Copper Plating - an overview | ScienceDirect Topics
There are three commonly used bath types for copper electroplating: acid sulfate, pyrophosphate copper, and cyanide copper. They are all used in several areas. Acid sulfate solutions are the most common in printed circuit industry, but in other areas its corrosive nature may be preventive while pyrophosphate is used when good macrothrowing power and less corrosive solution are required ( 33 ) .

Get PriceWhat type of addition agent is used for copper plating?
Addition agents are available for leveling, brightening and "high throw" formulations that consist of lower copper content and higher sulfuric acid. A cyanide or alkaline non-cyanide copper strike is required when plating onto steel, aluminum or zinc die-castings. Another type of acid copper uses methanesulfonic acid.
What is a good copper plating solution?
For steel 1-2 oz/gal sodium hydroxide is used in the solution. Sulfuric acid copper plating solutions provide rapid deposition and less throwing power compared with cyanide copper and pyrophosphate copper solutions. Acid copper can be made to level and be very bright.
What type of cyanide is used for copper plating?
A cyanide or alkaline non-cyanide copper strike is required when plating onto steel, aluminum or zinc die-castings. Another type of acid copper uses methanesulfonic acid. These are similar to sulfuric acid copper but the acid is mild by comparison making it somewhat safer to use.
Which plating solution is best for throwing power and covering power?
Copper cyanide Plating solutions: Best for throwing power and covering power, as long as the free cyanide is not too high or too low (Range1.5-2 oz/gal). Lower free cyanide results in higher efficiency and faster plating, but less throwing power. To lower the free cyanide, add copper cyanide.
What is pyrophosphate copper plating?
Pyrophosphate copper plating solutions provide good throwing power (not as good as cyanide copper) and is used for printed circuit boards and applications where cyanide copper or acid copper should not be used. There are formulations that can be used as a copper strike, going into the solution with a cathode connection pre made and the current on.
What is acid copper used for?
Acid copper can be made to level and be very bright. Additions agents help micro throwing power such as when used for through hole plating on printed circuit boards, and for plated plastics prior to bright nickel and chrome. The solution is easy to use and maintain.
