[AI Image Inspection Case] Detection of Chipping on the Side of a Circuit Board

The AI image inspection software detects missing parts on the substrate side!

If there are chips on the substrate, they are treated as defective products. Electronic component manufacturers pay close attention to the handling of parts, but inevitably, a few defective items do occur. The defect in this case was a chip on the side of the substrate. During visual inspection, it was difficult to distinguish between the chipped area and the substrate pattern, making the inspection challenging. The goal was to supplement this difficulty with image recognition to inspect efficiently and accurately. 【Inspection Settings and Results】 Using the "Scratch Inspection" feature of EasyInspector, we inspected the chips on the side of the substrate. By tilting the substrate slightly, the chips became easier to see. When we set the detection sensitivity (luminance difference) to a strict level (10), we were able to detect the chipped area, but the substrate pattern was also detected. After further inspection, we loosened the detection sensitivity (to 20), which successfully allowed us to detect only the chips without detecting the substrate pattern. 【Software and Equipment Used】 Software Used: EasyInspector310 Minimum Size of Inspection Target: Approximately 3-5mm Number of Inspection Points: 4 Camera Resolution: EI-Scan Current inspections can be performed with the 'EasyInspector2' color package [Scratch and Object Detection].
