The automatic optical inspection machine is a high-tech equipment used for detecting and identifying defects or errors in manufactured products. These auto optical inspection machines utilize high-resolution cameras, coupled with sophisticated image processing algorithms, to scan and analyze components on printed circuit boards (PCBs), semiconductors, and other intricate assemblies. SMT AOI machine uses advanced imaging technology to examine components and ensure they meet quality standards without human intervention. The implementation of AOI technology enhances production line efficiency by providing immediate feedback, reducing scrap rates, and improving overall yield.
