Barrel plating for electrical components (e.g. ceramic capacitors) used to grow terminals. Barrel plating is a form of electroplating used for plating a large number of smaller metal objects in one sitting. It consists of a non-conductive barrel-shaped cage in which the objects are placed before being subjected to the chemical bath in which they become plated.

The Al 2 Cl 7 − anion plays a crucial role in achieving the stripping/plating of aluminum. Firstly, due to its asymmetrical structure, the Al 2 Cl 7 − anion with a high electrochemical activity can act as a reactant in the aluminum plating reaction. Additionally, it can eliminate the non-conductive oxide film on aluminum and augment its ...
connection to the capacitor. Metal powder is mixed with solvents and glass frit to create the termination ink. Each terminal of the capacitor is then dipped in the ink and the parts are fired in kilns. Plating: Using an electroplating process, the termination is plated with a layer of nickel and then a layer of tin.
