Description
Stencil Inspection Machine Overview
This Stencil Inspection Machine is an intelligent system for detecting stencil defects and verifying quality before production. It analyzes aperture size, shape, position, and stencil tension, providing complete data to ensure consistency. With optional high-resolution optics, it can detect openings as small as 40 × 40 μm, making it suitable for advanced SMT processes. The system also integrates process analysis tools, including Gerber-to-stencil comparison and PCB physical scanning. By identifying risks early, this machine prevents costly rework and improves solder paste printing reliability. Designed for speed and precision, it is an essential part of modern stencil management and SMT quality assurance.
Key Features of the Stencil Inspection System
Multi-Level Detection Accuracy

The grouping and grading method applies different inspection parameters depending on stencil size and component type. This ensures both standard and high-precision components are measured with the right accuracy, improving defect detection and reducing false judgments.
Advanced Process Analysis
By comparing stencil data with PCB Gerber files and physical scans, the system helps engineers find mismatches in aperture design and positioning. This proactive analysis prevents solder bridging, insufficient printing, and other defects before they occur.
Comprehensive Tension Testing
Built-in high-precision tensiometers allow automatic testing of stencil tension at multiple points. With ±1N.cm accuracy, this ensures stencils remain within optimal tension ranges, maintaining printing quality across production cycles.
