Near Zero Defect Soldering
Where quality is paramount, manual soldering cannot
guarantee the reproducible results achievable in an auto-
mated wave soldering process. Where keeping operational
costs to a minimum, however, conventional wave solder-
ing may no longer be a viable alternative, especially in a
lead-free environment with the high costs of solder. The
tremendous operational costs associated with increased
maintenance and bath analysis, higher dross formation,
triple the costs to fill the solder pot; shorter bath life due
to copper accumulation, enormous nitrogen costs, and
higher DPM and scrap rate might cause manufacturers to
examine the possibility of switching from wave soldering to
a selective soldering process.
The VERSAFLOW selective soldering process advantages
of “Better, Faster, Cleaner & Cheaper” can translate not
only into a tremendous increase in lead free soldering
quality, but also into significant costs savings!

Basic Machine Configuration
The VERSAFLOW selective solder nozzle and pot
The revolutionary design of the ERSA VERSAFLOW
selective solder nozzle and pot offer a level of solder joint
process control never before dreamed of in a production
soldering process. All dynamic and static functions such
as solder level, wave height and solder temperature are
continually monitored & traceable. The maintenance-
free, electromagnetically operated solder delivery system
ensures a constant solder flow rate with no moving parts.
Exact wave height is precisely adjustable for repeatable
results. VERSAFLOW guarantees perfect solder joint defi-
nition and reproducibility, as well as complete documenta-
tion of individual solder parameters. All of these unique
features combine with the improved solder wave peel-off
function to offer individually programmable process param-
eters per solder joint!

Precision Fluxing Efficiency
VERSAFLOW 3 machines integrate a programmable,
precision micro drop fluxing system for selective point
or track fluxing with automatic spray accuracy control.
The flux head delivers an absolutely precise & defined
amount of flux to the smallest of areas on the PCB.
The flux pattern on the joint or PCB can be focused dots
or tracks of flux as small as 3 mm in diameter or larger!
In this way, only the precise amount of flux required is
utilized, thereby reducing flux waste and keeping ionic
contamination to an absolute minimum. For multi panel
applications, up to 4 individually synchronised working
spray heads can be installed per flux module.
Preheating Flexibility
The VERSAFLOW 3 combines three different heating
technologies from both the top & bottom-side guaran-
teeing the greatest preheat flexibility. Bottom-side short
wavelength IR, top-side, convection heating technology
as well as a new top side Hybrid heating technology
extends the process flexibility for the preheating of high
mass assemblies.
All energy efficient bottom side preheating cassettes
are segmented; depending on the specific job require-
ment, preheat configuration or total length can be var-
ied in order to ensure optimum efficiency and maximum
workflow flexibility.

Highest Efficiency In-Line Soldering via Parallel
Processing & Dual Track Option
The VERSAFLOW 3/45 has the shortest cycle time
due to the parallel processing on the individual mod-
ules. Multiple fluxing heads or solder nozzles can be
attached to the same axis system in order to double
the efficiency.
When running mixed PCBs, it is even possible to
run two different fluxes or solder alloys on one axis
system thereby deleting the downtime for flux or alloy
changes. The VERSAFLOW 3 also offers the very first
dual track capability seen in an in-line selective ma-
chine. The greatest flexibility and the highest volume
throughput can be achieved at a minimum of required
floor space. Simultaneous processing in the machine
of up to 22 PCBs is now possible. Up to six individual
solder pots and four flux spray heads can run simul-
taneously in the machine offering the highest volume
throughput in a league of it’s own. The entire transport
is segmented for frameless production and guarantees
the fastest product change.
Finally, the improved process visualization as well as
improved serviceability at the front & back side of the
machine rounds off the added value of the new design.
On & Off- Line Programming and Machine Software
The CAD Assistant software allows for simple and fast
off-line programming and thereby ensures that the ma-
chine stays running! Alternatively, you can simply scan
in the PCB and mark the relevant areas by drag and
drop programming.
The VERSASOFT machine software constantly monitors
all process related parameters on the screen and all data
can be stored in log files for traceability requirements.
The soldering process of all individual nozzles is per-
manently observed by cameras in real-time and can be
seen on the screen.
