4.8 Pre-dispense parameters
Normally, predispensing is performed to ensure that dispensing liquid is smooth and stable before starting dot
dispensing.
To reduce the paper consumption quantity, set pre-dispense parameters so that predispensing is performed at
an interval specified by number of boards or by time, instead of predispensing for each board.
Open the [Board]-[Pre Dispense] tab and check or set pre-dispense parameters as explained below.

1. Pre-dispense parameters
Set whether to perform predispensing. Select "On dot station" to perform predispensing on the dot station (option). To
change the current setting, press the [Edit] button.
2. Pattern Name
Enter the desired predispensing name.
3. Skip
Set whether to perform predispensing for each dot. Each time a "Skip" cell is clicked while the [Check Box] button is
depressed, the setting will change in the order "Execute" - "Skip" - "Check".
If "Check" is selected for the Skip parameter, check the following parameters.
• XY: The machine moves the head to the specified XY position and performs dispensed dot recognition.
• Head: Dispensing is performed by the specified head.
• Mark: Specify the mark number to use for dispensed dot recognition.

4. Qty.
Set the quantity of adhesive to be dispensed.
5. Head
Set the head No. to be used for dispense.
6. Sequence
Used to refer to a dispense sequence for which predispensing quantity, head's up/down speed etc. have been set.
If "-1" is entered, an appropriate sequence will be selected automatically according to the nozzle type and adhesive
quantity.
7. X, Y
Set the predispensing XY coordinates so that dots are not overlapped.
8. R
Set the dispense angle. "+" indicates counter-clockwise, and "-" indicates clockwise.
If "Check" is selected for the Skip parameter, this parameter will be ignored and cannot be changed.
9. Mark
If "Check" is selected for the Skip parameter, dot dispense condition is checked. Set the mark No. to be used to check the
dispensed dot.
If you are not checking dot dispense condition, set "0".
If "Check" is not selected for the Skip parameter, this parameter will be ignored and cannot be changed.
10. Feedback
Select the check box to check and correct the dispense dot size.

4.9 Dot dispense parameters
This section explains how to set dot dispense parameters required when performing dispense using the
dispense head.
Press the [Board] button, and then the [Dot Dispense] tab. The dot dispense screen will appear, so check or set
dot dispense parameters.
TIP
• When parts information and mount information are available, the dispense information can be automatically
created by using the dispense distribution (see “7.1 Dispense distribution” in this chapter).
• The teach function can also be used to enter the coordinates. For details, see “7. Checking and correcting the
dispensing positions” in Chapter 4.

1. Dot dispense parameters
Set whether to perform dot dispense.
To change the current setting, press the [Edit] button. If skip is selected, dot dispense will be skipped.
2. Pattern Name
Enter the desired dot dispense name.
3. Skip
Set whether to perform dot dispense for each component.
4. Qty
Set the quantity of dot dispensing liquid.
5. Head
Set the head No. to be used for dot dispense.
6. Sequence
Specify the desired dispense operation sequence number for which dot dispense quantity, head up/ down speeds, etc.
have been set beforehand.
If "-1" is entered, an optimal dispense operation sequence will be selected automatically according to the nozzle type
and adhesive quantity.
7. X, Y
Set the dot dispense XY coordinates so that dots are not overlapped.
8. R
Set the dispense angle. "+" indicates counter-clockwise, and "-" indicates clockwise.
