Typically, a new plating bath will have about 8oz./gal of carbonate contamination. But over time carbonates build in plating baths and when carbonate concentrations reach 12 oz./ gal. a number of problems will begin to occur.
These problems include but are not limited to slower plating speeds, reduced throwing power, increased brightener consumption, grainy or burned deposits in high current density areas, plating roughness, and in extreme cases organics that begin to “oil” out or float.
Asterion offers a solution to the problem associated with carbonate build-up in alkaline plating solutions. Read More.
