Millimeter-wave Radar is a key sensor in automotive ADAS systems, responsible for detecting the distance, speed, and direction of surrounding vehicles, pedestrians, and obstacles, providing data support for intelligent driving functions. Its performance is closely related to PCBA assembly quality. Our Millimeter-wave Radar PCBA processing focuses on high-precision soldering and strict quality control, ensuring the radar has high detection accuracy, long detection distance, and strong anti-interference ability. It is designed to withstand harsh automotive environments, including high temperature, vibration, and rain and snow. With 7 SMT high-speed placement lines and professional testing equipment, we provide high-reliability PCBA assembly for Millimeter-wave Radar, meeting the requirements of ADAS systems.
