When printed conductors are used both sides of a printed wiring board, electrical connection between the two sides of the board are most reliable made via plated through holes in the board. Copper is widely used as the base conductor metal in a printed circuit, it is widely used as the base conductor metal in a printed circuit, it is natural that copper also be used for plating the through holes.
Because of rigid quality and engineering requirements placed on printed wiring boards, some of the operating conditions are refined to provide optimum results. For example, many installations move the boards mechanically during plating in addition to agitation over the entire rack area. An informative through somewhat oversimplified explanation of the theoretical and practical reasons behind solution agitation for through hole plating. Preplating treatment of the board is also more critical; when pattern plating is used, a neutral or acid immersion cleaner should be used to avoid the resist breakdown resulting from use of an electrolytic cleaner.
Copper plating is widely use for many application such as on parts of battery connection and even in any appliance, this really look very interesting. But this coating usually can't stay better look for longer time, because copper can react with air and become blur color.
