Pvd coating machine is widely used in various industries, such as: optics, decoration, home furnishing, semiconductors, auto parts, parts, etc. The products plated are different, the types and models of coating equipment are different, and the coating methods are also different. Therefore, although it is in the industry of pvd coating machine, the knowledge points involved are indeed very wide. There are several coating methods, such as vacuum evaporation, sputter coating, ion coating, vacuum winding coating, etc. The following Xiaobian Huicheng Vacuum will introduce these coating methods of pvd coating machine in detail:

Vacuum evaporation
       The principle is that under vacuum conditions, the material is heated with an evaporator to vaporize or sublime, and the vaporized ion flow is directly directed to the substrate, and the solid film is deposited on the substrate.

sputter coating
       Sputtering coating is to connect 2000V high voltage to the cathode under vacuum conditions to excite glow discharge. Positively charged argon ions strike the cathode to shoot out atoms. The sputtered atoms are deposited on the substrate through an inert atmosphere to form a film layer. .

Ion coating
       That is, the vacuum ion coating that the dry screw vacuum pump manufacturer has introduced. It is developed on the basis of the above two vacuum coating technologies, so it has the process characteristics of both. Under vacuum conditions, the working gas or the evaporated material (film material) is partially ionized by gas discharge, and the evaporated material or its reactant is deposited on the surface of the substrate under ion bombardment. During the formation of the film, the substrate is always bombarded by high-energy particles and is very clean.

Vacuum roll coating
       Vacuum roll coating is a continuous coating technology on flexible substrates by means of physical vapor deposition to achieve some functional and decorative properties of flexible substrates.

      Beam deposition plating, an ion surface composite treatment technology that combines ion implantation and vapor deposition coating technology, is a technology that uses ionized particles as evaporation materials to form thin films with good characteristics at relatively low substrate temperatures. .

      Pvd coating machine coats different products, uses different coating methods, and the effect of coating is also different. When customers have coating requirements in this area, they all need to be developed by professionals in coating schemes and processes.
