3.2.2 Edit Fiducial
PCB will be fixed manually by the magnetic pin or bars and you also need to set
a fiducial for helping recognition. Some tips for setting fiducials:
1. Fiducial requirement: round shape, it could be pads or holes with high contrast to
the surrounding area (observed in the camera). You will hear a ticking sound if the
machine fails to recognize fiducials, you can try to replace to a more suitable one. It
will be generated as fiducial once it succeeds.
2. Please avoid any similar round shapes near the fiducials to avoid confusion,
otherwise the machine will take the other one as a fiducial.
3. Inaccurate setting of fiducials will result in overall offset in the same direction.
4. In Step1, if it’s not easy to ovserve the center of the component, please press the
button to move to next component until you can clearly align the center of a
component.
5. If the fiducial cannot be successfully recognized during placement, you can adjust
the camera threshold.
