Product Introduction – Dual Track NGOK Collector (Model XY-NG250S)
Also known as: PCB NGOK Loader / NG-OK Reject Conveyor (Dual-lane)
The XY-NG250S is a high-efficiency dual-track NG/OK PCB collector, designed to automatically sort and collect NG (No Good) and OK (Good) PCBs after AOI, ICT, or functional testing stages in an SMT production line.
It features two independent tracks, allowing separate handling of NG and OK boards or supporting dual-lane inspection lines, increasing throughput and quality control.
Key Features:
Dual-lane structure: Simultaneous handling of two separate PCB lanes
Automatic NG/OK separation: Based on signal from AOI/tester
Flexible configuration: Can be set as OK unloader, NG collector, or both
Smooth and gentle PCB handling: Prevents board damage
HMI control or button panel: User-friendly interface
SMEMA interface compatible: For inline integration with test equipment
ESD-safe design: Suitable for sensitive electronic boards
Alarm system: Alerts when collection tray is full or misaligned

FAQ Guide – Dual Track NGOK Collector (Model XY-NG250S)
1. What is the function of the XY-NG250S?
The XY-NG250S is a dual-lane NG/OK sorting and collection machine used after inspection or test equipment such as AOI, ICT, or functional testers. It automatically separates and collects NG (No Good) and OK (Good) PCBs based on control signals.
2. How does the NG/OK logic work?
The NGOK Collector receives a signal from upstream inspection equipment (e.g., AOI). Depending on the signal:
OK boards are transferred to the OK collection tray
NG boards are diverted to the NG collection tray
The sorting is fully automatic and based on preprogrammed logic in the PLC
3. What makes it “dual track”?
It has two independent conveyor lanes, allowing:
Simultaneous operation of two separate PCB lines
NG/OK sorting in each lane
Increased throughput and better space utilization
4. Is it compatible with SMEMA?
Yes. The XY-NG250S is equipped with dual-lane SMEMA interfaces, enabling easy communication and synchronization with upstream and downstream equipment.
5. What PCB sizes are supported?
Standard support for PCB sizes: 50 × 50 mm to 250 × 330 mm per track
Larger or smaller sizes can be customized
6. What control interface does it use?
Available in touchscreen HMI or button panel versions
PLC-controlled for reliable sorting logic and user-friendly operation
Some models include status indicators, alarms, and manual override functions
7. Does it require air pressure?
Only if equipped with pneumatic stoppers or pushers
In such cases, air pressure of 4–6 kg/cm² is required
Otherwise, the system operates electrically
8. What happens when the NG or OK tray is full?
The system will trigger an alarm via the signal tower light and optionally pause board intake
Operators will be prompted to replace the full tray before continuing
9. What optional features are available?
Signal tower light (3-color with buzzer)
Reject marking station (manual/automatic sticker or ink dot)
Barcode scanner bracket for traceability
MES interface for integration with factory data systems
Safety light curtain for operator protection
10. What routine maintenance is needed?
Clean belts, sensors, and collection bins regularly
Lubricate mechanical rails and components monthly
Check sensors and signal wiring weekly
Replace worn belts and damaged trays as needed
11. What is the delivery lead time?
Standard model: 3–5 working days
Customized configurations: 7–10 working days
Spare parts and accessories are typically in stock
12. What industries use this equipment?
SMT factories (AOI/ICT output stations)
LED assembly lines
Automotive electronics
High-mix, high-throughput PCB lines
