AOI inspection for coating<\/strong><\/h2>\n

AOI (Automated Optical Inspection) for coating is an advanced inspection method used to automatically check the quality, coverage, and consistency of \u30b3\u30f3\u30d5\u30a9\u30fc\u30de\u30eb\u30fb\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0<\/strong><\/a> on PCBs. It is widely used in modern PCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong> \u305d\u3057\u3066 SMT\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong> lines to ensure high accuracy, repeatability, and efficiency in quality control.<\/p>\n

How AOI inspection works<\/strong><\/p>\n

In coating inspection, AOI systems use high-resolution cameras, lighting (often including UV light), and image-processing software to analyze the PCB surface. The system compares captured images with predefined standards or CAD data to determine whether the \u30b3\u30f3\u30d5\u30a9\u30fc\u30de\u30eb\u30fb\u30b3\u30fc\u30c6\u30a3\u30f3\u30b0<\/strong> has been applied correctly.<\/p>\n

In many \u30bf\u30fc\u30f3\u30ad\u30fcPCB\u30a2\u30bb\u30f3\u30d6\u30ea<\/strong><\/a> processes, AOI is integrated inline, allowing real-time inspection immediately after coating.<\/p>\n
