Subit Automatic Stencil Inspection: SMT Precision Choice

As a local innovative brand in Shenzhen focusing on electronic manufacturing inspection equipment, Subit has always taken "Precisely Empowering Production, Efficiently Reducing Costs" as its core, and deeply caters to the inspection needs of the SMT (Surface Mount Technology) industry. Its Auto Stencil Steel Inspection Machine is an intelligent solution for inspecting the opening precision, integrity, and consistency of steel stencils (SMT stencils). Relying on technological innovation and stable performance, it has become a core equipment for electronic manufacturing enterprises to improve production efficiency and ensure product quality.

Core Advantages: Redefining the Efficiency and Precision of Steel Stencil Inspection

1. Micron-Level High-Precision Inspection to Eliminate Production Risks

Subit's auto steel stencil inspection machine is equipped with a high-resolution industrial camera and AI visual recognition algorithm, achieving an inspection precision of ±1μm. It can accurately identify various defects such as steel stencil opening size deviation, position offset, burrs, blockages, damages, and deformation. Compared with the shortcomings of traditional manual inspection—such as strong subjectivity, low efficiency, and high missed inspection rate—the equipment can realize 100% full-size inspection, avoiding production problems such as poor solder paste printing and component cold soldering caused by steel stencil defects from the source, and significantly reducing rework costs.

2. Fully Automated Process to Improve Inspection Efficiency

The equipment integrates fully automated processes including automatic loading, automatic positioning, automatic inspection, and automatic report generation, requiring no manual intervention. For steel stencils of different specifications (supporting a maximum size of 1200×1000mm), inspection parameter settings can be completed with one-click operation. The inspection speed can reach up to 30 seconds per piece (adjusted according to the opening density of the steel stencil), and the daily inspection volume can reach thousands of pieces—far exceeding the efficiency of manual inspection, and adapting to the inspection needs of large-scale mass production scenarios.

3. Intelligent Data Management to Facilitate Quality Traceability

The equipment has a built-in industrial-grade data management system, which can store inspection data, defect images, and statistical reports in real time, and support export in Excel/CSV formats. Through data visualization analysis, enterprises can trace the inspection records, defect types, and handling results of each steel stencil, providing data support for steel stencil maintenance and production process optimization, and meeting the quality control requirements of modern production.

4. Stability and Durability to Adapt to Complex Production Environments

Relying on Shenzhen's complete manufacturing supply chain and R&D capabilities, Subit uses internationally renowned brands for the core components of the equipment (such as German lenses and Japanese motors). The machine body adopts a high-rigidity cast iron structure with strong anti-interference ability, which can adapt to complex environments such as high temperature, dust, and vibration in electronic factory workshops. The Mean Time Between Failures (MTBF) of the equipment exceeds 2000 hours, with low maintenance costs, ensuring production continuity.

Core Functions: Meeting the Actual Inspection Needs of the SMT Industry

• Multi-Dimensional Defect Inspection: Covers more than 10 inspection items including opening size, hole roundness, hole position coordinates, hole wall smoothness, and stencil flatness, meeting the inspection standards of different types of steel stencils (laser-cut steel stencils, electroformed steel stencils);

• Intelligent Calibration and Adaptation: Supports automatic focusing and automatic light source adjustment, adapting to steel stencils of different thicknesses (0.1-0.5mm) and opening densities without frequent manual adjustments;

• Defect Classification and Alarm: Allows custom defect thresholds, classifies and marks minor defects and serious defects, and triggers sound and light alarms to facilitate quick handling by staff;

• Strong Compatibility: Supports connection with MES systems and ERP systems, realizing real-time synchronization of inspection data with production management systems and improving the intelligent management level of factories.

Application Scenarios: Empowering Quality Control Across the Entire Industry Chain

Subit Auto Stencil Steel Inspection Machine is widely used in various electronic manufacturing scenarios:

• Steel stencil manufacturers: 100% inspection before delivery to ensure steel stencil products meet customer specifications;

• SMT processing plants: Inspection of steel stencils upon warehousing, regular verification during production, and re-inspection after steel stencil maintenance;
