The HotAir06 SDO ONE is a solder oven suit-
able for lead free solder processes using
S D components.
The oven is working with full convection
forced air during the preheat process. After
entering the reflow stage powerful quartz
heaters are added to speed to solder temper-
ature within a short ramp.
Once the reflow set point is reached the lamp
power will be reduced to a minimum. At this
point 85% of the heating is performed by
forced hot air heater.
This unique feature makes the oven suitable
to solder big S D components and/or com-
ponents with pads under their casing while
using lead free paste.
With good maintenance and proper use the
HotAir06 SDO ONE oven will serve your
solder needs for a long time with high quality solder results.
Some of the features include:
Outstanding reflow soldering quality for S D and hybrid
Cures S D adhesive
Two microprocessor controlled heat zones
Upon request, we can also supply bigger units and conveyorized units.

Safety Instructions
I PORTANT SAFETY RULES FORCED AIR CONVECTION OVEN
General
Please read the following instructions carefully and pay particular attention to information on operat-
ing safety and set up.
Keep these instructions at a safe place. It contains information which also refer for later mainten-
ance and cleaning.
The machines are not designed to be embedded or interconnected with other machines or systems.
They may only be used in specially equipped rooms and be operated only by qualified staff (know-
ledge in soldering recommended). Children and pets are to be kept away!
Place of in tallation
The oven is developed to install it free standing on a flat, dry surface. This surface or table must be
capable to carry a weight of at least 30 Kg. The oven should be used at normal room temperatures
(around 15 to 25 degrees. Do not install the oven in a closed cupboard or box (danger of fire). Do
not install the oven near a heating element or stove, or in a wet environment. Do not place the unit
near heat sources such as radiators, hot air ducts, furnace and the like.
Electricity
The machine is made from certified parts according to standard practice for electrical safety. This
does not relieve the user of his duty of care when handling electrically powered devices.
The main switch disconnects the machine from the power supply. We presuppose that the safety
fuses of the circuit and the residual current circuit are provided by the building's power supply (fuse
16A).
This oven must have a dedicated power outlet which may only be used by this oven.
High voltage - ONLY QUALIFIED PERSONS AY OPEN THE CASING:
Don’t put the plug and the line cord into any kind of liquid. Avoid situations that liquids or other ma-
terials entering the oven through door latching or ventilation grate.
In the case this is happening:
Switch off the oven immediately and, pull the plug from the wall ocket.
Be sure the line cord is not making a sharp hook or is hanging on sharp things. Avoid line cord to be
in contact with warm or hot surfaces. In case of damage only qualified persons may replace the line
cord.
After completion of work, the main switch should always be turned off.
Before all maintenance work on the machine (cleaning, etc.) turn off machine and pull the plug. In-
side the machine are high voltages which can be lead to death or serious injuries.
Pay attention to the warning signs on the machine. If you are not going to use the unit for some
time, remove the plug from the socket.
Ri k of fire and burning:
When the oven is in production mode it is dangerous to leave the oven unattended, high temperat -
ure and long producing times can cause to overheat the oven (risk of fire!). When you place in - or
take out – a PCB when oven is at working temperature, use protective gloves or a heat resistant

tool. We recommend the use of our PCB carrier 625 to handle the placement an removal of the
PCB.
When the oven produces too much smoke, pull the plug and close the door. This will extinct the
flames.
Do not put any flammable material near or on the reflow–oven, don’t block the ventilation
grate.
Don’t touch the cover of the oven, it can be hot. You ri k eriou burning of your kin.
Exhau t
U e the oven only in well ventilated room . Follow the safety rules of your paste supplier. During
the soldering process gas and heat may be emissioned. The gases can be affect your health.
We recommend our extraction hood and fume extractor options!
Normal u e:
The oven is developed only for soldering of PCBs , don’t use the oven for food, animals or heating
of other materials. You will lose warranty if you don’t commit to those rules.
Don’t use the oven when it’s damaged or not working properly.
Check the properly working of the oven by following the checklist below:
1. Check the door. The door must not be bent or damaged. After firing-up on the oven check
the closing mechanism by opening and closing door. The oven must respond to it. If not
DON’T USE THE OVEN but contact your dealer. Don’t use the oven when there is a piece
of material between the door latch and ceiling’s. When the door or ceilings are damaged
it’s dangerous to use the oven
2. Check the hinge and safety door handles. Don’t use the oven if they are broken or loose.
3. Check the door sealing. Are they are not damaged?
4. Check if there are no dents in the oven space
5. Check the line cord, plug and outlet. Be sure they are not damaged.
Clean the oven frequently, residues in the oven may cause fire or other dangerous situations.
Maintenance
The unit should only be maintained and repaired only by qualified personnel. Never try to do more in
the way of maintenance to your unit than the operating instructions allow. Beyond that, always con -
sult an expert for repair work.
Setup
Take over from the tran port agent
After receiving and unpacking, check the machine for possible transport damages. In case of trans-
port damage, please inform your insurance, the transport company and the manufacturer / supplier.
Place of in tallation
The oven must be standing level and there must be sufficient room to the machine for operation and
maintenance (approx 1m on all sides). When setting up the machine all safety regulations and other
local regulations are to be observed.
The oven should be installed on a good accessible table. The surface must be flat and heat resist -
ant and able to support a load of 30kg.
In ide the box you will find:

