The TR7700QI 3D AOI combines the latest of 2D and 3D technologies based on digital quad fringe pattern projection to revolutionize PCB assembly inspection. The versatile programmable 3D digital fringe pattern technology covers a huge inspection range with great accuracy, revealing even the smallest coplanarity defects and solder joint issues.Ensure the quality of solder joints using IPC-compliant 3D solder filet inspection. By checking the filet shape, the TR7700QI 3D AOI can detect insufficient solder volume, non-wetting and dry pads.
