1: Squeegee Type
Select "3S Head” when using the 3S squeegee head. When using an optional double squeegee, select "Double Squeegee".
TIP
The squeegee type has been set in the machine data prior to shipment according to the machine specifications. So
the same squeegee type as set in the machine data must be selected here. If not the same squeegee type, an error
is issued.
E: Solder Name
Enter the name or comment on the solder to be used. You can leave this field blank.
i: Squeeges Name
Enter the name or comment on the squeeges to be used. You can leave this field blank.
A: Squeegee Detail Type
Specify the squeegee type and size when the squeegee type is set to "3S Head” or “Double Squeegee".

B: Attack Angle (deg.)
This parameter is available only when the squeegee type is set to "3S Head". (This parameter does not appear when the
squeegee type is set to "Double Squeegee".)
Set the angle formed between the 3S squeegee scraper and the mask surface in order to print solder most efficiently. The
setting range is from 45 to 65 degrees. (Default setting is 55 degrees.)

C: One Way/Round
Select whether to print solder in one direction or in both directions.
D: F. & B. Print Condition
Select whether to use the same conditions for the forward and backward printing. When this parameter is set to "Same
Condition", the forward and backward printing operations are performed under the conditions specified for the "F.
Squeegee Speed" and "F. Squeegee Force", and the settings for the "B. Squeegee Speed" and "B. Squeegee Force" are
disabled.
E, G: F. Squeegee Speed (mm/sec), B. Squeegee Speed (mm/sec)
Set the forward and backward squeegee movement speeds to print solder. Find an optimum speed while checking the
scraped state of the solder on the mask. If this speed is too fast, the squeegee may not scrape solder properly. If too slow,
solder may spread into the backside of the mask.
F, H: F. Squeegee Force (N), B. Squeegee Force (N)
Set the pressure (force) to apply a load to the squeegee during printing in the forward and backward directions. Check
the scraped state of the solder on the mask to find an optimum squeegee pressure. Set this pressure at a lower pressure as
long as the solder is scraped properly. A larger squeegee pressure is required as the squeegee speed is set faster.
J: Solder Supply Interval (Board)
Set the number of boards to be printed per one supply of solder, based on the amounts of solder supplied and used
during printing.
I: Squeegee Pressure Check Type
This is the setting whether to check the print pressure measured while printing. If the print pressure is out of the specified
threshold while printing, the board is carried to the position where the board is taken out, then the error stops the
machine.
• Not Use
This function is not activated.
• Average
If the average value of the print pressure exceeds the threshold, the error stops the machine.
• Max / Min
If the momentary value of the print pressure exceeds the threshold, the error stops the machine.

m,n: Squeegee Pressure Uooer Range(N), Squeegee Pressure Lower Range(N)
Set the upper and lower range for the print pressure as the offset of the squeegee pressure.
Yellow parts of the line in the graph below show the period when the pressure is out of range.
Setting “0.000” deactivates monitoring the pressure.

Usually set to 40 to 45mm.
