checking the object
· Checking sequence
1 Determine the center points (K1 to K4) of those leads which are in a line to
inspect.
2 Check for any bending of leads that may have occurred by comparing the
shortest and longest P measurements with variations in those measurements
within the reference image.
3 Check the length of the leads, which is measured based the direction specified
before, by comparing the shortest and longest L measurements against those
within the reference image.
