Advantages of Plasma

Surface Interaction

  • Plasma treatment only affects the near surface of a material; it does not change bulk material properties
  • Plasma cleaning leaves no organic residue, unlike many wet cleaning processes; under proper conditions, it can achieve complete contamination removal, resulting in an "atomically clean" surface
  • Plasma has no surface tension constraints, unlike aqueous cleaning solutions; it can clean rough, porous or uneven surfaces
  • Plasma treatment occurs at near-ambient temperature, minimizing the risk of damage to heat-sensitive materials

Process Flexibility & Consistency

  • Depending on process gases and usage configuration, plasma treatment can be used for cleaning, activation, sterilization and general alteration of surface characteristics
  • Plasma will react with a wide variety of materials; as such, plasma can also treat assemblies made of different materials
  • Plasma cleaning can treat three-dimensional parts with complex geometries

Low Cost / Ease of Use

  • Plasma processing is highly efficient, with short processing times, no drying stage and little energy consumed
  • Plasma treatment helps to avoid process yield loss due to heat or solvent damage
  • Plasma processing is easier to use and maintain than chemical or mechanical processes; in addition, it requires no complicated chemical analysis or maintenance
  • Plasma treatment frequently eliminates the need for solvents, along with their ongoing purchase and disposal costs

User & Environmental Safety

  • Plasma treatment eliminates safety risks associated with worker exposure to dangerous chemicals
  • Plasma processing is contained within a vacuum chamber, with little or no direct worker exposure
  • Plasma processing operates at near-ambient temperatures with no risk of heat exposure
