the proportion of PCBs has led to an increase in the unit price of PCBs for the entire vehicle.

As sales of new energy vehicles are growing faster than pure fuel vehicles, their share of overall vehicle sales is expected to increase, driving the volume and price of the automotive PCB market to rise. In terms of categories, the annual output value of the PCB market for new energy vehicles from 2019 to 2021 is in the range of 10-17 billion yuan, fuel vehicles are in the range of 44-46 billion yuan, and the overall value is in the range of 56-63 billion yuan. With the gradual transition of traditional cars to autonomous driving through ADAS and the promotion of new energy vehicles, the penetration rate of automotive electronics continues to increase, and the use of automotive PCBs has become more and more widespread.
