modusAOI S3-IDN-R

Double-sided inspection

The dual AOI system is designed for simultaneous inspection of both top and bottom side. The system has two multi-LED illuminated scanner units as well as our patented parallax-free lenses. It includes modus control units with our established modusAOI software. The transport module has a system length of 1200mm (47.2 in.) The system can be built with a return conveyor if needed.


System for double-sided simultaneous inspection of printed circuit boards.

Combination of different inspection tasks such as SMD placement, THT solder joints, conformal coating and full screening for solder beads (solder balls).

Capture of any number of barcodes and data-matrix codes on the multi PCB.

Shows the test result of both sides at once.
