The AOI 3D TR7700QI combines the latest 2D and 3D technologies based on fringe pattern projection to revolutionize PCB assembly inspection. Versatile programmable 3D digital fringe pattern technology covers a wide inspection range with great precision, revealing even the smallest coplanarity defects and weld joint problems. Ensure the quality of weld joints using IPC compliant 3D weld weld inspection. By checking fillet shape, the TR7700QI 3D AOI can detect insufficient solder volume, pads not wet or dry.
