Abstract

An automatic optical inspection system includes a first AOI machine and a second AOI machine, and the second AOI machine is electrically connected to the first AOI machine. The first AOI machine is configured to use a first resolution to inspect an object, so as to detect a possible defective region(s) of the object. The second AOI machine is configured to use a second resolution higher than the first resolution of the first AOI machine to inspect within the possible defective region(s) only, so as to detect whether there is/are any defect(s) within the possible defective region(s) of the object.
