Next-generation automotive ADAS sensing modules, including 77–81 GHz radar, LiDAR, and mmWave sensor arrays, require PCBs with ultra-stable dielectric properties, low insertion loss, and phase-coherent RF routing. Performance depends on maintaining consistent Dk/Df, low-loss mmWave signal propagation, and minimal EMI, even under harsh thermal cycling, vibration, and humidity conditions in vehicles. High-frequency sensor PCB...
