Automatic PCB NG Reject Conveyor

  Automatic PCB NG Reject Conveyor: Smarter Quality Sorting for SMT Production Lines   Turn Inspection Results into Reliable Material Flow In modern SMT manufacturing, SPI and AOI inspection systems can identify solder defects, component placement errors, and other quality risks. However, inspection alone does not prevent a defective PCB from moving into the next process. The real production challenge is what happens immediately after an NG or OK signal is generated: operators may need to intervene manually, good boards can be delayed, and defective boards may be mixed with qualified products. The Automatic PCB NG Reject Conveyor from Dongguan YongJi Electronic Technology Co., Ltd. is designed to close this gap. Installed after SPI, AOI, or other inspection equipment, it receives the NG/OK signal and automatically separates the boards. NG PCBs are lifted and stored in a reject buffer, while OK PCBs continue to the next process without unnecessary interruption. This creates a controll…
