EMLS 2030 - Inertec

The INERTEC development team has compiled a catalogue of requirements, resulting from the exchange of experience with customers who have already
been working for years in the area of selective soldering: this is divided into two thematic groups.
The inert gas consumption is considerably lower than that of inert gas coil soldering systems.
The soldering system is based on the patented technology of the active, wettable die which enters into the inert gas flow to transfer solder to the soldering
points of the entire component group in one cycle subject to geometric limitation. The occurrence of droplets of solder caused by the technical process
itself is considerable reduced. Gaseous activators are not necessary.
THE INERTEC TECHNOLOGY
EMLS 2030
INERTEC has developed a multiple inert gas mass
production soldering system to compensate for this
disadvantage. The system can achieve timing
intervals which are comparable to the known coil
soldering machines.
However, the known selective soldering processes
with only one inert gas miniature soldering coil have
disadvantages as far as the timing interval is
concerned since a sequential soldering process
takes place. This means that each soldering point
has to be individually processed.
This technology has enabled many users to change
over from conventional coil / reflow soldering
assembly to a more modern 2 X reflow soldering
assembly with subsequent selective soldering
without abstaining from complex electronic
components with high component density.
INERTEC has reacted in good time to the apparent
changes in assembly strategies in the electronics
industry caused by the introduction of SMD
technology by establishing the first selective
soldering systems in assembly plants all over the
world, even in 1992.

7. The soldering system is ideally prepared
for lead-free alloys because of testing
which has already bee done at
temperatures in the range of > 350° C.
The patented soldering module contains
450 kg of solder. This is standard for
mass production soldering systems and
ensures a stable process sequence
when working in three shifts.

production starts up
Technical data EMLS 2030
The body of the machine consists of a
solid, welded tubular steel frame with
location points for the individual modules.
4. CIM is now possible from a technical
point of view.
The soldering system is equipped with
the classical components of a mass
production soldering machine, such as a
flux system and a high performance
preheater.
3. Creation of a soldering tool library.
2. Predictable behaviour of the solder in the
individual soldering tools.
The soldering system has already been
tried and tested many times in assembly
and is designed for inline-operations:
masks can also be processed however:
these automatically ensure a higher
through put for smaller individual
component groups.