Composition
De cription of function witche :
(A) Temperature display: Depending on the
cycle, the preheat or reflow temperature is
displayed. The decimal point on the far
right shows the status of the hot air heating.
If the point lights on, heating is powered
and the temperature rises. The decimal
point one digit to the left has the same
function for the quartz heating.
(B) Time display: Depending of the cycle
you will see the actual preheat or reflow
time left. When the oven is in stand by posi-
tion, you will see the set preheat time.
(C) and (D) Status LED: Depending on the
status the LEDs show a different behaviour.
a. Both LED’s are blinking in Red and
Green. This will be the situation when the
oven is heating up or cool down and means
the oven is not ready.
b. Both LED’s are steady Green. The oven
is ready to solder with.
c. LED C is blinking and LED D is steady
Green. You have started a solder cycle and
the oven is busy with preheating. You will
see that the time bar is counting down and
shows the seconds left for reflow.
d. LED C is steady Red and LED D is blink-
ing. The reflow process is running and you
will see the quartz lamps are turned on.
Both decimal points at the temperature dis-
play will be on and temperature is rising
fast.
c. Both LED’s are steady Green. You will also hear
an acoustic signal and the temperature and time
bar shows the message “oPn dOr”. The solder
cycle is completed and you are asked to open the
drawer.
WARNING! Use protective gloves or a heat resistant tool to remove the PCB.
(E) Rocker switch to set the preheat time between 1 and 999 seconds.
(F) Rocker switch to set the preheat set point temperature between 60 and 240 °C.
(G) Rocker switch to set the reflow time between 1 and 999 seconds.
(H) Rocker switch to set the reflow set point temperature between 100 and 290 °C.
LED C and LED D are blinking in opposite colours. An error has occurred. An Error code will be
shown in the display. See at Cleaning and aintenance for more information.
(I) ain switch
(J) The reset button. Initiates a "hard reboot" of the microcontroller. The machine behaves as if the
main switch is switched off and on again. Sometimes the program will be confused by user input,
e.g. When the drawer is opened during the soldering process.

Operating
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

close the drawer (CLS DOr). After you’ve done this you will see that the temperature is rising to the
set preheating temperature. When preheat temperature is reached the oven will beep and the status
LED’s will burn steady.
Congratulations! You just finished soldering you first PCB! You now can restart the cycle from point
1.
Changing the oldering parameter .
If you are an experience operator you know that soldering is more than just heating your product un-
til the paste is melting. For the rather inexperienced users we recommend to read about soldering
as much as you can. Ask your paste supplier for advice because the paste together with the S D
components demand the solder heating curve and timing.
To create a good solder curve you have to set the temperatures and times from both the preheating
and the reflow process. This can be done with the push buttons E-F for preheating and G-H for re-
flow parameters. Editing the value during a soldering cycle isn’t possible. You can interrupt the sol-
dering process by opening the drawer. This will terminated the solder process!
The gap between preheat and reflow temperature cannot be set at less than 40°C. The min. preheat
set point value is 60 °C with and max. 240 °C. The timing reaches from 1 to 999 seconds.
For the reflow temperature this limits are between 100 °C and 290 °C. The time also reaches from 1
to 999 seconds.
Not all possible settings will give reasonable results. Your board will be either too cold or burned, if
you use extreme settings.
There is no standard setting available, because settings depend on both solder paste and compon-
ents. As mentioned before: ask your solder paste supplier about best practice.
If you are inexperienced and you will solder a PCB with lead free solder paste use these settings to
start from:
Use a solder paste with a melt point of 217 °C.
Pre-heat time: 300 sec. and Pre-temperature: 180 °C.
Reflow time: 70 sec. and Reflow temperature: 230 °C.
Remember! Tho e etting do not guarantee good re ult but a guideline!
Cleaning and Maintenance
Error code :
LED C and LED D are blinking in opposite colours. An error has occurred. An Error code will be
shown in the display. Please contact your supplier and report the error code.
Err 1 = E2Prom write error
Err 2 = Error in Reflow unit, mostly one of the lamps is broken
Err 3 = Error in Preheater unit.
Err 4 = Unone thermocouple error
Err 5 = Thermocouple connected to VCC
Err 6 = Thermocouple connected GND
Err 7 = Thermocouple not connected or broken
Changing quartz lamp
The lifetime of quartz lamps is limited. After +/- 1000 hours lamps need to be replaced. Ask your
dealer for new lamps. Changing the lamps is not problematic. Remove the two screws at the top of
the door. Now open the door and replace the lamps. (See the sketch below.)

Lubricating drawer lide
Enclosed in the package there was a small tube of XADO. This is a special heat resistant lub-
ricant. Apply it on the bars with a narrow tassel. Open and close the drawer a few times. Now
you need to "burn in" this lubricant. lt will give a lot of smoke. Therefore you need to do this
procedure in a well ventilated area. Apply a normal solder cycle several times.
Spare arts and Options
Inert ga exten ion (Optional)
ATTENTION! Provide adequate ventilation or use a protective mask. ake sure that the gas
used is non-toxic and non-explosive when heated !
Inert gas is used to prevent oxidation of the solder paste during soldering. With this extension it is
possible to use an inert gas such as NO2.
We recommend the use of NO2. If you want to use another gas, make sure that the gas used is
non-toxic and non-explosive when heated !! The use of our "suction hood" is strongly recommended
so that only a minimum of gas escapes into the room. Even when using the hood make sure there is
a good room ventilation to avoid damage to health.
Do not use more gas than the process needs!
The flow meter on the oven has a scale for air or nitrogen. If you are using other gases, then the
scale shows only a gas flow, but you can not measure exact quantities.
Due to the construction of the oven, you can not perform a 100% inert process because a little air
will always enter into the process chamber. We recommend a gas flow between 100-400 l / h at a
pressure of 2 to 4 bar use. The flow meter is limited to 500 l / h.
The inert gas is heated before it flows into the process chamber and will not disturb the temperature
profile.
