Monitoring the bath composition – Secondary components

Electroplating baths
In the surface finishing industry, organic or inorganic additives are used in electroplating baths:
  • to control the physical properties of the deposited metal layer, e.g., ductility, hardness, tear strength, brazeability,
  • to modify the visual appearance of the surface,
  • to keep large quantities of metal in solution (using complexing agents).

Essentially, the surface properties of printed circuit boards, contacts, or metal components are modified by means of acids, bases, and ions in low concentrations.

Ensuring that the desired properties are reliably achieved requires close monitoring of the bath additive concentration.
