Machine Introduction
The Underfill Adhesive Automated Optical Inspection System AOI series (VF5100 single-side, VF5300 double-side) is designed for high-precision inspection of underfill adhesive climbing height, coverage, and defects around component edges. With advanced multi-angle imaging, UV/RGBW lighting, and a dedicated side-view optical system, the machine delivers accurate detection of UF adhesive, UV adhesive, RTV adhesive, and heat-dissipation materials. It supports inline inspection in dispensing and coating production lines, ensuring process stability and improving product reliability.
Key Features
- Five-sided inspection to capture adhesive conditions around all component edges.
- High-precision measurement of underfill adhesive climbing height and climbing percentage.
- Auto-generated contour lines for clear adhesive boundary visualization.
- UV, RGBW, and coaxial lighting for multi-material compatibility including UF, UV, RTV, and thermal adhesives.
- Real-image AI bubble inspection trained by production data for accurate bubble detection.
- Inline inspection capability for integration with dispensing and coating equipment.
- Save and review 5-side images for SPC analysis, traceability, and MES connection.
- Centralized control and remote management to improve production efficiency and reduce downtime.
- Closed-loop feedback enabling communication with dispensing/coating machines to optimize adhesive processes.
Production Line Solution
Our advanced side-view inspection system uses the innovative Sham optical principle to deliver clearer, wider imaging when capturing tilted PCB surfaces. By expanding the effective depth of field, the Sham lens ensures sharper edge details and more accurate defect detection compared with standard cameras. This enhanced optical design improves side inspection performance, boosts reliability, and supports high-precision SMT quality control.
The inspection system features UV light, RGBW light, and coaxial light options, allowing flexible illumination selection based on different adhesive materials. With optimized lighting combinations, the machine enhances contrast, improves defect visibility, and ensures accurate and consistent inspection results for SMT applications.
Examples Inspection
The system supports five-sided inspection, enabling comprehensive coverage of component sides that a standard front camera cannot physically capture. By combining multiple angled lenses, the machine ensures complete detection of side defects, enhances inspection accuracy, and improves overall reliability for high-density SMT assemblies.
The system provides inline measurement of UF adhesive climbing height using a calibrated side-view camera solution. It accurately detects the relative climbing height and coverage percentage of underfill adhesive, ensuring precise process control, improved bonding reliability, and stable quality in advanced semiconductor packaging.
This system provides automated conformal coating bubble inspection using AI models trained on real production images. It accurately detects bubble defects without manual rule adjustments, improving inspection efficiency, consistency, and coating quality in electronics manufacturing.
This inspection system supports multiple adhesive types, including conformal coating, UF adhesive, RTV adhesive, and heat dissipation adhesives. It ensures precise defect detection and offers optional adhesive thickness measurement, helping manufacturers maintain high reliability and consistent bonding quality.
