Functional description
Heating chamber
Thermocouples
Cooling zone
Exhaustion
The soldering ovens series 551 are full convection soldering
system of the SEF reflow family for medium serial production.
With 405 mm useable working width, an active chamber length of 850
mm
(551.10)
to 1680 mm
(551.19)
the ovens will provide a sufficient
throughput, also for bigger PCB sizes.
The soldering oven
551.10
has a heating chamber with four, the
execution
551.15
has five and the version
551.19
has eight
heating
zones. In each heating zone the temperatures for the upper convec-
tion area and the lower radiation area can be set individually.
The upper finned tubular heaters emit convection heat with the help of
hot air fans in each heating zone of the heating chamber.
At the upper heating areas the first preheating zone and the peak
zone are equipped with 3000W heating power. The other heating
zones are dimensioned with 2000 W heating power. The air tempera-
ture of each zone is controlled by means of a NiCr / Ni-K temperature
sensor on the set temperature. This thermosensor measures the
temperature of the air stream and transmits it to the controller, which
regulates the performance of the heater accordingly.
The mechanical design of the heating chamber modules provides a
directional airstream guidance and ensures a separation of the mod-
ules against each other how it is necessary for setting a soldering or
curing profile.
In the embodiment 551.10 zone 5 is designed as a cooling zone in the
upper part of the heating chamber. In the version 551.15, this zone is
used as an additional heating zone. In the version 551.15 the outlet
area of the soldering system is used as a cooling zone by using an
additional fan module with three fans. Due to the higher conveyance
speed of the soldering 551.19, the last two zones 9 and 10 are de-
signed as a cooling zone.
The upper part of the heating chamber contains also one exhaust
hood per inlet and outlet area. The heated air which is maybe contam-
inated with flux vapours will be removed through exhaust hoods at the
inlet and outlet and guided to a connected exhaust system.
The upper heating zones, exhaust hoods and cooling zone are de-
signed modular and can be exchanged easily with the help of a clip
seal. They are covered by the machine hood which can be opened
manually.
Underneath the bottom cover you will find up to eight
(551.19)
lower
heating zones, which are equipped with 1500 W heating power in the
first preheating zone and the peak zone. 1000 W heating power in the
other preheating zone are sufficient dimensioned. The radiation heat
of the lower heating zones will provide an equal heating of the PCBs
and a good soldering result, also for PCBs with a bigger heat require-
ment like multilayer boards. Therewith you can reach reflow tempera
-
tures of up to 280°C on the PCB.
