Advanced driver-assistance systems (ADAS) rely heavily on multi-sensor fusion, where radar, LiDAR, ultrasonic sensing, and camera modules continuously exchange high-frequency data. To maintain real-time performance and safety-critical reliability, the ADAS PCB must deliver low-loss signal transmission, stable dielectric behavior, and tight impedance control under prolonged automotive thermal and vibration stress. High-frequency ADAS RF chains—particularly 24...
