Output mode: Polarity reversing

Cooling method: Air cooling

Power supply type: IGBT-based

Application Industry: Plating industry, such as chrome plating

Description

Types of plating:

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)

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)

Gold plating: improve the conductive contact impedance, enhance signal transmission. (Gold is the most stable, but also the most expensive)

Palladium-nickel plating: improve the conductive contact impedance, enhance signal transmission, wear resistance than gold.

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).

Silver plating: improve the conductive contact impedance, improve signal transmission. (Silver performance is the best, easy to oxidation, oxidation also conductive)

Plated Products

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.
