S-L680B Inline AOI Machine by Southern Machinery
Inline AOI catches placement and soldering defects while boards are still in the line.
What is this machine used for?
The S-L680B is an inline AOI that inspects PCBs as they pass through the conveyor, detecting missing or misaligned components, soldering defects, and surface faults in 2D and 3D.
- SMT and THT lines with components down to 0201
- Post-placement and post-soldering quality gates
- High-mix EMS, automotive, and medical PCBA
- Online OK/NG signaling to downstream equipment

How it fits into a complete PCB assembly line
- After pick-and-place or insertion, before reflow/wave soldering
- After soldering, as a final appearance and joint quality gate
- OK boards flow forward; NG signal to reject/buffer module
- Connects with SMEMA-compatible conveyors, loaders, and unloaders
Key selection parameters for buyers
- PCB sizes and thicknesses to be inspected
- Smallest component size (0201; 01005 upgrade path)
- Online vs offline programming; repair station
ROI perspective
The S-L680B replaces visual inspection and stops defects before soldering, cutting rework. Southern Machinery provides ROI modeling case-by-case; payback comes from labor and rework savings.
