New energy vehicles impose strict requirements on PCBs: automotive radar boards withstand -40℃ to 125℃ temperature variations, while BMS boards require 10GHz+ high-frequency performance. Xiaopeng G9 uses embedded capacitor PCBs with Dk=2.2±0.05 to effectively suppress EMI4. The automotive electronics PCB market is projected to reach $30 billion by 2025, with ADAS boards accounting for over 40%
