In a 150a 15v low ripple plating rectifier from Chinese manufacturers, AC input is first rectified into pulsating DC, then filtered to obtain stable low-voltage DC power. The “variable frequency conversion” stage inverts this high-voltage direct current into approximately 30kHz high-frequency alternating current. This high-frequency AC is then transformed into secondary voltage via a high-frequency transformer and filtered through a high-frequency rectifier circuit to produce the required output voltage. The ​Electroplating Rectifier Power Supply employs a control circuit to sample output voltage and current. These sampled signals undergo closed-loop feedback to generate pulse width modulation (PWM) signals, which regulate the inverter circuit and maintain stable output voltage/current – a critical requirement for precision electroplating applications.

Manufacturers widely use electroplating rectifier equipment for various surface treatment applications, including PCB electroplating, hard chrome coating, copper plating, nickel plating, zinc plating, gold plating, tin plating, and silver plating, among other metal finishing.

Role of electroplating:

Electroplating addresses core industrial challenges through tailored surface engineering:

Corrosion mitigation – Zinc deposition on steel fasteners creates sacrificial anodic protection in marine environments, delaying structural failure.

Abrasion management – Hydraulic cylinder rods utilize hard chromium deposits (≥800 HV) to withstand particulate wear in mining equipment.

Surface aesthetics – Luxury watch cases employ 5μm gold plating over nickel undercoats for corrosion-resistant luster.

Electrical performance – High-frequency PCB vias rely on electroless copper for uniform conductivity in multilayer boards.

Joining reliability – Automotive ECU connectors use matte tin finishes to maintain solder joint integrity after thermal cycling.

Asset preservation – Worn turbine shafts are rebuilt with engineered nickel-cobalt deposits, restoring OEM tolerances.

Extreme environment adaptation – Jet engine combustor liners incorporate diffusion-modified nickel aluminide coatings for oxidation resistance at 900°C+.

Types of electroplating:

› Copper Plating

Primarily applied to improve substrate adhesion for subsequent plating layers while enhancing corrosion resistance. Requires protective topcoats due to oxidation concerns—unprotected copper forms non-conductive patina over time.

› Nickel Plating

Serves as a functional base layer or decorative finish, offering excellent corrosion and wear resistance. Electroless nickel variants approach chrome-level durability. Note: Magnetic properties restrict usage in sensitive electronic components (e.g., RF connectors) where signal interference must be avoided.

› Gold Plating

Preferred for critical electrical contacts where stable impedance and optimal signal transmission are essential. Though highly reliable, material costs limit large-scale applications.

› Palladium-Nickel Plating

Superior wear resistance and signal stability vs. gold plating.

Combines palladium’s oxidation resistance with nickel’s structural integrity for high-cycle connectors.

› Tin-Lead Plating

Historically favored for solderability enhancement. Now largely discontinued due to RoHS regulations; modern replacements include pure matte or bright tin formulations.

› Silver Plating

Delivers maximum electrical conductivity and signal performance across high-frequency applications. Maintains functionality when oxidized but requires anti-tarnish treatments due to surface darkening. Premium cost reflects performance advantages.

› Selection Considerations

Specify plating type according to:

Required corrosion/wear resistance thresholds

Electrical performance parameters

Budgetary constraints

Environmental compliance requirements

Long-term maintenance considerations

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.
