With the continuous development of the manufacturing industry and the improvement of product fineness, AOI optical inspection equipment needs to have higher accuracy and faster speed to meet the high efficiency and high precision inspection needs on the production line. With the development of artificial intelligence, machine learning and other technologies, AOI inspection equipment will be more intelligent, and can continuously improve the accuracy and stability of detection through self-learning and upgrading, while reducing the false detection and missed detection rate. In the future, it is believed that AOI inspection equipment will be further integrated, integrating a variety of testing technologies into one device, achieving multi-angle and multi-level testing, and improving the comprehensiveness and accuracy of testing.
