Semi Auto Stencil Printing Squeegee Blade Inspection Machine – Improve SMT Yield with SUBIT

In SMT production, the squeegee blade is the unsung hero of solder paste printing. Even minor edge wear, deformation, or nicks can cause insufficient solder, bridging, or uneven paste deposition—defects that directly impact PCB quality and production yield. Yet many manufacturers still rely on manual visual checks with flashlights and feeler gauges, methods that are inefficient, subjective, and prone to error.
The SUBIT SBT-SGD600S semi-automatic squeegee blade inspection machine bridges this gap, offering a cost-effective solution that balances precision, operational simplicity, and production efficiency.

How It Works

The machine integrates mechanical positioning, intelligent control, and visual assistance to simulate the actual working state of the squeegee during printing. Key components include:
00-Grade Marble Platform – With a flatness error ≤0.005mm and an extremely low thermal expansion coefficient, this platform provides a stable, vibration-resistant surface that eliminates measurement errors caused by uneven tabletops.
PLC Intelligent Control + Touch Screen – The PLC system precisely controls squeegee pressure (2–5kg standard, adjustable up to 20kg), allowing inspectors to observe blade contact under real working conditions. The 7-inch touch screen supports Chinese and English interfaces for easy operation.
High-Brightness LED Backlight – Adjustable LED illumination under the marble platform enhances edge visibility, making micro-notches, wear, and deformation clearly identifiable through light leakage observation.
Data Management – Inspection results can be manually recorded and exported via USB, with optional LAN and RS232 interfaces. MES system connectivity is also available for full traceability.
Key Specifications

Why Choose Semi-Automatic?
Compared to fully automated vision systems, the semi-automatic approach offers a compelling balance:
Lower capital investment – no expensive image recognition hardware required
Faster operator adoption – intuitive touch-screen operation with minimal training
Flexible inspection – suitable for production lines, QC labs, and R&D environments
Full traceability – data export and MES integration support modern quality management
