Introduction
"This Inline PCB Cleaning Machine with AOI equipment is specifically designed for product cleaning and solder joint inspection after the selective soldering process. Once the product enters the machine, it performs a fully automated workflow including automatic clamping, automatic cleaning, and AOI visual inspection.
The system provides precise cleaning for areas such as through-hole pins and screws, and the AOI module automatically detects defects such as solder bridging, insufficient solder, solder beads, foreign objects, blowholes, and solder joint cracks, ensuring stable and reliable solder quality.
By integrating cleaning and inspection into one machine, it significantly improves efficiency, replaces manual labor, and is ideal for high-mix, high-quality PCBA production lines."
