Atmospheric Plasma

Atmospheric Plasma
Atmospheric Plasma

Plasma made from atmospheric air is highly oxidative. Layers of adsorbed molecules, such as oil and water on metallic surfaces, are easily removed with this type of plasma technology. Plastics are oxidized at the surface. This type of treatment to plastics increases the wettability and adhesion of inks and glues by increasing the surface energy.

Applications

  • Adhesion promotion
  • Optical disc mastering / Photo-resist ashing
  • Medical device cleaning, activation, and coating
  • PCB desmearing and cleaning

 

PlasmaPen™

PlasmaPen™

Features & Benefits

The PlasmaPen™ is a patented atmospheric plasma system used to solve surface preparation problems. The PlasmaPen™ produces high-density plasma with a low heating effect, giving it the ability to clean and activate the surfaces including low melting point polymers. Our worldwide customer base uses the PlasmaPen™ for a broad range of applications that span the Life Science, Electronics, and Industrial markets.

The PlasmaPen™ cleans and activates the surface of materials promoting wettability of potting compounds, adhesives, inks, paints, and dyes. Surface cleaning with the PlasmaPen™ ensures reliable wire and die bonding for semiconductor packaging. It has shown particular success in adhesion promotion of anisotropic conductive film (ACF) used in flat panel display manufacturing.

The patented design of the PlasmaPen™ keeps voltages and current safely away from the plasma jet.  This means that the user is not exposed to potentially dangerous voltages and surfaces are not subjected to damaging filamentary discharges.

The PlasmaPen™ can be used manually or remotely through host automation. It is ideally suited to in situ treatments enabling rapid in-line processing, eliminating any activation lifetime issues.  Process gasses are flowed through the pen, activated and ejected through the nozzle.  PVA TePla’s design allows compressed air to be the standard treatment gas for most applications and provides for a very low cost of ownership.  Other gasses can be utilized depending on the specific application.

Features & Benefits

The RoboPen™ is an automated version of the patented atmospheric PlasmaPen™. The RoboPen™ is used to prepare surfaces by cleaning and activating materials such as polymers, glass, ceramics, metals, etc. for a broad range of applications spanning Life Science, Electronics and Industrial markets. Surface cleaning with the RoboPen™ ensures reliable wire and die bonding in semiconductor packaging, and has shown particular success in adhesion promotion of anisotropic conductive film (ACF) used in flat panel display manufacturing. The RoboPen™increases the surface energy of materials promoting wettability of potting compounds, adhesives, inks, paints and dyes.

The RoboPen™ is a self-contained, automated atmospheric plasma treatment system that can be configured and/or customized to meet a broad variety of manufacturing applications. PVA TePla works with a number of robot manufacturers in order to offer our customers a complete range of custom automation solutions. We provide any range of options starting with a basic table-top XYZ model up to the most complex multiple axis, vision recognition and high speed pick and place solution. Our product range allows customized programming and integration into any manufacturing line concept and we are able to partner with any customer preferred Robot Manufacturer.

Process gasses are flowed through the PlasmaPen™ assembly, activated and ejected through the nozzle.  PVA TePla’s design allows compressed air (CDA) to be the standard treatment gas for most applications and provides for a very low cost of ownership.  Other gasses can be utilized depending on the specific application.
