Product overview
The Solder Paste Inspection (SPI) Machine is an advanced inline inspection solution designed to ensure high-quality solder paste printing in SMT production. By capturing precise 3D images and analyzing solder paste volume, height, area, and shape, the system helps manufacturers detect and correct printing defects early in the process — before component placement.
With its professional optical design, powerful data processing, and intelligent software algorithms, this SPI system provides fast, accurate, and reliable inspection results for both high-mix and high-volume manufacturing environments.
