Print mode
In this field, you can set the various printing modes.
•
mode 1: printing / flooding
•
mode 2 printing - flooding - printing - flooding
•
mode 3 printing - printing
•
mode 3a printing - printing (both squeegees unpressurised in parking
position))
•
mode 4 printing
•
mode 4a printing (both squeegees unpressurised in parking position)
i
Note!
Pay attention to the following points:
1. In printing modes 1 and 2 for screen printing, one printing squeegee
(rear) and one flooding squeegee (front) are used.
2. In printing modes 3, 3a, 4 and 4a for printing, two printing squeegees
are used.
Printing pressure
Pressure at which the squeegee is applied to the stencil.
PCB thickness
Input the thickness of the PCB.
Snap off
Distance between the bottom edge of the stencil and the top edge of the
PCB in mm. „On contact“ printing, i.e. with zero snap-off, is usual for
stencil printing (the stencil lies directly on the PCB).
With screen printing, the set snap-off distance must allow the screen to
detach from the print material immediately behind the printing squeegee.
If raised, the lifting table responds immediately to changes made to the
snap-off distance.
Separation way
Distance in mm by which the table lowers at separation speed.
Separation speed
Speed in mm/s at which the stencil is separated from the PCB after the
printing process. After the printing process, the table first lowers slowly so
that the paste can fully separate from the screen.
