The development trend of vacuum coating equipment industry
With the continuous innovation and development of science and technology, high integration has become the development trend of many industries, especially the vacuum coating equipment industry. With the development of vacuum technology, the high cost performance of vacuum coating and the environmental pollution caused by traditional electroplating, vacuum coating has become the mainstream. In recent decades, due to the large demand of enterprises, my country's vacuum coating equipment has developed rapidly. With the improvement of science and technology and economy, there are more and more various types of vacuum coating equipment of various coating technologies, and the functions are more and more perfect.
Vacuum coating equipment is widely used in industrial production, whether it is small products or large products, metal products or plastic products, or ceramics, chips, circuit boards, glass and other products. Basically all products that require surface treatment and coatings need to be used. Evaporation, magnetron sputtering or ion plating are widely used in coating methods. In the control technology, more advanced computer technology and microelectronic technology are applied to make the vacuum coating equipment more efficient and intelligent.
Non-conductive (NCVM) coating equipment NCVM, also known as discontinuous coating technology or non-conductive coating technology, is a high-tech developed from ordinary vacuum coating. Vacuum plating, referred to as vm, is the abbreviation of vacuum metallization. It refers to the organic transformation of metal materials by chemical, physical and other specific means under vacuum conditions, so that the metal is converted into particles, and deposited or adsorbed on the surface of plastic materials to form a thin film, which is what we call coating. Vacuum nonconductive plating (Vacuum nonconductive plating), also known as ncvm, is the abbreviation of non-conductive vacuum metallization in English. Its processing technology is higher than ordinary vacuum electroplating, and the processing technology is much more complicated than ordinary electroplating.
Imported non-conductive (NCVM) coating equipment is used to coat non-conductive films (NCVM) on the surface of plastic electronic products: mobile phone cases, mobile phone keys, computers, digital electronic communications, etc. High-power evaporation system, thyristor control, high repeatability and stability. Unique plated-through electrode design with a time-sensitive crystal oscillator to control any film thickness. Patented workpiece rack technology, stable and adjustable speed, large output and high yield.
NCVM utilizes films such as metallization, depletion compounds, etc., and utilizes discontinuous properties to obtain a final appearance with a metallic feel without affecting wireless communication transmission. First of all, it is necessary to achieve non-conduction to meet the normal use of wireless communication products; secondly, to ensure the important appearance requirement of "metallic texture"; finally, through the combination of UV coating and coating, the physical properties and weather resistance of the product are finally guaranteed satisfy customer needs. NCVM can be applied to various plastic materials, such as PC, PC+ABS ABS. PMMA, nylon, engineering plastics, etc. It is more in line with the green environmental protection requirements of the manufacturing process. Alternative technology for non-chrome products is suitable for all plastic products that require surface treatment, especially 3C products with signal transceivers, especially around radomes, such as mobile phones, PDAs, smartphones, etc.
The non-conductive film coating equipment manufactured by American Mustang Vacuum Co., Ltd. has emerged in an endless stream of new technologies, new products and new processes. Its product value is high, the market potential is large, and the profit margin is large. It will gradually replace the traditional electroplating industry and become the mainstream technology for surface treatment of plastic products, bringing obvious economic and social benefits to enterprises and society. Operation and maintenance of evaporation equipment.
The working method of the evaporation equipment is to place the material to be plated and the substrate to be plated in a vacuum chamber, heat the material to be plated by a certain method, evaporate and sublime it, and sputter to the surface of the substrate to form a thin film. Forming the film under vacuum conditions can reduce the collision of the atoms and molecules of the evaporated material in the process of flying to the substrate, reduce the chemical reaction (such as oxidation) between the active molecules in the gas and the evaporation source material, and reduce the gas molecules entering the film. amount of impurities. Generally, vacuum evaporation requires the pressure in the film-forming chamber to be equal to or lower than 10-2Pa. When the evaporation source is far away from the substrate and the film quality is higher, the pressure is lower.
