(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

1.2.3 PCB Backup
(1) Chuck Stage Select
Select the method to fix the P.C.B. on the table chute.
The specified data is used to determine the P.C.B. fixing
method of the P.C.B. positioning stage.
Backup Jig : This specifies the method which uses
the backup jig.
Support Pin : This specifies the method which uses
the P.C.B. support pins.
Vacuum Pick-Up : Designate the vacuum pick-up mode.
The mechanism which clamps the PCB
from direction Y, is performed.
Vacuum Pick-Up : Designate the vacuum pick-up mode.
(Without Clamping) The mechanism which clamps the PCB
from direction Y, is not performed.
Select one of the options correctly according to the
settings of the mechanism section. Otherwise, the
macine will malfunction.
(2) PCB Warpage Protection
It can be selected whether or not the P.C.B. warpage protec-
tion function should be used to correct the warpage of the
P.C.B.
Select "ON" in normal cases.
When "OFF" is selected, transfer of overlapped
P.C.B.’s cannot be detected.
(3) Vacuum Release Mode
Select time when the picked P.C.B. should be released.
Before : The picked P.C.B. is released before printing opera-
tion.
After : The picked P.C.B. is released after printing opera-
tion.
Select "After" in normal cases.
When a P.C.B. has a lot of through holes and the machine
performs the printing operation with the P.C.B. being picked
up, solder paste may ooze out to the underside of the screen.
In this case, "Before" should be selected.
