Making the dispensing stable
4.2 Setting method
Follow these steps to make setting.
1
Open the position correction dispense data screen.
Press the [Board] button and select the [Pos. Cor. Disp.] tab.
2
Create position correction dispense data.
Create the data at 4 angles (0/90/180/270) for each head used to dispense dots. Copy the coordinates
of the board data (YSD_96001_3HEAD.ygx) and enter the liquid amount and mark No. according to the
predispensing conditions. If not using predispensing, enter the dispensing liquid amount and mark
values.

To copy
1. Open board data that has already been created.
2. Open the [Board] – [Pos. Cor. Disp.] tab screen and press the [Assistant] button.
3. Move the cursor to the start row of the range you want to copy and press the [Row Selection] button.
4. Click the last row of the range you want to copy and press the [Copy] button.
5. Open the board data where you want to paste the data.
6. Open the [Board] – [Pos. Cor. Disp.] tab screen and press the [Assistant] button.
7. Move the cursor to the start row where you want to paste the data, and press the [InsPaste] button.
c
CAUTION
Create the number of data (“Dot&Check” in “Skip” column) that is more than “Minimum Sample Num” specified on
the [Machine] - “Pos Correct Dispense” screen.
3
Place a check in the “Pos Correct Pre Dispense” check box.
Before correcting the dispensing position, perform predispensing in most cases. This is possible only when
the dot station is used as the predispensing location.

5. Dot station (option)
The dot station is used as a dummy board where the dispenser head preapplies adhesive or solder paste,
in order to perform dot feedback and prevent variations in the dispensing dot size which may be caused
by a change in the liquid surface. The dot station can also be used during dispensing work to make the first
application from the head uniform after it has not been in use for a long time. A roll of special paper is used
as the dummy board, which is automatically rolled up. When the dot station is installed to the dispenser
machine prior to shipping, the default setting has already been made.
