PCB OK NG PCB Buffer Conveyor

The post-inspection bottleneck needs a smarter buffering solution On an SMT production line, AOI or SPI inspection is only one part of the process. The real challenge often begins after the inspection result is generated. OK boards must move quickly to the next process, while NG boards must be separated, stored safely, and held for manual review. Manual handling, temporary stacking, or basic conveyors can lead to mixed boards, incorrect routing, unnecessary waiting, and even a line stoppage caused by a single abnormal PCB. The YongJi PCB OK NG PCB Buffer Conveyor is designed for exactly this situation. After receiving the NG or OK signal from AOI, SPI, or another inspection machine, it automatically routes each PCB. OK boards are transferred to the next process, while NG boards move to the upper conveyor path and are stored for operator review. More than a simple PCB Buffer, it functions as an intelligent material-handling point between inspection, judgment, review, and downstream man…
