  2. Copper electroplating - Wikipedia

    en.wikipedia.org/wiki/Copper_electroplating

    Copper electroplating is the process of electroplating a layer of copper onto the surface of a metal object. Copper is used both as a standalone coating and as an undercoat onto which other metals are subsequently plated. [ 1 ]

    en.wikipedia.org/wiki/Electroplating

    Copper electroplating machine for layering PCBs. Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.

  5. Plating - Wikipedia

    en.wikipedia.org/wiki/Plating

    Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...

  9. Electrotyping - Wikipedia

    en.wikipedia.org/wiki/Electrotyping

    Schematic apparatus for electrotyping. An electric current flows from the battery, through the copper anode, the electrolyte, and the coated mold. A copper film (the electrotype) grows onto the electrically conducting coating of the mold. Electrotyping (also galvanoplasty) is a chemical method for forming metal parts that exactly reproduce a model.
