Step33: Right-click on Adjust and select Copy. The same parameter will be copied in 2 of NUM....
Step34: Select 2 of NUM... and select Area from the Defect drop-down list.
Step35: Adjust the size of the inspection window for Area to detect the fi ducial mark automatically.
Ideal window size is about three times bigger than the fi ducial mark size.
CAUTION
The larger inspection window can inspect the fi ducial mark even if it is out of the target
position. However, it takes longer time to inspect it and some PCB pattern might be
misjudged as a fi ducial mark.
Step36: Select Adjust and press Inspect. Pink lines crossing the center of the fi ducial mark appears if the
search is successful.
Step37: Press Update. The dialog shown in Figure 1-22 appears. Press OK.
