There are two kinds of electroplating methods used in our common vacuum plating plants:
One is evaporation plating, and the other is vacuum sputtering. Let's take a look at the differences between the two approaches:
Vacuum evaporation is the product sprayed primer is dry is installed in the fixture on the hanging rack revolution into the vacuum furnace, and then open the inner coating machine coating machine air pumped, when reaching a certain vacuum, then the vacuum furnace of revolution tungsten wire shelf ohmic heating. When the filament temperature heat to 600 degrees when the tungsten aluminum sheet on melting evaporation gasification melting (melting temperature of different metal and common metal aluminum, nickel and copper etc. but because of the melting point, technology control and other aspects of the reason, aluminum becomes the most popular way), and then move the vacuum furnace of revolution the aluminum sheet rolling gasification frame deposited on the surface of the product, form a layer of film.
Vacuum sputtering with primary argon ion AR anti electric light hit the target appearance, the target atom is ejected and the accumulation of a thin film on a substrate surface. The properties and uniformity of the sputtered films are better than those of the evaporated films, but the plating speed is much slower than that of the evaporation. The new sputtering equipment almost all magnet electronic into a spiral motion in order to speed up the formation of argon ionization around the target, hit probability and target between adding argon ion sputtering rate, progress.
The above two kinds of vacuum plating method must be carried out under vacuum, or it will flash oxidation.
