OVERVIEW OF AOI USE IN SURFACE-MOUNT TECHNOLOGY CONTROL
Abstract
Surface-mount technology is now widely used in the production of printed circuit boards in the electronics industry and has gained many supporters. The miniaturization of electronic components has forced the introduction of machines for visual inspection of assembly correctness, which is more accurate and faster than the human eye, magnifier or microscope. Automatic Optical Inspection (AOI) is a control process that detects defects and errors in the initial PCB manufacturing process. It has become an indispensable element of contract assembly, increasing the quality of services offered and production efficiency. It uses new designs of measuring heads, miniaturization of equipment, software processing the obtained images of boards, and complicated image transformation algorithms.
