Mask aperture coordinate setting
When you press the [Detail] button on the [Print]-[Mask] tab, the following dialog box appears for setting the mask
aperture coordinates.
[Mask Hole] tab

This function is available only for machines equipped with an optional print inspection camera.
For more information, refer to "2.3 Using the mask scan function" in Chapter 2 of the separate option manual "Solder-
print inspection".

5. Squeegee data setting
The following parameter items can be checked and edited on the [Print]-[Squeegee] tab.

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 40 to 65 degrees. (Default setting is 55 degrees.)

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 force (pressure) 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.
K: Rolling Stroke (mm)
Specify the distance (millimeters) from the position at which the squeegee lands on the mask to the edge of the board.
Usually set to 40 to 45mm.

L: Over Stroke (mm)
Specify the distance (millimeters) from the other edge of the board to the position at which the squeegee takes off the
mask after printing solder. Usually set to 5 to 10mm.

Relation between rolling stroke and over stroke
If the rolling stroke is set vary small and the over stroke is set very large, the squeegee will land onto the solder. Set the
rolling stroke to a distance of "over-stroke + solder width + margin (+
α
)" as
shown below. If the sum of the rolling stroke
and over stroke distances exceeds 50mm, the squeegee goes away from the conveyor, and so the printing pressure may
become abnormal.
