Soldering your fir t PCB
We assume, the oven is set up at its final destination and connected. ake sure the door is closed.
Turn on the main switch. The oven will now start heating up to the preheat set point. To speed up
this heating process both heaters are used. Both LED’s (C-D) are blinking alternating green and red
during this stage. In the time panel you will see the preheat time. It will be stable in this stage. In the
temperature panel you can see how the temperature is rising to the preheat set point. During the
heat-up time you can edit the temperature and time settings of both zones. In that case the heat up
process is interrupted and continued after editing is finished. If the set point temperature is reached
the quartz heater will turn off. This can cause the temperature to drop. When the temperature drops
below a certain point (it depends on the height of the set point) the quartz will be activated again.
This cycle is repeated for several times until the preheat temperature is reached and established.
When the preheat temperature is reached at a stable level, the LED’s (C-D) will stop blinking, ac-
companied by an acoustic signal. The oven is now ready for soldering PCB boards with S D com-
ponents.
REMARK. When the oven is ready for use and is not used for a period of 30 minutes it will shut
down automatically. This will also happen if the drawer is opened to start a solder job and not closed
within 2 minutes. When this happens, simply push at the “Reset” button J to restart the oven. The
same cycle now is started as if you turn main switch off and on again.
Solder paste and PCB contain materials which can release gas and smoke when heated. Espe-
cially the gases and smoke from the solder paste can affect your health! Therefore arrange enough
room ventilation. We recommend the use of our “Extraction hood” combined with our fume extractor
FE-400I which is capable to suck off the gases and smoke fast enough.
When the oven is ready to solder and you’ve set all the parameters in the right manner you can start
to solder.
Open the drawer and carefully place your PCB on the middle of the rooster. This should prefer-
able be done within two minutes. If the drawer is not closed within two minutes, the oven will switch
off automatically!
WARNING! Use protective gloves or a heat resistant tool to place the PCB in position.
Close the drawer. As you can see the temperature has dropped a few degrees, that’s normal.
The pre heating cycle is started after closing the drawer. On the time display you will see the time
decreasing. The temperature display is showing the actual temperature.
When the timer is reaching zero the reflow stage is automatically started. The quartz lamps are
turned on for 100% and the temperature display shows a rapidly rising temperature. The time dis-
play is decreasing in seconds. When the reflow set point is reached you will see that the quartz
lamp are no longer at 100% power but about 15%. This means that the main part of soldering is
caused by forced hot air which makes the machine unique in its class.
When the time is reaching zero the solder cycle is ended and the oven gives an acoustic
signal. On the display the message: “oPn dOr” appears. To avoid burning of your PCB, take out the
PCB immediately! Open the drawer to maximum, so PCB and oven can cool down.
WARNING. The air coming out of the oven is VERY HOT. You can easily burn your skin seriously!
KEEP DISTANCE!
When the oven is near preheat set point you can remove your PCB from the oven and deposit it on
a heat resistant surface.
WARNING! Use protective gloves or a heat resistant tool to remove the PCB from the drawer!
The oven will cool down to a much lower temperature as the preheat set point, that’s normal. How
much depends of the preheat- and reflow-setpoints. At a certain point the oven demands that you
