B-type Algorithm - Joint

6. Tip Length (%)

● The lead tip location is always fall at the end of lead box from

the direction body box to lead box

● Tip Length is the selected region to inspect lifted lead and

missing lead

B-type Algorithm - Joint

7. Lead Height (um)

● To pre set the height for the lead.

● Need to use this value during lifted lead inspection.

8. Lifted Lead Inspection

● Relative - Software will calculate the average height for each

lead and used it as the reference height for lifted lead

inspection.

● Absolute - Lead Height (um) that we keyin will be used as the

reference height for lifted lead inspection.
