Evaporation coating operation and the effect of vacuum coating machine

Evaporation coating operation and the effect of vacuum coating machine

Now the vacuum evaporation coating machine is vacuum technology development of more mature since a production equipment, the machinery by electrified motor to a specific place within the location of the coating material for heating. Makes the material is heated evaporation can get after, and then through the evaporation of groups of atoms, or ions cover prepared substrate, forming, and make it slowly form a thin film form. Then removed substrate that enables the film to attach to the objects need to coating surface, forming a layer of thin film, after cooling, the film is gradually formed. This is at present in the form of the evaporation coating machine main approach, is also the most commonly used vacuum coating machine for machining method.
  Due to the application of vacuum coating machine is very widely, has penetrated into vehicles, civil engineering, mechanical, packaging, environmental protection, etc., so now the vacuum coating is the main form of surface treatment. Now on the surface of the vacuum machinery for processing can realize stable appearance packaging, it's the value for the object or very large, both to ensure that an object's surface has a certain luster, can guarantee the machine for coating play a protective effect of items.

Optical coating equipment for film coating system

Optical coating equipment for film coating system

In the optical coating, it is often nothing more than a contact glass, optical aerospace industry for relatively scarce material through the optical film coating system to achieve the effect of a specific function which is the value of the film exists.
The film refractive index mainly to reduce or eliminate reflected light lenses, prisms and other optical surface, the optical element, in order toreduce light reflection loss element, in which a transparent dielectric film surface coating system, known as an anti-reflection or antireflection film, antireflection coating effect is closely related to the refractive index of the film thickness.
Transmittance and optical coating film refractive index-related, then the thickness of the film there is no relationship? In many complex optical systems, inhibition of the emitted light is very important, relatively speaking, the color of the emitted light more advanced optical system will be more and more, after the experiment, the film thickness to substantially affect light transmission is relatively small, if the thickness of the film something down, you will find the emitted light and reflected light a B exist nc * 2D optical path difference.

Analysis Principle vacuum coating equipment

                             Analysis Principle vacuum coating equipment

Principle is the principle of magnetron sputtering vacuum coating equipment , as follows:
Colliding electrons accelerated in the electric field toward the substrate during in and argon atoms, a large number of ionized argon ions and electrons, the electrons onto the substrate. Argon ions accelerated in the electric field bombardment target, a large number of target atoms sputtered, neutral target atoms deposited in a film on the substrate.
Secondary electrons accelerated toward the substrate in the process influenced by the magnetic force of the magnetic field Lorenzi, bound within plasma region near the target surface, a high plasma density region, under the effect of the secondary electrons around the magnetic field the target surface in a circular motion, the motion path of the electrons is very long, constantly in motion the process of collision ionization of argon atoms with a large amount of argon ion bombardment target, after several collisions electron energy decreases, get rid of the shackles of the magnetic field lines , away from the target, eventually deposited on the substrate.
Magnetron sputtering is bound to a magnetic field and to extend the path of movement of electrons, the electrons change the direction of motion, increase the ionization rate of the working gas and the efficient use of energy of the electron vacuum coating apparatus.
Electronic destination just substrates, the vacuum chamber wall and the target source anode is electronic home. But generally the vacuum chamber and the substrate and the anode potential in the same. Interaction between magnetic field and electric field so that a single spiral electron trajectory in three dimensions, and not only in a circular motion in the target surface. As for the type of the target surface sputtering the circumferential contour, and that the magnetic field lines are targets of the circumferential shape of circular. Distribution of magnetic field lines in different directions will film a great relationship.
Coating machine manufacturers said, not only in the interaction mechanism magnetron sputtering magnetic and electric fields of work, multi-arc plated target ion source, a plasma source and so work under this principle. The difference is that the electric field direction, voltage and current magnitude only.
