How to choose the right stencil inspection machine? Subit teaches you to do it in one stop!

1. First clarify: when selecting steel mesh testing machines, the core is "what problems to solve"
In SMT production, the opening accuracy, blockage, and deformation of the stencil directly affect the welding yield (for every 1% increase in defect rate, the annual loss may exceed one million). Ask yourself 3 questions before choosing equipment:
Inspection scenario: offline sampling or online full inspection? (Mass production is prioritized online, small batches can be offline)
Stencil specifications: maximum size (common 508×610mm/610×710mm), minimum hole diameter (below 0.1mm requires high-precision equipment), mesh thickness (0.1-0.3mm)
Core requirements: Only detect blockages/deformations? Or do you need to measure the cutout size, spacing, and verticality? (Automotive electronics and medical electronics have higher dimensional accuracy requirements)
2. 5 key selection criteria, Subit will take you to avoid pitfalls
1. Detection accuracy: "micron-level" is practical enough
Core indicators: repeatable positioning accuracy ≤± 1μm, measurement accuracy ≤±2μm (lower than this standard, small holes below 0.1mm are easy to miss)
Subit advantages: Adopting imported CCD vision system + AI edge algorithm, the minimum detection aperture diameter is up to 0.08mm, and the mesh deformation recognition accuracy is 0.01mm, meeting the needs of high-precision electronic production (such as mobile phones, drone motherboards)
2. Detection speed: match the production line beat
Key parameters: Inspection time of single stencil (offline machine≤3 minutes, online machine≤1 minute / sheet)
Pitfalls: Don't just look at the "fastest speed", but also look at the "stable speed" (some devices sacrifice accuracy for speed, and the data fluctuates greatly)
Subit advantages: The inspection speed of online models is up to 45 seconds/sheet, supporting 24-hour continuous operation, and adapting to the production capacity of 12,000 points/hour of SMT production lines
3. Compatibility: "One machine for multiple uses" saves money
Support: different sizes of stencil (Subit equipment can be compatible with 300×300mm-710×810mm full specifications), different mesh materials (stainless steel, nickel alloy), different opening types (round, square, special-shaped holes)
Bonus: Whether it supports stencil ID binding and testing data traceability (convenient for quality traceability and meeting the requirements of ISO system)
4. Ease of operation: Reduce training costs
Key functions: graphical operation interface, automatic calibration, one-click detection, fault alarm (reduce dependence on technicians)
Subit advantages: Equipped with the self-developed Subit OS system, it supports Chinese/English switching, novices can get started in 1 hour, and the test report is automatically generated in Excel/PPT format, no need for additional sorting
5. After-sales service: "localization" is reliable
Core guarantee: response time (door-to-door within 24 hours), warranty period (industry generally 1 year, Subit extended to 2 years), spare parts supply (Shenzhen headquarters + 5 major service points across the country, spare parts arrival ≤48 hours)
Pitfall: Beware of "low-priced equipment" - there is no localized service, and the loss of 1 day of downtime after failure may exceed the value of the equipment itself
3. Subit brand: Shenzhen's local powerful manufacturer, 3 core competitiveness
Technology precipitation: 10 years of experience in the research and development of steel mesh testing equipment, 23 patents have been obtained, and the core team is from Huawei and Han's Laser
Customization capabilities: Interfaces can be customized according to customer production lines (such as Panasonic and Fuji placement machines) to achieve seamless docking
Customer verification: Served 500+ leading companies such as BYD, Luxshare Precision, Goertek, etc., delivered more than 2,000 equipment, and the defect rate feedback ≤0.3%
Fourth, common selection misunderstandings, and finally focus on them
❌ Just look at the price: most of the low-priced equipment is an assembly machine, with poor accuracy and short life (the core components need to be replaced after an average of 2 years of use, and the hidden cost is high)
✅ Prioritize "cost-effectiveness": Subit equipment is priced at only 60% of imported brands, but the accuracy and speed are the same, and the warranty period is longer
❌ Neglecting data traceability: Devices without traceability capabilities cannot meet the compliance requirements of automotive electronics, medical electronics, and other industries
✅ Identify "intelligence": Subit equipment supports MES system docking and real-time upload of inspection data to achieve whole-process quality control
