2.12.4 PCB Camera
The PCB vision module uses fiducials on the PCBs to determine:
– the position of the PCB, its rotation angle, and the PCB delay.
The PCB vision module also uses fiducials on the feeder modules to determine the exact pick-up
position of components, which is particularly important for small components.
