Plastic PVD Coating Machine factory Sputtering coating is a kind of coating method in which positive ions generated by glow discharge bombard the surface of cathode target material at high speed under the action of electric field in a vacuum environment, sputtering atoms or molecules, and depositing a thin film on the surface of the substrate. The principle of sputtering is to first let the inert gas (usually Ar gas) glow discharge to generate charged Ar ions and electrons; then the electrons fly to the substrate, colliding with argon atoms continuously in the process, generating more Ar ions and electrons , the charged ions are accelerated by the electric field and hit the surface of the target material, so that the atoms of the target material are bombarded and fly out, and secondary electrons are generated at the same time, and then hit the gas atoms to form more charged particles. The target atoms carry enough energy to reach the substrate surface for deposition. The advantages of sputtering coating are: any substance can be sputtered, especially high melting point, low gas pressure element compounds; good adhesion between the film and the substrate, high coating density, less pinholes; because by controlling the discharge current and target current, The film thickness can be controlled, so the sputter coating process is easy to control and has good repeatability. Disadvantages of sputtering coating: the equipment is more complex, high-voltage equipment is required, and the price is expensive.
