●If the measurement result Cpk is lower
than the defined value, the verification
data is reflected to the placement
position offset (dispensing).

Dispensing accuracy is
displayed
Switches a display between XY (the
dispensing position accuracy) and
dispensing area (variations in
dispensing)
Switches the display for accuracy among
pos1, pos2, and all heads.
Displays accuracy according to
dispensing angles.
Switches a target of XY (the
dispensing position accuracy).

NOTE
Checking of dispensing accuracy
Cause Troubleshooting
A different type of adhesive is applied Check the type of adhesive
A calibration nozzle is not used
Check the type of nozzle.
Calibration nozzle : No.7202
A head shaft is damaged Check for unsmooth sliding of the shaft
The illumination of a head camera is wrong Execute the lamp-value illumination calibration
Machine parameters of a dispensing head
are wrong
Execute calibration for the dispensing head
The area value of the accuracy verification
result is too large
Execute the lamp-value illumination calibration
●You can confirm the measurement accuracy result by re-measurement.
In that case, perform [Checking of dispensing accuracy] below.

Verifies the results registered as offsets in “Checking and reflection of dispensing” The procedure is the
same as the one used in “Checking and reflection of dispensing”
Though not necessarily required, this procedure will be used as a guideline for measuring the level of
accuracy of the machine.
●As for MCDATA (production program), use accuracy verification MCDATA.
(→ P.13-21-1
-10 ‘■MCDATA type’)
●Accuracy verification MCDATA is intended for accuracy verification use, so refrain from reflecting in it the
each-position-angle offsets obtained from measurement results.
(→ P.13-21-1
-1 ‘■Reflection of verification data’)
The following causes are cited as possible causes when no improvements are seen in accuracy verification
results.
