Surface technology

The surface of a circuit, and therefore its surface technology, have a decisive impact on the function and the quality of a printed circuit board. In high-frequency technology in particular, the choice of the finishing process has a significant impact on achieving the proposed design parameters.

VARIOPRINT offers a wide range of specialised surfaces for all technological requirements. Whether special surface finishes for bonding processes or hard gold alloys for slip rings - we will always have the right solution for your requirements.

For example 

  • Galvanic Nickel Gold (Hardgold)
    Connectorgold
  • Galvanic Nickel Gold (Softgold)
    Solderable and bondable (Goldwire)
  • Electroless Nickel / Immersion Gold (ENIG)
    Solderable and bondable (Aluwire)
  • Direct immersion Gold (DIG)
    Solderable and bondable (Goldwire), therefore partiuclarly suitable for high frequency products
  • Electroless palladium / semi-autocatalytic gold (EPIG)
    Solderable and bondable (Goldwire)
    Nickel-free surface, therefore particularly suitable for high frequency products
  • Electroless nickel / palladium / gold (ENEPIG)
    Solderable and bondable (Goldwire)
  • Electroless tin
    Solderable
    Nickel-free surface, therefore particularly suitable for high frequency products
  • Immersion Silver
    Solderable
    Nickel-free surface, therefore particularly suitable for high frequency products
  • OSP (Entek Plus 106 A (X))
    Solderable
    Nickel-free surface, therefore particularly suitable for high frequency products
