According to Digitimes article, the average PCB value of each BEV vehicle is about 5-6 times that of traditional fuel vehicles, and the highest PCB value in the vehicle is the electronic control system, which accounts for about half of the PCB value used in the entire vehicle. 

As the level and penetration rate of autonomous driving continue to increase, the average number of electronic products such as lenses and radars per vehicle will also continue to increase. Currently, automotive PCBs are mainly 4-8 layer boards, while self driving systems mostly use HDI boards with higher unit prices, which are about three times the price of 4-8 layer boards. The HDI price used by LiDAR (LiDAR) equipped with L3 and above self driving systems can reach tens of dollars, and it is also the main source of future increase in automotive PCB output value. 

According to the person in the industry, the proportion of 4-8 layer boards mainly used in automotive PCBs in 2023 is about 40% of the overall automotive PCB, and it will decrease to 32% by 2026; The proportion of HDI boards with higher unit prices has increased from 15% to 20%; FPC board increased from 17% to 20%, thick copper board and RF board increased from 8% and 8.8% to 9.5% and 10.8% respectively, while single and double layer panels with lower unit prices decreased from 11.2% to 7.7%.
