What Is Omron AOI?
Omron AOI refers to a suite of inspection technologies designed to detect defects in printed circuit boards (PCBs) during surface mount technology (SMT) assembly.
These systems play a critical role in:
Catching solder joint defects, misalignments, missing components, and polarity errors
Reducing false calls and unnecessary rework
Supporting zero-defect manufacturing across demanding industries like automotive, aerospace, and telecom
Omron AOI fits into multiple stages of the SMT process:
Post-Placement Inspection: Verifies correct component type, orientation, and position.
Post-Reflow Inspection: Detects solder joint issues after reflow.
The VT-S730 is Omron’s flagship 3D AOI system, built for manufacturers who prioritize speed, accuracy, and smart integration.
Core Specs:
Camera: 4Mpixel (optionally 12Mpixel) top-view with telecentric lens
Oblique Cameras: 4 side-angle cameras for hidden solder joints
Projectors: 3D programmable DLP for height measurements up to 25mm
PCB Support: Up to 510 × 460 mm, 0.4 to 4 mm thick
Resolution: 15 μm/pixel
Weight: ~800 kg
Dimensions: 1100(W) x 1470(D) x 1500(H) mm
The system inspects everything from component offset and polarity to solder balls, bridges, lead presence, and OCR/2D codes.
Advanced 3D Inspection Capabilities
Unlike older 2D systems, Omron AOI uses depth data and multi-angle imaging to produce detailed inspections.
Omron’s Hybrid 3D Imaging:
Multi-Direction Moiré (MDM): Captures height and shape using phase shift technology.
Color Highlight™: Reconstructs 3D shapes using multicolor lighting, reducing reflections and improving contrast.
Full 3D Solder Joint Inspection (3D-SJI): Quantitative measurements of fillet height, length, wetting angle, volume, and more.
What It Catches Reliably:
Lifted or tilted components
Tombstoning
Cold solder joints
Foreign objects
Lead offset and posture
Solder bridges and balls
With five cameras and structured illumination, the VT-S730 sees what many others miss, including defects beneath and around densely packed components.
AI-Driven Accuracy & Optimization
AI is more than a buzzword here.
The VT-S730 uses self-optimizing algorithms to fine-tune inspection parameters based on production data.
Highlights:
AI Self-Optimization: Automatically adjusts defect thresholds and inspection logic.
Real-Time Feedback: Live 3D views allow simultaneous editing of inspection zones while production continues.
Process Histograms: Statistical insight into false calls and defect trends.
Defect Image Library: Helps refine tuning by referencing real inspection history.
These tools reduce operator guesswork, accelerate tuning, and support long-term inspection stability.
Programming Basics for Omron AOI
Programming the VT-S730 is designed to be fast and flexible – ideal for high-mix or rapidly changing lines.
Here is the step-by-step workflow:
1. Create a New Program
Define PCB size by marking two diagonal corners
Set fiducials for alignment, side recognition, and deformation checks
2. Register Components & Areas
Manual entry or import via CAD
Use e-iT (easy-image Teaching) tools for component auto-detection
3. Set Inspection Criteria
Define solder joint specs, offsets, and component tolerances
Configure oblique-angle cameras for hidden joints
4. Debugging
Run test inspections
Adjust based on real-time 3D feedback and histogram data
5. Offline Review
Use Omron’s review stations to finalize tuning without stopping the line
Time To Deploy:
Calibration: ~5 minutes using an automated calibration plate
Initial Program Setup: A few hours to a day, depending on board complexity
