Purpose:

Creation of plastic and soldering copper coatings with usage of original solution with specific complex of the stabilizing and modifying components for chemical deposition of copper.

Area of application:

Instrument-makingindustry, electronics and microelectronics:
  • formation of small-dimension (1-10 µm) copper foil on a substrate at continuous or selective metallization
  • deposition of thick (up to 40 µm) high plasticity soldering copper coatings
  • metallization of holes of printed circuit cards with replacing of galvanic operation
  • metallization of blind holes and holes of small and ultra small diameter, down to full imperforation of them (for example, formation of vacuum-dense conductive connection in ceramic substrates at production of SHF- micro schemes)
  • deposition of copper coatings instead of argentine coatings on functional ceramics and other substrates when other solutions do not allow to produce evenness of coatings


Advantages:

  • high stability of solution (it stands boiling without decomposing)
  • absence of a disperse phase of copper in solution, as well as phenomena of passivation of a growing surface
  • long exploitation under condition of adjusting (up to 10 metal-turns)
  • reduction of production costs
  • high diffusion property allowing to precipitate of copper up to full growing of any holes and cavities

    • Technical characteristics:

    2–7
    temperature of solution, 0C

    40–80
    plasticity (tensile strength), %

Implementation:

Enterprises: «Vityaz» (Vitebsk), «Saturn» (Kiev, Ukraine), «Elkerm» (Minsk)

Forms of cooperation:

Sale of the technology and know-how. Deposition of coatings on the small series of small-sized products of required thickness on any hydrophilic alkaliproof substrate under orders.
