S3030 is a pre-programmed SMT furnace front and back SMT automatic optical inspection equipment, it is equipped with multi angle RGBW light source, 4-channel small angle 3D projection system, high-resolution high-speed camera and telecentric lens, and standard Y-axis gantry dual motor drive. The equipment adopts "2D+3D fusion inspection", which obtains three-dimensional data of components and solder joints through 3D imaging, and combines 2D planar information to achieve all-round inspection, especially suitable for high-density and miniaturized components. It can achieve 3D online automatic optical inspection, which can detect defects such as missing parts, offset, reverse, floating height, side standing, monument standing, poor solder joints, solder beads, oxidation pollution, foreign objects, scratches, etc. on SMT circuit boards.
