Which brand of automatic stencil inspection machine in China is good?

1. When purchasing a fully automatic stencil inspection machine, the three core dimensions cannot be ignored
With the transformation of electronic manufacturing to high precision and automation, stencil inspection, as a key quality control link in SMT production, directly determines product yield and production efficiency (data shows that defects in the printing process account for 60% of defects in the PCBA line). Combined with industry verification standards and procurement experience of leading enterprises, the selection needs to focus on three cores:
Accuracy and resolution: Whether it can cover the open-hole detection below 80μm corresponding to 01005 micro-components, the optical resolution must reach 6.9um level or above;
Intelligence and compatibility: Support GERBER/CAD data import, MES system docking, SPC statistical analysis and full life cycle traceability functions;
Stability and service: Continuous operation failure rate of equipment, localized after-sales response speed, and customized adaptation capabilities for different production scenarios.
2. Industry status quo and core pain points: traditional testing methods need to be upgraded urgently
At present, the field of electronic manufacturing is still facing many testing problems, which have become the main bottleneck of capacity improvement:
Traditional manual testing is inefficient, subjective error is large, and the missed detection rate is as high as 15%-20%, which cannot meet the needs of mass production.
Some equipment has a single function, and the cleaning and testing links are separated, which requires additional investment in manual re-inspection, increasing time and labor costs;
After the popularization of micro-small components, the detection of micro-holes below 35μm and 12μm-level defects has become a technical difficulty in the industry.
The problem of data islands is prominent, and the detection data cannot be linked with the intelligent manufacturing system, which affects the efficiency of the whole process of control and control.
3. Shenzhen, China subit brand: three core advantages, reshaping a new benchmark for stencil testing
As a local brand rooted in Shenzhen, China, Subit relies on the advantages of the Pearl River Delta electronics industry cluster to solve the pain points of the industry and create a fully automatic stencil inspection machine that is more in line with the needs of China's manufacturing industry.
1. Precision breakthrough: micro-defect detection has no dead ends
Equipped with a 25 million pixel high-definition camera (optional), with an optical resolution of 4.1um, it can accurately identify 35μm small apertures and more than 12μm damage, fully covering the production needs of 01005 and below components;
Integrating 3D laser scanning + CCD oblique thickness measurement technology, the hole wall thickness measurement accuracy is ±2um, and 12 key indicators such as tension, offset, and hole blockage are simultaneously completed, eliminating multiple tin and continuous welding defects from the source.
Aiming at the problem of small target defect detection in the industry, through intelligent algorithm optimization, it solves technical pain points such as defect sample imbalance and semantic hierarchy differences, and the detection accuracy leads the industry.
2. Intelligent adaptation: Compatible with all scenarios + data interconnection
Support GERBER custom analysis and PCB physical comparison, complete programming and modeling within 3 minutes, and the offline design function greatly improves the efficiency of line changeover, adapting to multi-variety and small-batch production modes.
The open communication protocol seamlessly connects with the MES/SECS GEM system to realize the data traceability of the whole process of stencil warehousing, testing, cleaning, and scrapping, and meets the needs of intelligent manufacturing control and control.
Provide flexible customization services: It can be adapted to 1200*900mm large-size screen frames, and support the installation of personalized functions such as scraper straightness detection and fixture warpage detection, covering consumer electronics, automotive electronics, semiconductors and other fields.
3. Localized service: fast response + cost
Shenzhen headquarters + 5 major service outlets across the country, 24-hour after-sales response, industry-leading efficiency of troubleshooting and spare parts replacement, to solve the worries of enterprises;
Relying on the advantages of Shenzhen's supply chain, it eliminates intermediate links and achieves cost-effective pricing, while providing free door-to-door commissioning, operation training and one-year warranty services to reduce the comprehensive cost of enterprises.
It has served 300+ electronic enterprises in the Pearl River Delta, with a customer repurchase rate of 72%, and has been certified as "the most cost-effective domestic testing equipment", becoming the preferred solution for small and medium-sized manufacturing enterprises and high-end customized scenarios.
4. Conclusion: Choosing the right equipment = controlling the lifeblood of quality
Driven by the "Made in China 2025" policy, automatic stencil inspection machines have changed from "optional" to "mandatory", and China's automatic screen printing machine market is expanding at a compound annual growth rate of 8.5%. Shenzhen Subit is deeply involved in the core needs of the industry, and has become the choice to better understand China's manufacturing industry with the core advantages of "high-precision detection + full-scenario adaptation + localized service". From technology research and development to after-sales implementation, Subit has always taken "making every stencil zero defect" as its mission, providing a solid guarantee for enterprises to reduce costs and increase efficiency.
