AOI (automatically optical inspection) is a means of automatic detection through optical system imaging. AOI is one of many automatic image sensing detection technologies. How to obtain accurate and high-quality optical images and process them at the core technology points?

AOI detection technology emerges as The Times require, with high integration and refinement of electronic components, higher detection speed and efficiency, and zero defect detection. The biggest advantage of AOI testing is to save manpower, reduce cost, improve production efficiency, unify testing standards and eliminate human interference, ensure the stability, repeatability and accuracy of testing results, timely find product defects, and ensure shipment quality. In the artificial intelligence technology and the development and progress of big data today, AOI detection is not only a test equipment, classifying and statistics, the result of the bad bad causes, can be found in process improvement and production yield ascension also is gradually play a more important role, therefore, can be expected future AOI inspection technology in the semiconductor and electronic circuit testing will play an increasingly important role.
