Operating
To start exposure pull out the exposure drawer.
Lift the vacuum frame and click it against the magnetic
fixation.
Put your board onto the glass plate. Place the artwork onto
the board. For double sided boards, we propose that you
mount the top and bottom artwork on an L-shaped carrier
so that they superimpose and form a "bag" with lateral stops
for the board. You will have best results with the emulsion
side of the artwork (film) lying directly on the photoresist.
Take care not to enclose dust particles between the board
and the artwork.
Now slowly return the vacuum frame into its horizontal posi-
tion. (If any displacement of the artwork has occurred, re-
open the frame and rearrange the artwork.)
With the machine turned on, tip on the touch display to ac-
tivate operation.
Press the vacuum button. The button will turn green and the vacuum pump will start running. Within
a few seconds, the pump will have evacuated the air between the frame and the plate. The vacuum
indicator will show approx. 0.8 bar.
The polyester foil is structured to allow an easy and complete evacuation on the whole surface. Nev-
ertheless, there might remain an air cushion
between the artwork and the board. Wipe over
the polyester foil with your hand or with a soft
cloth to remove any rest of air. Using the
handle, smoothly close the cover.
To start the exposure, follow the instructions
below.
First activate the exposure levels you want to
use. A black square above top (on the left) or
bottom (on the right will indicate that this
exposure level is active.
Now set the time. With the slider you can set
the approximate time very fast and with the
up
and
down
buttons, you can adjust to the
precise time you want.
After everything is set and controlled, insert the drawer into the machine and press the
exposure
button. The lamps will light on and the timer(-s) will count down.
Do not switch off the vacuum during exposure! With the artwork loosing contact to the board, severe
under-cut may result.
When having completed the exposure, slide out the drawer, switch off the vacuum and open the
frame.
Never lift the frame with the vacuum pump running.
The intensity and spectre of the UV light from the LED-lamps can be compared to that of skin
tanning sets: It may irritate your eyes. You should therefore avoid to look directly into the light for a
longer time.
If for any reasons you want to stop vacuum or exposure you have to turn off machine by the main
switch.
