modusAOI MLD1200 V2.0-DS

Offline double-sided inspection

The MLD1200 V2.0-DS is an offline dual AOI system for the inspection of assembled printed circuit boards from both sides at the same time. It has two multi-LED illuminated image scanners as well as our patented parallax-free lenses. It includes modus control units with the latest modus software. An optional Trolley is available.


Dual system for double-sided simultaneous inspection for both sides 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.
