AOI is equipment based on optical principles for detecting common defects encountered in welding production.

The AOI software features a comprehensive verification function that reduces inspection false positives and ensures the detection program is defect-free. It can inspect stored defective samples, such as those kept at the repair station, as well as blank printed circuit boards with solder paste printed. During the optimization phase, the reason for spending time in this area is to ensure no defects slip through. All known defects must be inspected while minimizing the number of allowable false positives. When adjusting any program to reduce false positives, it is necessary to check whether previously identified genuine defects have been confirmed by the repair station. Through comprehensive verification, the quality of the inspection program is ensured for specialized manufacturing and verification, while also tracking false positives.
