XY-table clamp

error

(1) Verify that the XY-table is clamping panels

properly.

(2) Check the following sensors for problems

(3) - (6) (see above).

• Panel was clamped, but the clamp

sensor failed to switch on, and the

unclamp sensor failed to switch off.

• Panel was unclamped, but the

unclamp sensor failed to switch on,

and the clamp sensor failed to switch

off.

The clamping cylinder may not be

moving all the way to its motion limit

position.

Reference pin insertion sensor fails to

switch on.

Incorrect Part

data setting.

Specify the appropriate nozzle size and

cam speed settings using the Tech

Report issued by Fuji as a reference.

If accuracy deviations or missing parts

are occurring for a specific part,

decrease the XY table speed setting in

the Part data where the problem is

occurring.

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 shape 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.

Errors in the part height information or in the

table reference height Proper data

information can cause missing parts.

Fuji recommends that the actual part be

measured, with the measured value being

entered as the part height setting in Part data.

A stuck nozzle will prevent the parts from

being pushed in far enough when being

mounted, and may result in the parts being

returned.

Parts may be returned if solder, etc., is

adhering to the nozzle tip.

A misalignment between the ST9 nozzle

DOWN limit and the board height can

prevent parts from being pushed in far

enough when being placed, and may affect

placing accuracy.

Note: If a problem is found, contact your Fuji

agent.

Note: Machine adjustments can be performed

only by those with a Level 3 training.

Vacuum break problems can result in parts

being returned.

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

that melts first.

Improper ST9 cylinder operation may

prevent parts from being placed correctly.

Note: If a problem is found, contact your Fuji

agent.

(1) Press the reflective disk to verify

that the nozzle spring-back motion

is smooth.

(2) Check to see if the nozzle is clogged.

(3) Check to see if foreign matter has

adhered to the nozzle tip.

Replace the nozzle if any of the above

problems are found.

Cause Remedy Remarks Ref. Page

Check for errors in the part height

information.

Check the backup pin height, quantity,

and configuration, and check the board's

flatness.

Check to see if the XY-table is level.

Replace the cylinder unit if abnormal

noise is emitted from the cam box

uring automatic operation, or if the

nozzle DOWN limit position is incorrect.

Check for a problem with the Proper

data Z0 (0.3mm push in).

Replace mechanical valves where the

spool motion is not smooth.

Adjust the vacuum break lever position

and the speed controller.

Check the solder condition after printing.

Check the reflow temperature profile.

Nozzle length

warning

displays

Replace the nozzle where this warning

occurs, then easure the nozzle length

again.

If the measured nozzle length exceeds the

permissible value, a warning displays

onscreen.

This error occurs when dust has adhered to

the part height sensor's camera lens.

Automatic operation continues unless the

quantity of dust is such that it hinders the

measurements.

Note: Clean away the dust using cotton

swab, etc.

Error occurs because the Part data setting

differs from the height of the part which was

picked up.

Error occurs because an unsuitable part

height tolerance value is specified in Part

data. The tolerance value varies according

to the part type. Verify that the tolerance

value is appropriate for the part in question.

(Refer to the tolerance values recommended

by Fuji.)

A part may be picked up in a tombstoned

posture if the nozzle length measurement

result differs from the actual nozzle length

When using part height information, measure

the nozzle length before production begins.

A bent nozzle will cause a deviation in the

part pickup position, and may result in the

part being picked up in a tombstoned

posture.

A stuck nozzle cannot adequately reach the

part, and may result in the part being picked

up in a tombstoned posture.

A clogged nozzle will have less vacuum

force, and may result in the part being

picked up in a tombstoned posture.

A malfunctioning "acquisition timing" sensor

can cause the 7-segment display to always

show the same value, or to show the wrong

value.

Note: If sensor replacement is required,

contact your Fuji agent for assistance.

Clean the glass surface of the part

The 7-segment

display always

Cause Remedy Remarks Ref. Page

Check the height of the part where the

error occurred, and enter the correct

setting value.

Check the part height tolerance value

(%) for the part where the error ocurred,

and enter the correct setting value.

Use the nozzle check command to

perform a nozzle length measurement.

Replace the nozzle if its length is outside

the tolerance range.

(1) Use the nozzle check command to

check for a bent nozzle.

(2) Press the reflective disk with your

finger to verify that the nozzle spring-

back motion is smooth.

(3) Check for a clogged nozzle.

Replace the nozzle if any of the above

problems are found.

Turn the cam handle and check the LED

lamp status on the sensor (for

acquisition timing) inside the cam box.

If there is a problem with the sensor,

replace it.
