The Automated Optical Inspection (AOI) system is primarily employed to detect defects in PCB production, such as gaps, short circuits, and open circuits. With the shift from traditional mass production to flexible production with a greater variety of products in smaller quantities, the complexity of defect detection has increased. In response, MiTAC has aimed to establish a model and reduce false positives with minimal data, resulting in the development of an automated optical inspection rejudgment system.

MiTAC Automated Optical Inspection (AOI) system is currently deployed at Pronology Services Inc. and NEXCOM International Co., Ltd. By collecting data on both good and defective products from the AOI machine, a model has been established. This model successfully infers and analyzes potential defects during subsequent production processes, aiding in the reduction of false positives and minimizing the need for manual rejudgment.
