According to “Fig.7.1.1 External view”, the solder supply action is executed only after printing in the
forward direction. And then, there is a possibility that print cycle time increases when the “Round”
printing is set to board data. Because the solder supply unit supplies the solder in switching the printing
direction.
The solder supply unit is attached in front of squeegee. If the supply action is executed after printing in
the backward direction, there is a possibility that a defective printing is because the solder adhered to the
squeegee may fall onto the hole of mask. So, the solder supply action is executed after printing in the
forward direction only.
7.2 PSC settings
The detailed setting items for this function are discussed in this section. Basically, you need not change
the following settings.
When this function is enabled in “3.1 Machine settings”, [Setting] – [Machine Data] – [PSC Setting] is
appeared in the tree view.

The supply mode is set by this parameter.
Please refer to "4. Details" for details.
Supply Nozzle Offset X (mm) 0.000
-999.999～
999.999
This is supply nozzle mounted offset of X direction
from squeegee center to supply nozzle. Please set an
initial value usually.
Supply Nozzle Offset Y (mm) 59.000
-999.999～
999.999
This is supply nozzle mounted offset of Y direction
from the center of the SR-axis rotation to supply
nozzle. Please set an initial value usually.
Supply Nozzle Diameter (mm) 4.000
0.000～99.999
This parameter is diameter of supply nozzle. This
parameter is used to decide the supply time.
Supply Start Timer (msec) 600
0～9999
This is the time from beginning to blow the syringe to
beginning the FX-axis movement.
Supply Finish Timer (msec) 300
0～9999
This is the time from stopping blowing the syringe to
beginning to cut the supplying solders.
FX-axis Supply Speed
(mm/sec)
100
0～999
This is the movement speed of the FX-axis in
supplying the solders.
SZ-axis Supply Pos. (mm) 0.000
-99.999～
99.999
This is the height of the SZ-axis in supplying the
solders. Please set an initial value usually.
SR-axis Supply Pos. (deg) 0.000
0.000～
180.000
This is the angle of the SR-axis in supplying the
solders. Please set an initial value usually.

Sqg. Up Pos. Rate (%) 75
0～100
This parameter is percentage of the Y direction position
of squeegee rise after the print end. This is the
parameter for keeping the rolling shape even.
NOTE:
If this is input “0”, the squeegee rises at the position
of the print end. And if this is input “100”, the
squeegee rises to the position in which only "Target
Rolling Width (mm)" was offset from the squeegee
position after the print end.
Rolling Shape Rate (%) 70
0～100
When the amount of the solder supply is calculated,
this parameter is percentage of the rolling sectional area
from true circle.
Print Stability Rolling Width
(mm)
1.000
0.000～99.999
This parameter is the control range of PSC function
about the rolling width. This is the decreasing width
from “Target Rolling Width (mm)” of board data.
Max Rolling Width (mm) 20.000
0.000～99.999
This is an input the maximum value of "Target Rolling
Width (mm)" of the board data. This parameter is
disabled.
NOTE:
If the rolling width exceeds this parameter, the
rolling solder is adhered to all aspects of the
squeegee and might not be able to be formed even
shape.
Min Rolling Width (mm) 10.000
0.000～99.999
This is an input the minimum value of "Target Rolling
Width (mm)" of the board data. This parameter is
disabled.
NOTE: If the rolling width falls bellow this
parameter, the rolling solder rises with the squeegee
