In traditional automobiles, PCBs are mainly used in power control systems, body sensors, navigation systems, entertainment systems, etc., while the PCB increment of electric vehicles mainly comes from the vehicle controller VCU, microcontroller unit MCU, battery management system BMS. Due to its complex architecture, BMS requires a large number of PCBs, with a main control circuit area of approximately 0.24 square meters and a sub control unit area of 2-3 square meters. It generally uses multi-layer boards with better stability, resulting in greater individual value. In addition, in car entertainment, new energy vehicles, and millimeter wave radar will drive an increase in the proportion of HDI, thick copper plates, FPC, and high-frequency boards. In 2018, HDI board, thick copper board, RF board, and flexible/rigid flexible board accounted for 7.5%, 4.9%, 4.8%, and 12% respectively. In 2020, the proportion has increased to 11.5%, 6.5%, 7.0%, and 15% respectively, and the total proportion has rapidly increased from 29.2% to 40%. With the increasing volume of new energy vehicles, it is expected that the global automotive PCB market will exceed 100 billion yuan by 2023, and the CAGR is expected to exceed 25% from 2020 to 2025.
