B-type Algorithm - Foreign Material
4. Size Thres (um)
● Minimum length and width to detect the foreign material.
5. Mask Width Expand (um) & Mask Length Expand (um)
● To adjust the mask area size.
● Mask area = Area without inspection
● The green box is the masking area.
6. Include EPad Checking
● Tick this if you have the *.epad file in C:\cpi\cad
7. Foreign Margin Only & Foreign Margin Size
● Mask component body at CAD position & actual position (with
offset x, y and skew)
● Mask pads with slightly extension
● Dilate the masking to another buffer. Mask all the pixels that are
not in dilated masking.
● To cater nearby component which included in search area
