A clean machine:
effective Residue Management
As is the case with all industrial processes,
substances are generated during SMT produc-
tion which have to be removed from the process
cycle because they contaminate the system. Our
highly effective residue management function
puries the process gas safely and reliably, and
keeps your system clean and dry.
The residue management function included in
the Vision-Series combines depending on the
system type two different modes of action: py-
rolysis in the heat zone and cold condensation in
the cooling tract’s lter units. Liquid and crystal-
line residues are effectively removed by means of
this combination.
VisonXP+, Vision XP+ Vac and Vision TripleX
are equipped with with pyrolysis in the heating
zone and and lter units in the cooling zone as
standard. Pyrolysis can optionally be added to Vi-
sionXS models for the purposes of cold trapping.
VisionXC systems are tted with cooler lter
units in their cooling zone.
In order to make your manufacturing system
even more efcient, the VisionXP+ is optionally
available with double pyrolysis. Your system’s
cleaning efciency is signicantly increased.
The rst pyrolysis unit is located underneath the
inlet area and puries the process gas from the
lower heating zones. The second pyrolysis unit
is installed on top of the inlet area and lters the
process gas from the heating zones. Cleaning
efciency is signicantly increased for the pro-
cess gas and the soldering system’s chambers
are kept clean and dry with very little maintenance
and minimal downtime.

Residues are separated with the help of a special granulate during
pyrolysis. Long molecular chains are broken down (cracked) into smaller
elements by means of thermal ssion. Temperatures from about 500 °C
are required to this end. Afterwards, the molecular chains are small
enough to be taken up by the granulate and removed from the pro-
duction process. The granulate only needs to be changed once a year,
making the pyrolysis unit easy to maintain – and you prot from minimal
downtime. Your manufacturing processes continue to run smoothly.
Pyrolysis at 500 °C
Liquid residues condense above all on the cooling
tract’s lter units, by which they are then removed.
The system is easy to clean. The lters are ex-
changed in sets at the back of the system. The
process chamber doesn’t even have to be opened.
Depending on system type, the oven is equipped
with a 2, 3 or 4-stage condensation trap.

It is important to have a high-performance cooling tract in order to guarantee optimum
soldering results and ensure that modules are cooled gently.
Rehm Thermal Systems offers a wide range of cooling tract variants for reow convection
soldering with its VisionX-Series, which can be precisely ne-tuned to suit any production
process. The water-cooled standard solution with heat exchanger and adjustable ventilation
system works as an effective "Closed Loop" system. There are several efcient, additional
options for large and high-mass boards, primarily a power cooling unit as an extended
cooling tract or a bottom cooling system.
