1.Make sure that there is no
clogging, wearing down, or
chipping of the nozzle tip.
Replace the nozzle if you find
anything wrong with it.
2.Check for a sliding error of the
nozzle holder. Modify if
necessary.
3.Check whether the nozzle is
magnetized or not .
Demagnetize it if magnetized.

Check the vacuum pressure
(appropriate pressure:-87 to
-100kPa). If it is not within the
value, adjust the pressure.
Check the pickup position setting.
Adjust if incorrect.

1.Check whether the placement
retainer is set up properly. Fix it
if necessary.
2.Check whether the vacuum
breaking pressure is set properly.
Adjust it as needed.
3.Check whether XY coordinates
of the production data is set up
properly. Adjust it if not correct.
4.Check for the mounting timer
value.
Check whether component outline
and thickness, and dimensions of
each electrode are input correctly.
Adjust them if incorrect.

Check whether the PCB support
pins are properly positioned.
Adjust if necessary.
(Check that the PCB support pin
does not interfere with the
component)
Check the PCB upper surface
warpage.
If it warps too much, do not use it.
Check whether the placed
component height is set up
properly.
Fix it if necessary.
