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.

1. Solder Inspection
● Solder Inspection consists of 3 mode. Which are:
Terminal Reference: Solder height qualification are based on the
height (%) between lead terminal & PCB surface
Base Reference: Solder height qualification are based on the height
(um) measured from PCB surface
