Saving data
To enable the bad mark recognition process, you need to turn ON the corresponding soft
switch.
Input the PCB bad mark
position (coordinates).
Input the pattern bad mark
position
Created on
NPM-DGS.
Recognition Test
Teaching is complete.
When partial defect occurs in the produced PCB in the middle of the process, if a bad
mark is put on it, you can skip placement on that pattern.

■If the bad mark is not located
near the center
●Align the cross line center to the
bad mark center.
