What is SMT automatic optical inspection machine
What is SMT automatic optical inspection machine The SMT automatic optical inspection machine (AOI) is an inspection device based on optical principles, mainly used for automatic inspection of surface defects of PCBA (printed circuit board assembly) during the SMT (surface mount technology) production process. The following is a detailed introduction to the SMT automatic optical inspection machine: Definition and principle of SMT automatic optical inspection machine SMT automatic optical inspection machine, referred to as AOI, uses high-resolution cameras and advanced image processing algorithms to perform a full range of visual inspections on the surface of PCBAs. The camera automatically scans the PCB, collects images, and compares the tested solder joints with the qualified parameters in the database. After image processing, various defects on the PCBA can be quickly and accurately detected. Main functions of SMT automatic optical inspection ...
