30V 800A Electroplating Power Supply For Surface Treatment

Copper plating is a common surface treatment process used to improve the conductivity, corrosion resistance and aesthetics of metal surfaces. Copper plating is the process of coating a metallic or non-metallic surface with a layer of copper by electroplating or chemical plating. This process creates a uniform layer of copper, usually between a few microns and several hundred microns thick. There are two types of copper plating: electroplating and chemical plating. Electroplating uses an electric current to reduce copper ions from an electrolyte to the surface of the substrate, forming a copper layer. The electroplating process requires the use of a power source, a copper salt solution, and an appropriate electrolyte. Chemical plating does not rely on an electric current, but instead deposits copper on the surface of the substrate through a chemical reaction. This method allows copper plating on non-conductive materials.
Copper plating is widely used in the manufacture of circuit boards to improve electrical conductivity and solderability, on some mechanical parts to improve wear and corrosion resistance, and for decorative purposes, such as on artwork and home furnishings to add to their aesthetic appeal. Copper plating improves electrical conductivity, protects the substrate from oxidation and corrosion, and prolongs service life. There is usually good adhesion between the copper layer and the substrate to ensure the stability of the plating. During the copper plating process, parameters such as current density, temperature and pH need to be controlled to ensure the quality of the coating. After copper plating, post-treatment, such as nickel plating or coating with a protective layer, is often required to improve corrosion resistance and prevent oxidation. The copper plating process can effectively enhance the performance and appearance of the material.
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.

Types of plating

1. Copper plating: priming, enhance the ability to adhere to the plating layer, and the ability to resist corrosion. (Copper is easy to oxidation, oxidation, copper green no longer conductive, so copper-plated products must do copper protection)
2. Nickel plating: priming or appearance, to enhance the corrosion resistance and wear resistance, (where the chemical nickel for the modern process of wear resistance than chrome plating). (Note that many electronic products, such as DIN head, N head, no longer use nickel priming, mainly because nickel is magnetic, will affect the electrical properties inside the passive intermodulation)
3. Gold plating: improve the conductive contact impedance, enhance signal transmission. （Gold is the most stable, but also the most expensive.)
4. Palladium-nickel plating: improve the conductive contact impedance, enhance signal transmission, wear resistance than gold.
5. Tin-lead plating: improve soldering ability, soon to be replaced by other substitutes (because of the lead content is now mostly changed to bright tin and mist tin plating).
6. Silver plating: improve the conductive contact impedance, improve signal transmission. (Silver performance is the best, easy to oxidation, oxidation also conductive)
   
   

Elements of electroplating

1. Cathode: the plated object, referring to various connector terminals.
2. Anode: If it is soluble anode, it is the metal to be plated. If it is insoluble anode, most of them are precious metals (white gold, iridium oxide).
3. Plating solution: plating solution containing ions of the metal to be plated.
4. Plating tank: The tank that can bear and store the plating solution, generally considering strength, corrosion resistance, temperature resistance, etc.
5. Rectifier: The equipment to provide DC power supply.
