LaserVision Compact Twin

AOI-System LaserVision Compact TWIN

Inspection of double-sided PCBs

The LaserVision Compact Twin is based on the approved LaserVision Compact. By the integration of a second camera head the system is able to check double-sided PCBs and THT soldering points simultaneously from above and below during the running production process.

The LaserVision Twin comes with two image processing computers. They provide for a real parallel processing of the generated test data which are automatically brought together to optimize the repair handling.

Furthermore the high test speed is based on an intelligent control and the coordination of the two sensor modules at the admission and exposure moment.
