Online 3D SPI Technology Enhances SMT Printing Quality GDK-S2000 Enables High-Precision, Real-Time Solder Paste Inspection

  As electronic products continue to evolve toward higher density and miniaturization, the demands on solder paste printing quality in SMT production lines are becoming increasingly stringent. As a critical upstream process, solder paste printing directly affects placement accuracy, reflow performance, and overall production yield. In this context, online 3D SPI (Solder Paste Inspection) systems are rapidly becoming standard equipment in modern SMT lines.

Shenzhen Hetian Gude Automation Equipment Co., Ltd. has introduced the GDK-S2000 online 3D solder paste inspection system, providing manufacturers with a high-precision solution for real-time monitoring and control of solder paste printing quality.

The GDK-S2000 integrates a high-speed digital CCD camera with an industrial telecentric lens and a 3D grating projection system to achieve shadow-free 3D inspection. The system accurately measures key solder paste parameters including area, volume, height, shape, and offset, with height measurement accuracy reaching 1 μm, meeting the inspection requirements of 0201 and finer components.

To address challenges such as large PCB formats and board warpage, the GDK-S2000 features real-time PCB warp measurement and compensation. It supports PCB sizes of up to 2000 × 500 mm, making it suitable for a wide range of SMT production scenarios. The system also supports Gerber and CAD file import, offline programming, and SPC data analysis, enabling engineers to trace defect trends and continuously optimize printing processes.
