Fluxing
The fluxer of a selective soldering
machine must meet several technical
requirements: precision, speed, and above
all, reliability! It is crucial for the soldering
result that all areas to be soldered are
wetted with flux in a targeted manner.
Multidrop flux heads do not atomize the
flux but apply it in individual droplets to
predefined areas.
Preheating:
The purpose of preheating is to heat the
printed circuit board evenly before trans-
ferring it to the soldering module. Up to
50 percent of the heat energy is supplied
by infrared emitters to prevent thermal
shock when the electronic assembly
comes into contact with the liquid solder.
Soldering module:
The soldering module is at the heart of
every selective soldering system. Ersa‘s
selective soldering modules feature elec-
tromagnetic solder pumps which, thanks
to the technology used, require very little
maintenance and ensure a constant flow
rate of the solder.
This is how selective soldering systems work:
In high-volume production, simultaneous
selective soldering processes are nec-
essary in order to meet the cycle times
required. Multiwave soldering technology
enables all solder joints on an assem-
bly to be soldered in a single operation,
achieving very short soldering times of
two to three seconds. The soldering tool
is manufactured specifically for each
product. It is equipped with soldering
nozzles that are individually adapted to
the soldering joints.

Further information
For an optimal processing of electronic
assemblies, the solder pots can be posi-
tioned on either the same or on different
axes in the solder module, depending on
customer requirements. A wide range
of nozzle geometries ensures excellent
solder joint wetting, even with complex
assemblies. Dual pot systems increase
flexibility, allowing the use of different
solder alloys or nozzle geometries without
the need for changeovers.

The combinations of modules depicted
here show only some of the many varia-
tions possible with the extremely flexible
Ersa modular system. Corresponding to
the customer’s needs, throughput can be
substantially increased by implementing a
dual solder pot or dual track conveyor sys-
tem, without taking up more floor space.
On account of its modular design, the sol-
dering system can be extended: Options
or complete modules can be individually
configured and retrofitted. This saves
the investment in a new production line.
Existing floor space and production
resources used will be optimally used, and
productivity will be increased.
