PlasmaBrush PB3

High-performance atmospheric plasma system

The PlasmaBrush PB3 is our high-performance plasma system for all inline processes in industrial and high-speed applications. The PlasmaBrush PB3 is widely used in the automotive, packaging and printing sectors. The focus here is primarily on plasma cleaning and surface activation. This is primarily used to prepare the products for further downstream processes such as bonding, painting or printing.

The PlasmaBrush PB3 is a combination of a particularly compact and long-term stable plasma generator in nozzle form, a unipolar pulsed high-voltage source and a vortex flow in the nozzle. The perfectly matched components in a robust industrial design are perfect for easy integration into any system.

Although the copper nozzles originally used have very good properties in terms of burning behavior, there were customer requests to improve the oxidation resistance on the outside. This is essentially only an optical effect without any influence on the burning behavior, but it was nevertheless not possible to ensure that no oxide particles would detach from the nozzle and thus contaminate the workpiece. As a result, relyon plasma tested the copper nozzles again in a large-scale series of tests in order, among other things, to prevent the copper oxide from forming on the surface. For this purpose, very good results were achieved by nickel-plating the nozzles, which also prevents the formation of the surface oxides and the associated problems in the long term. In the tests it was shown that the coating does not lead to any impairment of the burning properties and the operating parameters. In the future, relyon plasma will therefore offer nickel-plated copper nozzles as a fully-fledged replacement for the copper nozzles offered to date.

Carbide nozzles

The most commonly used nozzles in the PlasmaBrush PB3 so far are the copper nozzles. In processes where the arc is transferred to the substrates, e.g. when cleaning or reducing metal surfaces, the copper nozzles have a very long lifetime*. When polymers are surface activated, however, the arcs dock to the lip of the nozzle, resulting in a shortened service life due to erosion.

In order to extend the lifetime of the nozzles in this popular operating mode, relyon plasma has now developed the special nozzles with a carbide core.

Due to the material properties of carbide, the carbide nozzles are much more resistant to oxidation and erosion than the standard copper nozzles. Thus, even in the treatment of polymers, a 4-fold higher nozzle lifetime could be achieved than with the copper nozzles. Due to the significantly longer service life of the nozzles, the process now requires less maintenance, is more sustainable and more stable.

Another field of application for carbide nozzles is in the semiconductor industry, where the copper abrasion of standard nozzles is often problematic. This can also be prevented by using carbide nozzles.

*At this point we expressly refrain from publishing diagrams or tables of the life expectancy of nozzles determined under laboratory conditions. These data were misleading for the consumer, because different process influences as not calculable factors strongly impair the life span.

Technology

Wide range of applications: High-performance plasma system
Wide range of applications: High-performance plasma system

Our PlasmaBrush can be adapted to fit process requirements spot-on through a wide variety of accessories. Thus, the quality of your processes and products can be optimized at minimal cost. You only use the components you really need. All components are coordinated perfectly and have been through extensive stress tests. This simplifies maintenance and servicing, and availability is ensured on the shortest possible time scale.

We have consciously adapted our high voltage power supply PS2000 to the independent industrial standard of CanOpen, which makes exceedingly reliable communication possible even under the more severe circumstances an industrial environment can bring about.

A great number of sensors or mass flow controllers operate using the same standard. Every prevalent industrial control worldwide provides a suitable interface. Up to 127 devices can be addressed via CAN node. Every PS2000 high power source can be controlled with a simple DIP switch in the address space of 0 to 99.

PS2000 High voltage source

The PS2000 High voltage source optimised for Pulsed Atmospheric Arc Technology (PAA Technology®). Due to the use of a unipolar pulsed high voltage, the arc is prevented from stabilising at “hot spots” in the nozzle. The latest IGBT switching technology and the use of high quality high voltage components ensure that the source is extremely reliable and efficient. Overloading is also not possible in continuous 24/7 operation. In the event of cable damage or short circuiting during critical operations the control unit intercepts all power fluctuations safely.

The capability of the PS2000 is particularly reflected in the fact that it can operate with variable loads and can effectively pump loads within a large potential range of up to > 12 kV. This special feature ensures continuous ignition performance across a wide power range and for different process gases. The high voltage source is switchable in a range of milliseconds at full load and therefore optimised for timed processes where highly precise timing is beneficial.

All communication is based on the reliable and fast CAN bus. Even in the event of a fault, the communication remains active. Integration into each automated production plant is simple and standardised, even in the case of several high voltage sources.

Performance features:

  • Input voltage: 220 – 240 V AC, 50-60 Hz
  • Max. input current: 6A
  • Weight: 18 kg
  • Power: 0 – 1,000 Watt (variable)
  • Open circuit voltage: up to 20 kV

