Diffuse Coplanar Surface Barrier Discharge – DSCBD – is an innovative plasma source, which has a high potential in the surface treatment of materials. DCSBD discharge has unique characteristics which differ significantly from other atmospheric plasma sources for surface treatment.

Our company provides plasma reactors using DCSBD plasma systems with flat and curved electrode for continuous, simplex or duplex surface treatment of printed materials. The devices are always tailor-made for specific customer applications and are available in a laboratory, pilot and industrial design.

Atmospheric air

DCSBD generates diffuse type of plasma in air at atmospheric pressure, but also in many other working gases without the addition of noble gas.

Power density

Extremely high power density of plasma up to 100 W/cm-3 allows short plasma exposure times and thus high speed processing.


The homogeneity of the plasma increases with increasing power density of discharge.

Electrode system

Coplanar electrode system in which generated plasma does not come into contact with metal electrodes has a virtually unlimited lifespan, it means it is no-wear electrode system. Moreover, the system is mechanically robust and machined samples can be mechanically pressed against it to achieve high-quality processing.


Contact with the human body and the plasma electrode system is not dangerous, but unless the contact occurs, it is not uncomfortable.

Industrial applications

DCSBD technology is able to operate even in dusty and moist environments, typical of industrial lines and there is a possibility of extending it for working on large surfaces. Compared to traditional industrial corona it reaches a higher economic benefit and durability of modifications without any negative effects as a “backside treatment” and “pinholing”.

The basic technical characteristics of the plasma electrode:

  • Effective surface of plasma electrodes: 200 x 80 mm
  • Depth of generated plasma: 0.3 mm
  • Operation in the atmospheric air, N2, O2, CO2, Ar, He, water vapor
  • A power: 400 W


  • Effective hydrophilicization and activation of the surface of polypropylene fabrics, polymer films, metals, glass, wood, etc.
  • Low cost and high speed surface treatment
  • Surface cleaning
  • Treatment of printed circuit boards and silicon wafers in electrical engineering
