■ Workflow
| Serial number | Operating Steps | Operating Procedure |
| 1 | GERBER inspection | Open the GERBER comparison and verification software, and import the stencil GERBER file, the CAD file, as well as the items to be inspected and verified. Steel mesh GERBER files: the software automatically checks and compares differences in the GERBER files, such as misalignment, missing holes, or extra holes. Dimensions and area size, along with inspection result prompts, are provided to verify that the stencil GERBER file is correct. |
| 2 | Offline Program Development | Open the programming software, input the stencil GERBER file → analyze the GERBER aperture information → automatically process according to the GERBER apertures. Group the information → Automatically set inspection parameters based on hole‑opening grouping → Specify positioning MARKs → Generate and save the program. |
| 3 | Place the steel mesh into the scanner. | Place the stencil onto the equipment’s inspection platform in the GERBER orientation → Manually or via barcode scanning, load the inspection program. |
| 4 | Program debugging confirmation | Confirm the screen frame size and MARK alignment → The equipment automatically generates tension settings and inspection programs. |
| 5 | Automatic device detection | The equipment automatically inspects the holes according to programmed procedures, checking their position, dimensions, quantity, precision, foreign objects, burrs, and damage. Micro-porosity, shape, perimeter, true roundness, tension, thickness; And output all inspection data and results, including mesh size, tension, thickness, and screen‑printing precision. |
| 6 | Test result confirmed. | Confirm the stencil inspection results → Automatically store the inspection data → Remove the stencil |
| 7 | SPC Report Generation | Using SPC software, standard SPC stencil inspection report files are automatically generated based on the test result data. |
| 8 | Data integration and upload | Open the customized MES integration and upload software; once the inspection is complete, the equipment automatically uploads the corresponding data to the management system. |
■ Product Introduction
| * | An automated stencil inspection machine is an optical measurement device that employs image‑based automatic recognition technology. It acquires parameters such as the dimensions, position, and wall thickness of stencil apertures, then compares these measurements against predefined tolerance ranges and reference values in the software to determine whether the stencil apertures meet specification requirements. |
| * | Traditional manual inspection methods cannot ensure inspection accuracy, fail to provide precise measurements and comparisons, lack data recording and analytical benchmarking, and are unable to conduct rigorous studies on the impact of different stencil‑opening processes on product quality during use. |
| * | The equipment is easy to operate, and the inspection process is fully automated, which not only significantly enhances both accuracy and speed but also eliminates human‑induced variability, providing direct, objective, quantitative data for assessing the quality of steel stencils. |
| * | Primarily aimed at newly introduced steel stencils, this process involves measuring and evaluating the accuracy and appropriateness of stencil apertures, as well as monitoring the quality of in‑use stencils to identify potential issues early and prevent batch‑level process problems caused by stencil defects. |
| * | Automatic tension testing and recording, test report storage, and monitoring of stencil precision changes; |
| * | Inspect and monitor the mesh thickness of both stepped and standard steel screens to ensure the quality of incoming materials and the accuracy of the manufacturing process. |
| * | By leveraging PCB GERBER files and stencil GERBER/CAD files, a multi‑check functionality enables verification and validation of the stencil file’s design integrity, allowing you to confirm offline in advance whether the stencil GERBER file is correct. |
| * | Enhance automated control capabilities to promptly prevent, detect, and manage quality and efficiency issues arising from stencil‑related problems. |
| * | Improve the stencil aperture‑forming process, resolve printer‑related challenges, and enhance the first‑pass yield of SPI inspection. |
| * | Detailed recording of inspection data and generation of various types of SPC reports to enhance process analysis and support continuous improvement of manufacturing processes. |
