Spacers between permanent magnet units in (magnetron sputtering coating machine) magnetron sputtering target

In the magnetron sputtering target, gaskets should be installed between the permanent magnet units. The gasket should be made of materials with good magnetic permeability, such as pure iron, low carbon steel and other materials. Regarding the specification and size of the gasket, its diameter is usually about 5mm larger than the diameter of the permanent magnet, and the thickness is 3mm-5mm. Such size specifications can use magnetization to form a more ideal magnetic field on the target surface, expand the target's affected area and increase the overall rate of sputtering coating.

The market scale of the vacuum coating machine industry in 2020 is based on a large number of first-hand surveys and data monitoring covering major industries (including the output and output value of the target product or industry within a specified time, etc., according to the population, people’s needs, age distribution, and region We provide customers with reliable market and segmented market scale data and trend judgments through self-developed multiple market scale and development prospect estimation models, and assist customers in judging the target market size and development Prospects to provide reliable and continuous data support for market development and market share estimation.

　　 The market scale is not only the market sales of vacuum coating machine products within a certain range, but also the scale of users or sales. We estimate the current market based on the area where the vacuum coating machine is concentrated, the stage of development, and the number of users; secondly, we estimate the future market based on the potential users and development trends of the vacuum coating machine. Finally, the overall scale of the vacuum coating machine product market can be known.

　　In the calculation of the vacuum coating machine market size, we mainly adopt the following methods

　　 One, source inference algorithm

　　 traces the market scale of this industry back to the source industry that gave birth to this industry, and derives the data of the vacuum coating machine industry through the interpretation of the source industry data.

　　 Second, strong correlation data inference algorithm

　　 The so-called strong correlation can be understood as a strong relationship between the sales of products in the two industries. Through the analysis of the strongly related industries in the vacuum coating machine industry, the accuracy of the market scale data is confirmed.

　　 Three, demand estimation algorithm

　　 is to measure the scale of the target market based on the needs of the target customers of the vacuum coating machine products.

　　 Fourth, sampling analysis method

　　 is to draw a certain sample from the population by sampling, and then infer the overall situation based on the sample. Sampling methods mainly include: random sampling, stratified sampling, overall sampling, systematic sampling and snowball sampling.

　　 Five, typical reverse deduction method

　　Based on the research team's research on the sales and market share of individual brands (especially leading brands), the scale of the entire industry is reversed.
