• High speed selective soldering system from SEHO
that guarantees shortest cycle times less than
20 seconds.
• This „one product system“ is the ideal solution for
mass production.
• Parallel processes in the fluxing, preheating and
soldering area + parallel transfer of assemblies to the
next work station = shortest throughput times.
• High precision multiwave soldering process with
product specific multi nozzle tools.
• Nitrogen inertion of the multiwaves guarantees
highest soldering quality and minimum maintenance.
• Maximum process safety: flux quantity monitoring,
gradient-controlled preheat process, automatic wave
height control and many more.
• Simple and comfortable teach process.
• Processing of PCBs directly or in carriers.
• Two individually configurable basic versions that are
flexibly expandable.
High Speed Selective Soldering: MaxiSelective-HS
The MaxiSelective-HS represents the high speed selec-
tive soldering system from SEHO. It is the perfect solution
when highest soldering quality and shortest cycle times
are required.
Parallel processes in the fluxing, preheating and soldering
area, simultaneous contact of all solder joints with product
specific multi nozzle soldering tools as well as the parallel
transfer of the assemblies to the next work station make
this „one product machine“ the ideal system for mass
production.
Two basic machine versions of the MaxiSelective-HS that
can be equipped with four or six stations working in
parallel, offer the flexibility needed to meet your individual
production requirements. Additional buffer stations at the
inlet and outlet of the machine complete this high speed
system. In order to meet complex production challenges or
to respond to increasing manufacturing volumes, the
MaxiSelective-HS can be expanded with additional mo-
dules or it may be combined with other machine types,
also at any later date.

reliable fluxing process ensures highest product quality
Multi nozzle tools from SEHO offer unique features that
ensure maximum reliability and reproducibility of your
soldering processes:
¡
perfect peel-off due to debridging knives
¡
ideal hole fill that is achieved with permanently flowing
miniwaves and an outstanding high energy transfer rate
¡
solder ball protection
¡
quick-release fasteners for shortest maintenance times.
In addition, the solder wave height control ensures a stable
process window and guarantees highest quality even in case
of very complex assemblies.
Due to the efficient nitrogen inertion in the soldering area that
may additionally cover a continuous monitoring of the
nitrogen quality, the MaxiSelective-HS guarantees a
soldering process that requires minimum maintenance and
provides highest soldering quality.
For cooling of assemblies from top side, a cooling area may
be installed in the outlet conveyor of the MaxiSelective-HS.
100 % Process Control: Reliable Results
The MaxiSelective-HS is featured with an up-to-date control
technology. Sensors and software tools monitor and control
all process steps. SEHO‘s unique flux quantity monitoring
system monitors the actual flux quantity jetted by the nozzle
during the process, without any influence on the cycle time.
This award-winning system guarantees highest process
reliability and constant process conditions.
Monitoring systems in the preheat area make for reproducible
and gradient-controlled temperature profiles.
In the soldering area, the solder level control with automatic
wire supply as well as the automatic wave height control
ensure reliable processes with excellent soldering results.
All processes can be traced completely with the machine
communication software mcServer. mcServer systematically
collects, analyzes and prepares statistically all machine and
process parameters.
The Process Cycle: Optimum Timing
The MaxiSelective-HS is equipped with a segmented pin-
chain conveyor system allowing highest production volumes.
The printed circuit boards or carriers are reliably positioned at
the various work stations. After parallel processing of the
products at each station they are also parallely passed on to
the next work station.
Using this efficient concept, there are virtually no waiting
times and pure handling times are reduced to a minimum. As
a result the MaxiSelective-HS provides shortest cycle times of
less than 20 seconds.
The Processes: Guarantee for Highest Quality
The MaxiSelective-HS is provided with the micro drop jet
fluxing system from SEHO to ensure reliable flux deposition
to the point. With this high precision system, surrounding
areas will not be wetted and any residues on the printed circuit
boards are reduced to a minimum. Several nozzle heads and
micro drop jet nozzles can be used simultaneously to further
reduce cycle time.
The preheat area consists of multiple stations with quartz
heaters. It is designed as a closed tunnel thus realizing an
outstanding high energy efficiency.
Each emitter of the quartz heatings can be programmed
individually. This, on the one hand, includes the individual
product specific activation of each emitter, to minimize energy
consumption.
Moreover, the heating power and heating time can be pro-
grammed for each emitter individually. This ensures a repro-
ducible and very homogeneous temperature profile on the
entire assembly, even in case of very different mass.
Using a pyrometer, the preheat temperature profile can be
adjusted precisely and gradient-controlled, to correspond to
specific temperature requirements of the assemblies.
The innovative soldering area of the SEHO MaxiSelective-HS
is equipped with a soldering unit featuring product specific
multi nozzle tools. This ensures shortest cycle times.
