Introduction
The SMT NG&OK Unloader YU-390 is a state-of-the-art PCB handling and sorting system designed to improve automation, efficiency, and quality control in modern SMT production lines. Specifically engineered for electronics manufacturers producing consumer electronics, automotive modules, LED boards, and communication devices, the YU-390 streamlines the process of separating good (OK) and defective (NG) boards immediately after inspection. This automated classification reduces manual labor, lowers error rates, and ensures consistent production standards.
The YU-390 incorporates a stable conveyor and precision guide system, providing smooth and reliable PCB transfer. Its ESD-safe construction safeguards sensitive components while its durable framework ensures long-term performance in high-speed production environments. The compact and modular design enables easy integration even in space-constrained SMT lines.
Flexible operational modes allow the YU-390 to handle different PCB sizes, inspection results, and production requirements. It connects seamlessly with AOI, SPI, and other inspection equipment via standard interfaces, supporting continuous production without bottlenecks. The intuitive control panel, clear status indicators, and easy-access maintenance points simplify daily operations and reduce downtime.
By automating NG and OK board separation, the YU-390 enhances workflow continuity, improves line efficiency, and maintains high product quality. Its versatility and reliability make it ideal for high-mix, high-volume SMT manufacturing environments where precision, speed, and operational flexibility are critical.
