1. Everyone in the industry knows that the AOI (Automated Optical Inspection) system has become ubiquitous in SMT (Surface Mount Technology) assembly production lines, supplanting manual visual inspections of yore. AOI harnesses imaging technology to assess whether the tested object conforms to predefined standards, detecting disparities between the object and the standard image.
2. Initially, AOI primarily served to uncover defects in surface printing post-IC (Integrated Circuit) packaging. However, technological advancements have broadened its scope, allowing it to scrutinize component assembly on PCBs within SMT lines or verify the solder paste’s compliance post-printing.
3. The foremost advantage of AOI lies in its capacity to supplant manual visual inspections both pre and post-SMT processes, offering a more precise evaluation of SMT components compared to human inspection. Nevertheless, akin to human vision, AOI predominantly facilitates surface-level inspections; hence, it adeptly evaluates visible features. However, it may falter when discerning obscured regions beneath or along the edges of components.
4. Admittedly, many AOIs now boast enhanced capabilities to detect IC pin misalignment and feature augmented camera angles for concealed components. Despite these advancements, achieving a 100% inspection rate remains elusive, as attaining optimal efficacy proves challenging.
