Editing Fiducials
You can edit fiducials defined for your workpiece at any time. You may want to edit fiducials if the
system fails to find too many of them during production runs. The procedure below is a reference
procedure and does not need to be performed now.
To edit fiducials:
Using Model Finder
1. Load the workpiece board.
2. In the Programming Window, make sure that the name of the pattern containing the fiducials
you wish to edit appears in the
Pattern Name text box.
> If it does not, click on the arrow next to the
Pattern Name text box and select the pattern
from the cascading menu.
3. From the
Edit menu select Edit Fiducial Info.
> A Teach Window opens.
> The dispensing head moves to the fiducial location.
4. Select
Model Finder.
5. Click on
Next.
6. Use the Position Controls to find your new fiducial.
> Adjust the
Model Size parameters if necessary.
> Adjust the
Accept Threshold and Confusion Threshold if necessary.
> Refer to Online Help for definitions of
Accept Threshold and Confusion Threshold.
7. Click on
Teach.
8. Test the fiducial by clicking on
Find Fid.
> The Test Results indicate if the fiducial was found or not, its found coordinates, how
certain the system is that it has found the correct fiducial, and how long it took to locate
the fiducial.
9. Click on
Done.
This concludes the tutorial on editing fiducials.
