Judge Size Condition
Set whether to judge as an NG result if both the X and Y sizes of the detected foreign object are judged
to be NG, or to judge as an NG result when even one of the X or Y sizes is judged to be NG when
judging foreign object inspection.
Judge Size X Min. (mm)
An OK result is judged if the X direction size of the detected foreign object is less than this value.
Judge Size X Max. (mm)
An OK result is judged if the X direction size of the detected foreign object is greater than this value.
Judge Size Y Min. (mm)
An OK result is judged if the Y direction size of the detected foreign object is less than this value.
Judge Size Y Max. (mm)
An OK result is judged if the Y direction size of the detected foreign object is greater than this value.

Detection data
Position Align dX =, dY = : These are the values corrected with position correction.
Threshold No. : This is the threshold No. applied to inspection.
MaXLength X = : This is the maximum detection width X.
MaXLength Y = : This is the maximum detection width Y.
Foreign Level = : This the maximum foreign object level.
2. Take a note of and check the detection data, and then press the [End] button.
3. If the test result is not judged correctly, review all parameters while referring to the detection data.
TIP
Foreign object check steps can be created for all views by pressing the [Edit Assist] button and selecting the "Foreign
