Revolutionizing PCB Defect Inspection: The Role of AI and Advanced Imaging Technology
The competitive landscape of Taiwan’s PCB industry underscores the critical importance of automated optical inspection (AOI) equipment. AOI systems are pivotal in enhancing production capacity and improving defect yield rates by integrating seamlessly into manufacturing processes without halting operations. This technology represents a substantial investment, typically comprising about 15% of total expenditure in PCB manufacturing.
The Challenge of Overkill in Traditional AOI Systems
Traditional AOI employs automated visual inspection to scan PCB surfaces and identify defects such as short circuits, copper inconsistencies, open circuits, nicks, burrs, solder slag, missing components, or deflections using advanced image processing algorithms. However, the extremely high yield requirements for PCBs lead to overly sensitive equipment calibration, resulting in a 70% overkill rate—incorrectly flagging defect-free products as faulty. This necessitates secondary manual verification to filter out false positives before products can proceed further down the production line.
