The S3016 ultra 3D AOI system inspects THT components, THT solder joints, press-fit and SMD components shadow-free and at high precision thanks to innovative 3D camera technology on the underside of the printed circuit board. Conductor plates as well as inspection objects on workpiece carriers are inspected at high speed in 2D, 2.5D and 3D. As a result, the S3016 ultra stands for maximum defect detection and highest throughput. The images that have been already taken are evaluated while the camera module continues to process, resulting in a critical inspection speed time advantage. Different lighting can be used flexibly and so provide test results in excellent image quality. Its wide scope during transport is unique, allowing an upper transport clearance of up to 200 mm. Return transport of the manufactured products can be integrated as a standard option.
