Troubleshooting
1. Pickup errors
1.1 Chip components
45701-D8-00
Symptom
Pickup error
occurs in all
feeders.
Pickup error
occurs in a
specific head.
Pickup error
occurs for a
specific
component.
Possible cause
The nozzle does not
reach components, or
the pickup point is not
correct.
The head offset X, Y
or Z data is incorrect.
The feeder is not
properly installed, or
the tape feeder has a
problem.
The nozzle tip does
not reach the
components, or the
pickup positions are
incorrect.
The reference pickup
vacuum level is
incorrect.
Corrective action
If the nozzle does not reach the
component, then readjust the "Z" value
on the Feeder PlateOffset screen. When
the pickup position shifts, perform
teaching for the feeder plate.
Test-mount components and adjust the
"Head offset X, Y" values based on the
results obtained.
Detach the feeder from the feeder plate
and check for tape feed. If tape feed is
not smooth, replace the feeder. Also
check that no loose chip components
remain at the feeder set position.
If the nozzle does not reach the
component, increase the "Pick Height"
value of the PICK & MOUNT
parameters in the component i
nformation. When the pickup position
shifts, perform reteaching for the pickup
position in the component information.
Increase the reference pickup vacuum
level.
