U-type Algorithm - 3D Multijoint

214

a. Lead Relocating Mode

● Lead relocation is used to relocate the lead by using lead box

after locate body successfully.

● This feature will increase cycle time.

b. 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

a. Lead Height (um)

● Lead relocation is used to relocate the lead by using lead box

after locate body successfully.

● This feature will increase cycle time

b. 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.
