What Is Electroplating and How Does It Work?
Electroplating Example . A simple example of the electroplating process is the electroplating of copper in which the metal to be plated (copper) is used as the anode, and the electrolyte solution contains the ion of the metal to be plated (Cu 2+ in this example). Copper goes into solution at the anode as it is plated at the cathode.

process, however. Another acidic plating process based on tin fluoborate (75 to 115 g/L) and fluoboric acid (50 to 150 g/L) is designed to plate pure matte tin deposits. A major advantage of this process over the tin sulfate is that it can be operated at much higher cathode current densities, up to 100 A/dm 2 (in agitated plating solutions).
