Check procedure:
When the Z-slide shaft is rotated about 360 degrees, the diffuser should not contact the nozzle outer surface.
(LAIC head only)
Turn the Z-slide shaft 360 degrees and check that the φ22.5-hole in the diffuser is not in contact with the
nozzle outer surface.
Adjustment procedure:
Temporarily secure the diffuser support to head bracket IC with SEMS cap (a). Using SEMS cap (b), install
the raxa paper base assembly to sandwich the diffuser. At this time, adjust the position of the diffuser
support to allow no clearance between the raxa paper base assembly and the bottom surface of FMLA; then
secure it in position. (See the illustration below.)
Adjust the position of the diffuser so that it does not contact the nozzle outer surface; then, secure it in
position. At this time, align the end face of the raxa paper base assembly with that of FMLA so that VCS
will not pick up the image of the bottom surface of FMLA. (See the illustration below.)

Place the camera adjustment jig on the top surface of the calibration block, facing its etching surface down.
Lines up to 2 on the etching surface of the camera adjustment jig must be clearly visible.
Loosen six SEMS cap bolts (1) that secure the camera, move the camera up and down, and when lines up to 2
on the etching surface are clearly visible, secure the camera in position.
Lines up to 2 must be

Concerned with camera recognition accuracy, it greatly affects placement accuracy and component pickup
reliability.
– Degraded placement accuracy when BOC mark is used
– Degraded bank recognition accuracy and teaching accuracy, resulting in poorer pickup reliability
