6. Tighten the setscrews (#1 & 5, Fig. 9) to secure the “Y” position of
the PCB.
7. Tighten the setscrew (#3, Fig. 9) on the sliding shaft holder (#9, Fig.
9) to secure ”X” position of the PCB.
8. Switch on the vacuum switch (#7, Fig. 6).
9. Hold the component to be placed using the vacuum nozzle. See
Figure 7.
10. Adjust the lighting using the adjustment knobs (#1 & 2 Fig 5) so the
image of the PCB land pattern and the image of the solder balls on
the component can be seen clearly.
11. Adjust the height of the device with the height (Z-axis) adjusting
screw (#4 Fig 5) to bring solder balls/leads into focus. Failure to
focus the component may result in inaccurate alignment.
12. Turn the “AUTO-FOCUS” feature on after the PCB and component
are focused.
13. Adjust
θ
aspect of the component by turning the
θ
adjustment knob
(#3, Fig. 6).
14. Adjust the X and Y aspects of the component by adjusting the X
and Y adjustment knobs (#5 & 6, Fig. 6).
15. When the component is aligned (See Figure 7), return the optics
housing to its retracted position. The lights will turn off
automatically.
16. Using the handle, lift the alignment apparatus upwards by hand to
release, then lower the apparatus slowly. As the apparatus
reaches the PCB, the damper will engage to ensure the component
lands softly on the PCB.
NOTE:
The alignment apparatus cannot be lowered while the
optics housing is extended.
DO NOT DROP THE ALIGNMENT APPARATUS FROM THE
UPPER POSITION.
NOTE:
When repeating operations using the same PCB and
device, steps 4 and 11 may be eliminated. However,
when changing devices, it is important to include steps 4
and 11 in the initial setup procedure.
3) Confirm that the component has contacted the PCB. Turn off the
vacuum switch (#7, Fig 6).
When repeating operations using the same PCB and device, the
mechanical stop on the right side of the alignment apparatus may
be set to ensure repeatability.
4) Return the alignment apparatus to its original position.
