Wistron has adopted AI technology to inspect defects of products at three of its factories and will extend such inspection to other plants, according to company senior software manger Liang Wei-quo.
Digitimes has reported that the AI-based defect inspection has been adopted for SMT (surface-mount technology) and DIP (dual in-line package) lines for producing notebooks and servers mainly.
Automatic optical inspection (AOI) may have high efficiency, but many manufacturers set AOI parameters at high levels in order to achieve high yield rates, resulting in over-sensitivity of the machine, and thus manual work is needed to double check the products for misjudged ones.