FAQ

Which materials can be processed?
All Materials can be processed. Basically, all materials can be treated with the PlasmaBrush PB3. Conductive materials can be treated particularly effectively due to the transfer of the arc.
What is the temperature of the generated plasma?
The temperature distribution within the plasma flame is between 200 degrees and goes up to 1000 degrees, this differs greatly according to the particular nozzle types.
What is the optimum working distance?
For surface treatment, the optimum distance is typically between 6-25 mm.
How fast should I move the PlasmaBrush PB3 over the surface?
The optimum processing speed is very material-dependent, and can be calculated as a first approximation. Consult our application engineers.
What are the operating modes for the PlasmaBrush PB3?
For ordinary surface activation or fine cleaning to increase the wettability of a surface, the diffuse mode of operation is suitable, in which the plasma interacts with the substrate surface without any further measures. If one wants to remove an organic layer on the substrate, a so-called cathodic cleaning by means of a transferred arc is suitable. By grounding the substrate, the nozzle no longer acts as the cathode, but the substrate itself. Due to the greatly increased intensity of the treatment, thin layers of paint, for example, can be removed.
How long does the surface activation last?
The surface energy will decrease after the treatment on a timeframe of minutes to days. However the surface energy will allways remain higher than the initial value.
How can I make the activation effect visible?
In the simplest case, you will achieve good water wettability (72mN/m), which you can test with a simple water ink. Of course, there are also special test inks for a more precise analysis.
Can I overtreat a component?
Yes, you can cause thermal damage or the surface energy will decrease if the component is overtreated.
Can the PlasmaBrush clean components?
Yes, the PlasmaBrush is ideally suited for cleaning components. With suitable selection of the process parameters, oils, emulsions and release agents are removed.
Is a gas supply necessary?
Yes, operation is possible with industrial compressed air or nitrogen via a standardized Festo hose connection. The operator only has to ensure the appropriate gas flow in the range between 30-70 slm. A Festo MFM (Mass Flow Meter) can be used for this purpose, for example.
What power supply does the device require?
The PlasmaBrush can be operated via a standard household power socket.
How often should the nozzle and the electrode be exchanged?
In normal operation with air, a nozzle change is recommended every 500h. The electrode lasts approx. 1,000h.
Is the offered system ESD proof?
Yes, the A250 nozzle of our PlasmaBrush PB3 system is specifically designed for the treatment of ESD sensitive parts.
Can multiple plasma heads be used on one generator or does each head require a separate control unit?
Each PlasmaBrush PB3 system consists of the high voltage source PS2000 (compact design for integration in 19″ racks), 9 m of high voltage cable (suitable for robots and drag chains) and the plasma generator PG31 (very compact, weighing less than 1 kg).
How many different recipes/parameter settings are possible?
The PlasmaBrush PB3 allows for power as well as frequency setting at the high voltage source. Other important parameter include the choice of nozzle, the choice of process gas (CDA, nitrogen, forming gas, etc.) and the gas flow (35-80 slm).
If several recipes/parameter settings can be used: What is the concept to import, load and use different internally stored recipes?
Since the most important process parameters are speed and nozzle-susbtrate distance we determine these in close coordination with the process owner. If changes have to be made to the parameters of the high voltage source these can simply be accessed via the communication interface.
Can recipes/parameter settings be imported via MES or the SPS of the production cell?
Yes, the PlasmaBrush PB3 system can communicate via CANopen (Standard), EtherCat, Profinet, Profibus, etc.
Are different nozzles / different nozzle designs available?
Three different standard noozle designs are available: A250 for ESD sensitive substrates, A350 for temperature sensitive materials and A450 for high-speed processes. We also offer long-life versions of our standard nozzles.
What's the concept on how to exchange the nozzles?
Nozzles can be exchanged without tools by instructed personnel.
What's the range of the possible treatment area / width?
The treatment width of the PlasmaBrush PB3 system ranges between 15 and 25 mm for one pass. Larger widths can either be achieved by the use of additional plasmagenerators or by meandering which is easily possbile due to high process speed and lightweight plasma head.
What's the available power range?
The plasma jet output ranges from 480 – 770 W.
Which process parameters are controlled / monitored / tracked?
The PlasmaBrush PB3 system allows the control of power and frequency. Via the communication interface of the high voltage source PS2000 power, current and voltage of the plasma jet can be monitored in real time.
How is the PlasmaBrush PB3 controlled?
The standard communication is via CANopen. However, control via USB interface is also possible. We would be pleased to support you with the integration into your plant, e.g. with the control via Profi-Net, Profi-BUS, EtherCAT.
Which data can be sent through this interface? Which data formats are available?
The CANopen project directory is listed in the manual (see page 16-20) and includes object types (VAR, ARRAY, RECORD, etc.) and data types (VISIBLE_STRING, UNSIGNED8, etc.). The .eds-file is included in the scope of delivery.
Which process exhaust gases occur during the plasma process?
The PlasmaBrush PB3 system generates exhaust gases typical for high power jet plasma systems, like NOx and ozone. The quantities are dependent on the process gas. Detailed analysis are available.
Was the electromagnetical radiation measured for your system?
The PlasmaBrush PB3 system is CE certified and complies with all relevant regulations. Both certification and analysis are available.
How can the PlasmaBrush be mounted?
The compact and lightweight (approx. 0.5kg) plasma generator can be integrated into an existing system by means of a simple bracket. We will gladly send you the drawing files for this purpose.
What's the typical size, weight etc. of the plasma system?

Please find all relevant data in the manuals attached.
How safe is it to work with the PlasmaBrush?
Do not reach into the plasma flame during operation. The system can easily be integrated into the emergency stop circuit. The resulting emissions must be extracted, for this we recommend a volume flow of about 30m³ per hour.
Does the PlasmaBrush PB3 emit UV light?
Yes, but the UV emission using air is of low intensity and harmless at normal working distances of >200mm.
Does the PlasmaBrush PB3 emit dangerous gases?
Depending on process conditions the PB3 can emit ozone or nitroxides. We recommend to use an active filter or to exhaust the gas load into a hood.
Can the PlasmaBrush PB3 cause skin burns?
Also after swich off the nozzle can still be very hot.
