(4) Print Area

Set parameters as offset values of the P.C.B. end plane in the

Y direction.

Unit : mm

Enter the offset values based on the pattern program

coodinates of the end planes on the origin and rear sides.

When the defaults "0" (zero) are set, the whole area of the

P.C.B. is printed.

Various offsets are considered in the actual printing range as

shown below.

1.2.2 Print Data

(1) Screen Basis

Select a reference type of the screen frame.

Center Ref. : The center of the screen frame is regarded as a

reference point.

Front Ref. : The front side of the screen frame is regarded

as a reference point.

Rear Ref. : The rear side of the screen frame is regarded

as a reference point.

(2) Round-Way Printing

It can be selected whether or not the round-way printing opera-

tion should be performed.

ON : The machine performs the round-way printing opera-

tion.

OFF : The machine does not perform the round-way printing

operation.

(3) Frame Select

Select dimensions of the screen frame to be used.

(4) Prntg. Press.

Set the printing pressures of the front and rear squeegees.

Unit : N

Data Input Range : 9 to 200

If the same solder paste is used for a long time, vis-

cosity might increase, causing printing error. To pre-

vent that, we recommend setting the printing pressure

as high as possible, enabling printing without hin-

drance.

(5) Squeegee Select

(6) Squeegee Spd.

Select the speed at which the squeegees move back and forth

for printing.

Unit : mm/s

For. : Set the speed at which the squeegees move forward

(from the rear to the front side).

Back. : Set the speed at which the squeegees move back-

ward (from the front to the rear side).

(7) Screen Distance

Set the clearance between the screen and the upper surface

of the P.C.B. during printing operation.

Unit : mm

Data Input Range : -1.5 to 3.0

(8) Separation Mode

Set a parameter to determine whether or not the squeegees

must move up after the P.C.B. has descended or the P.C.B.

must move down after the squeegees have ascended when

the screen frame is separated from the P.C.B. after the

completion of printing.

Select "PCB Down" in normal cases.

PCB Down : The squeegees move up after the P.C.B. has

descended.

Squeegee Up : The P.C.B. moves down after the squeegees

have ascended.

(9) Separation Speed

Set the speed at which the screen frame should be separated

from the P.C.B. after the end of printing.

Unit : mm/s

Data Input Range : 0.05 to 3.00

(10) Separation Acc.

Set the acceleration rate at which the screen frame should be

separated from the P.C.B. after the end of printing.

Unit : mm/s

Data Input Range : 0.1 to 50.0
