Syringe Code (Lower) Enter a syringe code.
This code will link with the syringe code of the dispense code.

Nozzle Code Right-click this cell to select a nozzle code of the dispense nozzle data
described later.
Additionally, double-clicking this cell will jump to the dispense nozzle data.
Syringe Compress Pressure
For screw type dispense heads, set an air pressure level necessary to feed the
dispense material from the syringe to the dispense head. (Unit: MPa)
Note: If this pressure is too high, the post-drip or fluid drip may occur after
dispensing.
Additionally, if the pressure is too low, the dispense material cannot be
supplied to the screw type dispense head at adequate timing.
For pneumatic dispense heads, sets an air pressure level necessary to
discharge the dispense material. (Units: MPa)
Temperature control setting
Sets the dispense head's heater temperature. (Units: °C)
This temperature should be set higher than the room temperature.
Note: The heater and dispense head areas may be extremely hot. Use care to avoid
burn injuries.
Note: Remove the dispense material from its storage area in advance, and allow it to
reach room temperature (approximately) before using it.
Temperature tolerance
Sets the dispense head's heater temperature tolerance. (Units: °C)
Production must not occur until the heater temperature is within the tolerance
range (±).
Remaining Amount after Fluid Shortage Detection
Set an amount that can be dispensed after the fluid shortage has been
detected.
Eject time to cup after a pause
The dispense material is ejected to the cup and discharged unless it is
dispensed for a period of time set in this cell.
(Unit: Sec.)
Eject length to cup after a pause
Set a length to eject to the cup as described above.
(Unit: mm)
Eject time after a pause The dispense material is ejected to the dot station unless it is dispensed for a
period of time set in this cell.
(Unit: Sec.)

Eject dot count after a pause
Set the eject dot count for the dot station as described above.
It is recommended to perform 3 to 5 eject dots.
Note: When ejecting to cup after a pause, the dispense material may stick to the
nozzle tip.
To remove this sticking dispense material, perform the eject dots to the dot
station continuously.
Dispense diameter coefficient N
See [Dispense Amount (Hemisphere ratio)] of the dispense data described
previously.
This coefficient is determined by the dispense material.
Fluid shortage detection magnet ASSY.
The dispense head uses a magnet to detect the dispense material fluid shortage in the syringe.
Attach the magnet ASSY to the plunger inside the syringe and set it on the head.
Note: When the syringe is replaced after the fluid shortage has been detected, be careful not to dispose of the
magnet ASSY together with the syringe.
Blow the air from the syringe tip to take out the plunger and magnet ASSY.
There are two kinds of magnet ASSYs available.
Select appropriate plunger and magnet ASSY suitable for manufacturer’s syringe to be used.

This dispense nozzle data contains data related to the nozzle.
Menu: Dispense Nozzle Data
Window:
Nozzle Code Enter a nozzle code.
Right-click this cell to select a nozzle code.
This nozzle code will link with the nozzle code of the syringe data.
Comment Enter a comment.
Nozzle Type Specifies this nozzles type ("Single" or "Twin").
Right-click on the item to select the type.
Outer Diam. Enter an outer diameter of the nozzle.
(Unit: mm)
Inter Diam. Enter an internal diameter of the nozzle.
(Unit: mm)
Nozzle Pitch Enter the nozzle pitch (distance between the centers of the 2 nozzles) for twin
nozzles.
Nozzle Offset Tolerance For twin nozzles, the nozzle offset from the dot station's dispense points is
measured, and an error occurs if the deviation amount for 2 dispense points
exceeds this tolerance value.
Nozzle Tip Clearance The nozzle tip clearance corresponding to the internal diameter of the nozzle
is set automatically.
If the internal diameter of the nozzle is changed, this numeric value may also
be changed.
See [Clearance Adjust Value] of the dispense data described previously.
