a. Solder Inspection
● To enable the box offset into symmetric direction only.
b. Joint Size & Joint Offset
● To adjust the size of Joint Inspection Box & offset of Joint Inspection
Box.
c. Joint Image Plane
● These are the types of 2D Lighting. Select the one with having
highest contrast among pin region and the background.
d. Joint Grey Thres
e. Joint Coverage Thres
● To set the percentage to pass the joint inspection.

Grey Thres
Measured Grey Thres
PASS FAIL
Pass Criteria for single pixel:
a. Measured Grayscale < Joint Grey Thres
b. Solder Height (%) > Joint Height Thres (%).
The overall pass criteria depends on:
Joint Coverage (%) > Joint Coverage Thres (%)
