Figure 1 is an illustration of proper lead to pad alignment in the vision system with the leads (dark)
properly centered over the pads. No vision adjustment is required in this case. Figure 2 is an illus-
tration of incorrect lead to pad alignment in the vision system due to theta error.
16. If the leads and pads are not aligned in the vision system after alignment at board level, loosen (but
do not remove) the two 1.5mm set screws (E) which hold the two Vision Adjustment Disks (F) in
place.
17. Rotate the two disks slightly until component part is aligned.
18. Increase the zoom lens magnification to check your work. Increase magnification to maximum.
19. Tilt field of view up and down to insure leads are 100% in center of pad. Viewing a few leads under
high magnification may reveal minor errors not seen while aligning the entire device.
20. Slowly and carefully retighten the set screws while continuing to view the alignment. This will insure
that no movement of the cube occurs while tightening the screws.
21. Click on the Home Z/Vision Axis button (G).
