How many coating methods are there for vacuum coaters?

Vacuum coating technology, simply put, is in a vacuum environment, evaporation, sputtering and other methods to emit film particles, deposited on metals, glass, ceramics, semiconductors and plastic parts and other objects to form a coating layer. Its main methods include the following:

Vacuum evaporation. The principle is that under vacuum conditions, the film material is heated with an evaporator to vaporize or sublimate, and the evaporated particle stream is directly shot to the substrate and deposited on the substrate to form a solid thin film.

Sputter coating. Sputtering coating is a high-voltage electric connection at the cathode under vacuum conditions, which excites glow discharge, and the positively charged argon ions hit the cathode target, causing it to shoot out the film particles and deposit them on the substrate to form a film layer.

Ion coating. Ion coating generally refers to a coating method that generates a large number of ions during the coating process. During the formation of the film, the substrate is always bombarded by high-energy particles, and the strength and binding force of the film are very strong.

Vacuum coil coating.

Vacuum coil coating is a technology that uses various coating methods to continuously coat the surface of flexible films in rolls to achieve some special functional and decorative properties of flexible substrates.

At present, the commonly used coating processes in the market include vacuum evaporation, sputtering, and ion plating (hollow cathode ion plating, hot cathode ion plating, arc ion plating, reactive ion ion plating, RF ion plating, DC discharge ion plating). Advanced painting processes are often used in daily life.

Vacuum coating technology is a novel new technology for material synthesis and processing, and is an important part of the field of surface engineering technology.

Vacuum coating technology is the use of physical and chemical means to coat the solid surface with a layer of special properties of coating, so that the solid surface has wear resistance, high temperature resistance, corrosion resistance, oxidation resistance, radiation protection, conductivity, magnetic conductivity, insulation and decoration and many other superior properties superior to the solid material itself, to improve product quality, extend product life, save energy and obtain significant technical and economic benefits of hail. Therefore, vacuum coating technology is known as one of the most promising and important technologies, and has shown attractive market prospects in the development of high-tech industrialization. The emerging vacuum coating technology has been applied in various fields of the national economy, such as aviation, aerospace, electronics, information, machinery, petroleum, chemical industry, environmental protection, military and other fields.

4. Install and fix the tungsten spiral heater, fix the PVDF film and aluminum cover plate on the rotating disc, put the aluminum wire in the spiral heater, and clean all parts in the bell to ensure that there are no impurities and dirt;

5. Drop the bell jar;

6. Start pumping and vacuum mechanical pump;

7. Turn on the power supply of the composite vacuum gauge;

Vacuum coating machine mainly refers to a type of coating that needs to be carried out under a higher vacuum degree, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, etc., the main idea is divided into evaporation and sputtering.

Vacuum Coating Principle:

1. Physical vapor deposition technology refers to the method of vaporizing the plating material into atoms and molecules or ionizing them into ions under vacuum conditions by using various physical methods, and directly depositing them on the surface of the matrix.

2. Chemical vapor deposition technology is a method of supplying elemental gases or compounds containing thin film elements to the matrix, and preparing metal or compound films on the substrate with the help of gas phase action or chemical reaction on the surface of the matrix, mainly including atmospheric pressure chemical vapor deposition, low pressure chemical vapor deposition and plasma chemical vapor deposition with the characteristics of both CVD and PVD.

High vacuum coating machine, coating machine is currently the most widely used equipment for making vacuum conditions. Its related components and components: mechanical pump, booster pump, oil diffusion pump, condensate pump, vacuum measurement system.

The following is a detailed introduction to the composition and working principle of each part. First, the vacuum body - the vacuum chamber according to the processing product requirements are different, the size of the vacuum chamber is not the same, the most used diameter at present, the cavity is made of stainless steel materials, the requirements are not rusty, solid, etc., each part of the vacuum chamber has a connection valve, used to connect the air pump. 2. Auxiliary pumping systemThis exhaust system adopts "diffusion pump + mechanical pump, roots pump, low temperature cold trap polycold", and the exhaust process is:

The mechanical pump first pumps the vacuum chamber to a low vacuum state that is less than about the left, which provides the premise for the subsequent vacuum pumping of the diffusion pump, and then when the diffusion pump pumps the vacuum cavity, the mechanical pump cooperates with the oil diffusion pump to form a series connection to complete the pumping action in this way. The exhaust system is an important part of the vacuum system of the coater, which is mainly composed of three parts: mechanical pump, booster pump (mainly introducing roots pump) and oil diffusion pump. Mechanical Pumps:

Also known as backing pump, mechanical pump is the most widely used low-vacuum pump, which uses oil to maintain the sealing effect and relies on mechanical methods to continuously change the volume of the suction cavity in the pump, so that the volume of gas in the pumped container continues to expand to obtain a vacuum. There are many kinds of mechanical pumps, and the commonly used ones are spool valve type (which is mainly used in large equipment), piston reciprocating type, fixed disc type and rotary vane type (this is currently the most widely used, which is mainly introduced in this article). 7
