The Concept: each detail thoroughly considered
The nitrogen wave soldering system MWS 2300 provides
maximum flexibility and quality of soldering results.
The fluxer unit may be integrated in the machine or used as an
external module - according to the requirement.
The flexible preheat area allows to suit your specific
production requirement and leaves absolutely nothing to be
desired.
The MWS 2300 features an intelligent soldering channel
suspension. It compensates for any changes due to thermal
conditions, because the distance between solder wave and
assembly remains always the same. This is important for the
entire process and ensures perfect soldering results.
Several factors ensure a clean process area and consequent-
ly the lowest possible maintenance costs:
As a standard the MWS 2300 is equipped with filters at the
inlet and outlet of the machine, collecting the condensates in a
defined manner. Moreover, a process gas cleaning system
may be integrated. The savings which are achieved in main-
tenance costs are impressive.
A very special technical innovation of the MWS 2300 is its
integrated temperature-controlled convection cooling mod-
ule. Thus, the assemblies are cooled below liquidus before
they are leaving the machine. A clear benefit particularly at
high temperature applications, for example when using lead-
free solder alloys. Comprehensive test series and studies
have shown that an effective and quick cooling results in a
positive impact on the metallurgical structure of the solder
joints. Both, the stability as well as elasticity of solder joints is
considerably increased.
Various functions for automated process control round off the
concept and make the MWS 2300 the most innovative wave
soldering system.
Based on SEHO‘s leading nitrogen technology, the
precision and high-quality machine tooling as well as the
modular design, the nitrogen wave soldering system
MWS 2300 is a powerful piece of equipment.
Nitrogen Technology: the world leader
With its special geometric tunnel design SEHO developed a
nitrogen technology which operates - without extensive
mechanical effort - absolutely efficiently and above all with
low maintenance requirements.
Gas nozzles in the soldering area flood the system with nitro-
gen, thus displacing the oxygen in the entire process
chamber. At the inlet and unloading end of the machine the
oxygen as well as all evaporation fumes are sucked off to
achieve a stable atmosphere.
The exhaust can be monitored and controlled automatically to
ensure absolutely reproducible process conditions indepen-
dent from the production volume.
The advantage of this nitrogen technology is the low rest
oxygen value in the process area that is build-up within an
extremely short time and at minimum nitrogen consumption.
The Fluxing Area: highly precise
The MWS 2300 is equipped with an innovative fluxer area
which ensures minimum flux consumption and reduced main-
tenance.
The fluxer is driven motorically, thus providing several
advantages. Offset and spray width can individually be
programmed, travel speed and positioning are absolutely
accurate and reproducible. An automatic dosing system can
be installed to allow a defined flux application, programmable
via the software, for each particular board to be soldered.
The spray head with HVLP tecnology (high volume - low
pressure) ensures a stable spray jet and a very precise spray
pattern even at the outer edges of the printed circuit boards.
A flux quantity monitoring system ensures reliable processes
and perfect results.
This features a reproducible fluxing process with a consider-
ably reduced flux consumption. Simultaneously, mainte-
nance requirements are tremendously reduced as this
system overall features less soiling of the fluxer area.
For higher throughputs or for programmable spraying of two
different flux types, a second spray head may be installed in
the system.
The entire fluxing unit may be integrated inside the machine
or it may be installed as an external module in front of the
soldering system.
In the latter case any soiling of the process area with
condensed flux fumes is absolutely excluded. This reduces
maintenance costs additionally.
The Preheat Area: as you want it
Due to the modular design of the MWS 2300, the preheating
length from 1800 mm to 3300 mm may be individually con-
figured.
Convection preheat zones with or without the support of
radiators, convection top-side preheat zones, longwave infra-
red preheat zones or quick reacting quartz zones can be
combined in any way to perfectly suit your specific production
requirements.
A particularly high energy density and efficiency is achieved
with the pulsar preheat zones, developed by SEHO. Configu-
ring emitters individually instead of using entire segments
helps to realize shortest assembly distances.
The ideal concept for the high mix - high volume production!
The preheating area is integrated in the machine to create a
closed heat tunnel with high convection ratio. This offers
several additional advantages. For one, it ensures the abso-
lutely homogeneous heating of the printed circuit boards.
Furthermore, the machine achieves excellent energy effi-
ciency. Consequently, even high throughputs consume little
energy.
The Conveyor System: flexible and robust
The MWS 2300 features a sectional conveyor system with up
to five separate units.
Depending on the assemblies to be processed the various
conveyor sections can be set to individual transport speeds.
This is of enormous advantage because with many appli-
cations the process window will be extended considerably
due to this higher machine flexibility.
The conveyor segments may be changed quickly and easily,
without special tools.
Another fact why the machine design provides an outstand-
ing high maintenance simplicity.
Control Unit: designed for the future
The control concept of MWS 2300 is open-ended and conse-
quently a system ready for additions, such as integration of
additional sensors, heating zones or cooling modules.
Operation of the MWS 2300 is made with a PC featuring an
all-graphic Windows surface. It goes without saying that an
automatic production data acquisition for each printed circuit
board is part of the comprehensive software package. This
also applies for a remote maintenance function and many
more features.
innovative pulsar preheat concept allows cost-efficient production of large series as well as a batch size of 1
