Setting error
in Part data.
Specify the appropriate nozzle size and
cam speed settings using the Tech
Report issued by Fuji as a reference.
If accuracy deviations or defects are
occurring for a specific part, decrease
the XY table speed setting in the Part
data where the problem is occurring.
Check for errors in the part height
information.
Check the backup pin heights, quantity,
and configuration, and verify that the
panel is flat.
Check for a problem with the Proper
data Z0 (0.3 mm push in).
Check for the reference and followup
rails' flatness problem.
Replace mechanical valves where the
spool motion is not smooth.
Adjust the vacuum break lever position
and the speed controller.
(1) Use the nozzle check command to
check for bent nozzles.
(2) Verify that the nozzle spring-back
motion is smooth.
(3) Verify that the nozzle is not clogged.
If a problem is found with any of the
above, replace the nozzle.

Cause Remedy Remarks Ref. Page
Unsuitable nozzle size, part weight, and cam
speed, etc., settings can result in an
insufficient holding force when handling
parts, causing nozzle and part slippage.
The Fuji Tech Report is meant for reference
purposes only. The recommended cam
speed may be different even if the part shap
is the same.
An unsuitable XY table speed can apply a
force which exceeds the holding capacity of
the part's solder, resulting in position
deviations.
Solder adhesion decreases when it dries.
Therefore, the sooner placement occurs after
printing, the better.
"Missing parts" conditions may occur if there
is an error in the part height information, or
in the table reference height Proper
data.
Fuji recommends actually measuring the part
height, and entering the measured value in
Part data.
A bent or stuck nozzle will make it impossible
to place parts properly.
A misalignment between the ST9 nozzle
down limit and the panel height can prevent
the part from being pressed onto the board
properly, and it may become impossible to
maintain accuracy.
Note: Machine adjustments can be performed
only by those with a Level 3 training.
Note: Machine adjustments can be performed
only by those with a Level 3 training.
A malfunctioning vacuum break may affect
placing accuracy.
Note: Machine adjustments can be performed
only by those with a Level 3 training.
The solder printing condition or dryness can
cause part deviations during board
conveyance, or can affect the self-alignment
at reflow operations.
Solder adhesion weakens when the solder
dries. Therefore, the sooner placement
occurs after printing, the better.
Improper reflow conditions can cause self-
alignments and tombstoning.
Provide a profile in which the temperature is
increased evenly over the entire board. If the
solder's melting speed differs from point to
point, parts will be pulled toward the solder
which melts first.
Failure to level the machine base after the
machine has been moved, etc., can affect the
XY-table flatness, making the current Prope
data settings unsuitable.
Verify that the machine base is level
(if not, level it).
Measure the X0/Y0 and camera
resolution.
Perform a calibration using a PAM part.
Check the solder condition after printing.
Check the reflow temperature profile.

Feeder top-film

Improper feeder

Feeder set
improperly
Take-up will be abnormal if the top film is
not set correctly.
Set the top film correctly.
(Point) The top-film is not being peeled off at
the pickup point. Peel off the top-film
and verify that the take-up roller and
reel are set
correctly.
The top-film is not being peeled off at
the pickup point. Peel off the top-film
and verify that the
take-up roller and reel are set correctly.
A clogged tape leaf slit can back up the top-
film and prevent proper take-up.
Clean the tape leaf slit.
Take-up resistance increases if the take-up
roller fails to rotate smoothly.
Clean the inside of the take-up roller.
A deformed take-up spring reduces the take-
up force.
If the take-up spring is deformed,
replace it.
An excessively low reverse-direction torque
will reduce the take-up force.
Check the take-up reel's reverse-
direction torque.
If clearly low, replace the take-up reel.
Damage may occur or take-up may not be
correct if the take-up reel or aluminum
bracket is bent. This may also interfere with
surrounding feeders.
If the take-up reel or aluminum bracket
is deformed, replace it.
• An incorrect tape and feeder width or feed
pitch will prevent parts from being fed to
the proper position.
• A tape leaf which is unsuitable for the
nozzle size will cause parts to spring off the
tape.
• Check the tape and feeder feed
pitches, and set the tape on the
correct feeder.
• Use a tape leaf which is suitable for
the nozzle.
An incorrectly set tape leaf lock will cause
the tape leaf to lift, resulting in part
tombstoning and parts springing off the tape.
Set the tape leaf lock securely.
Parts and dust, etc., adhering to the inside
of the tape leaf will prevent the tape from
being pressed properly. Air-blow the tape
leaf before setting a tape.
Clean away parts and dust, etc., which
have adhered to the tape leaf.
A deformed tape leaf will cause part
tombstoning and parts springing off the tape.
Replace the tape leaf if it is deformed or
if it is not flat.
Tape feed resistance increases if the tape is
not set properly in the feeder.
Set the tape correctly.
Parts which are embedded in the sprocket
and stopper can prevent tape feed.
Clean away parts which are embedded
in the sprocket and stopper.
An incorrect feed lever height will prevent a
proper tapefeed stroke, and may disable
tape feed.
1) Check the feed lever height and the
feed movement.
2) When link assembly is deformed
replace any deformed parts.
The parts reel will not rotate correctly if the
reel holder is bent.
Replace the reel holder if it is bent.

Deviation
between the
feeder and
machine pickup
position.
Check the pickup offset (X,Z) setting in
Part data.
The presence of parts or foreign matter, etc.,
on the device table or on the feeder's L-guide
can prevent the feeder from being set in the
correct position.
Parts which have adhered to the ratchet can
cause pickup position deviations at regular
intervals. Air-blow the ratchet area before
etting the tape.
Gouges in the feeder's L-guide can prevent
the feeder from being set in the correct
position.
An unsuitable reference value will result in an
automatic offset of the pickup height.
Note: Machine adjustments can be performed
only by those with a Level 3 training.
Pickup position deviations may occur after
prolonged feeder use.
Check the pickup posiiton periodically.
Lubricate the ratchet area. Failure to
lubricate can result in ratchet and stopper
wear which will cause pickup position
deviations.
• A bent nozzle will cause pickup position
deviations, and may prevent pickup from
occurring properly.
• A stuck nozzle cannot reach the part,
making pickup impossible.
• A clogged nozzle will have a lower vacuum
force, and may prevent pickup from
occurring properly.
Poor spool motion can prevent parts from
being picked up properly.
A low vacuum force may prevent parts from
being pick up properly.
Cracks in hoses can prevent parts from
being picked up properly.
Clean away parts and dust, etc., which
have adhered to the device table and
feeder tape leaf.
Clean away parts and dust, etc., which
have adhered to the ratchet.
Use a grinder to flatten the gouges in
the feeder's L-guide.
Adjust the pickup position.
Adjust the ST1 pickup height.
1) Use the nozzle check command to
check for bent nozzles.
2) Verify that the nozzle spring-back
motion is smooth.
3) Verify that the nozzle is not clogged.
If a problem is found with any of the
above, replace the nozzle.
Measure the part height sensor's nozzle
height reference value.
Ensure that the pressure value on the
vacuum pump displays at most -40kPa.
Replace the pump parts if the value fails
to reach the prescribed range.
Replace mechanical valves where the
spool motion is not smooth.
Check the connection of the hose
between the vacuum pump and the
index unit.
Check the hose between the vacuum
pump and the index unit.
Reset the ST1 feeder's feed lever.
Defective nozzle.
Vacuum force is
too low.
The ST1 feeder's
feed lever has
been tripped.
