9.9 Optical PCB Position Recognition (PCB Vision

System)

The optical PCB position recognition or the PCB vision system registers the exact position of the PCB by

measuring the fiducials and then determines the offset in the x and y directions, the angle of rotation with

respect to the direction of PCB transportation and the shear of the PCB. Rejection markings (ink dots) are

also registered by the PCB vision system.
