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

VisionX-Series combines depending on the sys-

tem type two different modes of action: pyrolysis

in the heat zone and cold condensation in the

cooling tract’s lter units. Liquid and crystalline

residues are effectively removed by means of this

combination.

VisonXP+ and Vision XP+ Vac are equipped with

pyrolysis and lter units in the cooling zone as

standard. Pyrolysis can optionally be added to

VisionXS models for the purposes of cold trap-

ping. 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. It puries the nitrogen from the 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 process 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 produc-

tion process. The granulate only needs to be changed once a year, mak-

ing 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.

VisionX-Series | Residue Management

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 reflow 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 op-

tions for large and high-mass boards, primarily a power cooling unit as an extended cooling

tract or a bottom cooling system.
