Notes on the correct handling of the substrates to be treated
Caution
–
Electrical voltage!

Danger from high voltage
- Never direct the plasma beam at people or animals.
- Never touch the plasma nozzle or the plasma jet when the machine is in operation.
- Never touch the workpiece to be treated or its holder during plasma generation.
- Make sure that no third party comes into contact with the workpiece to be treated
or its holder.
- If electrically conductive materials touch the workpiece to be treated, these
materials must be earthed.
Since the machine operates with high voltage, certain safety precautions must be taken.
This applies not only to direct handling of the machine, but also to the workpiece to be
treated and its holder.
In general, the workpiece holder and all other objects that the workpiece comes into
contact with must be earthed. There must be no chance whatsoever of the user or a third
party making contact with the workpiece holder (made from conductive material), for
example, during plasma treatment. It is also possible that a third party could receive an
electric shock from the workpiece through the workpiece holder.
If a holder made from insulating material is used, it must have a dielectric strength of at
least 20 kV.
A functional earth connection is provided on the machine for a special form of plasma
treatment involving transferred electric arcs. If you want to use this special application,
please contact

GmbH directly.
6.3
Carrying out surface treatment
Depending on the type and condition of your substrate, pre-cleaning before the plasma
process can improve the overall outcome.
The effect of the treatment depends on the working distance, treatment time, speed and
consistency of movement, as well as the material to be treated.
Ensure that the substrate is not thermally damaged due to movement that is too slow or
a working distance that is too close.
Treatment examples can be requested directly from
relyon plasma
GmbH.
6.4
Measures to take after the surface treatment
To achieve an optimum result, it is important that as little time as possible elapses after
the plasma treatment and that the treated surface is not touched or contaminated.
Cleaning the surface AFTER the plasma treatment is not recommended. Since the
workpiece may heat up depending on the type and duration of the plasma process, it
may be necessary to allow the workpiece to cool down first before the next process step
is executed. This is to ensure that the process will not be negatively impacted by the
introduction of heat (e.g. in certain bonding processes).
Caution
–
Hot surface!
The workpiece to be treated may be heated up by the plasma process, depending on the
process parameters. If necessary, allow the workpiece to cool down before handling it.
