Application Industry: Surface treatment industry, such as electroplating for gold, jewellery, silver, nickel, zinc, copper, chrome etc.

Electroplating is the process of applying a thin layer of other metals or alloys on the surface of certain metals by electrolysis. It is a process of applying a metal film to the surface of metals or other materials to prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics. IGBT type rectifier is the best choice for kinds of electroplating and electrolysis, high stability, efficient and energy saving.

› Copper Plating

Purpose: Enhances adhesion for subsequent layers and corrosion resistance.

Note: Prone to oxidation (forms non-conductive copper oxide/green patina). Requires protective coatings.

› Nickel Plating

Purpose: Used as a base layer or decorative finish; improves corrosion/wear resistance. Electroless nickel offers chrome-like durability.

Note: Magnetic properties limit use in electronics (e.g., DIN/N connectors) to avoid signal interference.

› Gold Plating

Purpose: Optimizes conductive contact impedance and signal transmission.

Key: High stability but costly.

› Palladium-Nickel Plating

Purpose: Superior signal transmission and wear resistance vs. gold.

Advantage: Combines palladium’s corrosion resistance with nickel’s hardness.

› Tin-Lead Plating

Purpose: Improves solderability.

Trend: Phased out due to lead concerns; replaced by bright/matte tin alternatives.

› Silver Plating

Purpose: Best conductivity and signal performance.

Note: Conducts even when oxidized but tarnishes over time. Higher cost.

Selection Criteria

Match plating type to application needs: corrosion/wear resistance, conductivity, cost, and environmental regulations.

Elements of Electroplating:

› Cathode
The object to be plated (e.g., connector terminals or metal surfaces) where metal ions deposit into a solid coating.

› Anode

​Soluble Anode: Made of the plating metal. Dissolves during electrolysis to replenish metal ions in the solution.

​Insoluble Anode: Used for precious metals (e.g., white gold, iridium oxide). Does not dissolve but supplies electrons for reduction.

› Plating Solution
Contains ions of the target metal. Composition and concentration determine coating thickness, adhesion, and appearance.

› Plating Tank

Materials: Must resist corrosion and temperature fluctuations (e.g., polypropylene, titanium alloys).

Role: Stores solution and maintains stable plating conditions.

› Rectifier

Converts AC to DC power to drive electrolysis.

Adjust voltage/current to control deposition speed and coating thickness.

› Auxiliary Equipment

​Filters: Remove impurities from the solution.

​Heaters: Maintain solution temperature.

​Stirrers: Ensure uniform mixing.
