FCVA (Filtered Cathodic Vacuum Arc)
  • The Filtered Cathodic Vacuum Arc is a technology that uses arc discharge to evaporate the material and deposit it on the surface of the product.

  • Arc discharge generates droplets of several μm-sized with ions. If this droplets are included in the thin film, the physical properties such as surface roughness are deteriorated.

  • J&L’s FCVA system is equipped with a magnetic filter to completely remove the droplets. FCVA only allows plasma ions to reach the surface of the product, and the thin film coated with this system has excellent properties such as surface roughness.


Structure and Principles of FCVA Source
  • Arc generating part (A) : Arcing on the surface of the coating material
  • Filtering part (B) : Droplet removal and a path for plasma ion passing
  • Outlet (C) : Plasma ion beam passing through the filter is deposited on the substrate
