a. Pin Mode
● Green Box - Green box used to inspect the existing of pin.
● Magneta Box - Region within green box and magenta box use to inspect
the existing pin
b. Box Size & Box Offset
● To adjust the size and offset for pin inspection box.
c. Pin Follow Locator
● To allow the pin inspection box follow the locator
d. Mask Pin Area
● This is to mask the pin area (Magneta box) from solder inspection.
e. Pin Image Plane
● These are the types of 2D Lighting. Select the one with having highest
contrast among pin region and the background.
f. Pin Grey TH Direction
● Greater Than - Pass if Grey Thres measured > Pin Grey Thres set.
● Smaller Than - Pass if Grey Thres measured < Pin Grey Thres set.
g. Pin Grey TH
● To adjust the Grey Thres for the pin inspection.
h. Pin Coverage TH(%)
● To adjust the pin coverage Thres to pass the pin inspection.
i. A.C Pin
● Tick this to adjust the contrast for the selected image plane.
● If contrast set to 50 to 200:
Remain the Greyscale Become 255
Become 0

a. Hole Solder Mode
● Average - pass criteria is referring to the grey scale threshold range set
● Coverage - pass criteria is referring to the outer solder coverage
threshold set.
b. Box Size & Box Offset
● To adjust the size and offset for Hole Solder inspection box.
c. H. Solder Segment Mode
● Circle - Use circle region in the calculation
● Segment - Use 8 segment region in the calculation
d. H. Solder Image Plane
● These are the types of 2D Lighting. Select the one with having highest
contrast among Hole Solder region and the background.
e. H. Solder Grey Thres
● Hole Inspection will fail if the measured Grey Thres on that particular
pixel out of the Threshold range set.
