1. Flow of printing condition setting
The following diagram shows the flow of the condition setting (data setting) and the setup work necessary to
perform the printing with excellent quality.
•
Before starting the condition setting, it is necessary that the basic data input and the setup work have been completed.
•
The parameter change results after completion of the condition setting may slightly vary depending on the solder and/
or mask status.
•
It is recommended to first perform the test print with the default values and gradually narrow the conditions from the
test print results.

1
Enter board size data.
Enter accurate size data (X, Y, height) of the board to be printed.
X : Sets the main stopper position.
Y : Sets the conveyor width.
Height : Sets the backup height.
2
Enter mask information.
1. Select a size of the mask to be used.
2. Select a mask standard position (standard position during the mask processing) (center or front
position).
c
CAUTION
In the YSP, you cannot use the rear position. Always select either the center or front position.
3
Select a squeegee type.
Select a type and size of the squeegee to be used. Each squeegee type has the features described
below.
Urethane squeeze : If the squeegee pressure level is too high, the squeegee is deformed, causing the
solder to be scraped away too much.
Metal squeeze : This metal squeegee is not deformed by the squeegee pressure. pressure and is less
affected by the squeegee pressure.
4
Set the backup jig.
e
1. Press the [SW. Prod. Pos.] button and check that the conveyor has moved to the setup position.
2. Press the [Conv. MS Axis Pos.] button and check that the main stopper has moved to the correct
position.
3. Press the emergency stop button and set the backup jig on the matrix plate.
