GLOBAL. AHEAD. SUSTAINABLE.
Ersa Selective Soldering Systems In a Class of its Own!
Ersa selective soldering systems combine cutting-edge technology with a modular machine
layout for maximum flexibility, high throughput, and reliable process quality. Being the global
technology leader, Ersa offers a wide range of models to match your production volume,
component variety, and budget.
Maximum flexibility, highest
throughput
The VERSAFLOW series offers maximum
flexibility and the highest throughput,
with soldering machines ranging from the
established VERSAFLOW 3 and 4 to the
new VERSAFLOW ONE and VERSAFLOW
FIVE. The ECOSELECT models offer com-
pact performance and are designed as
stand-alone solutions for lean manufac-
turing concepts. Over 3,000 systems have
been installed worldwide. This emphasizes
Ersa‘s market leadership in automated
selective soldering.

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.
