High-efficiency vacuum drum double-sided sputtering and electron beam evaporation combined system: revolutionary coating technology

Technical principle of vacuum coating machine
Vacuum coating machine is a device that coats materials under high vacuum conditions. It uses evaporation, sputtering, electron beam evaporation and other principles to evaporate or sputter the coating material in the form of atoms or molecules onto the surface of the substrate to form a uniform and stable film. These coatings can form a protective film on the surface of various materials to improve their physical and chemical properties, such as improving corrosion resistance, friction resistance and electrical conductivity.
Vacuum coating technology can be roughly divided into two main methods: evaporation coating and sputtering coating. Evaporation coating is to evaporate and deposit on the surface of the substrate by heating the target material to form a thin film; while sputtering coating is to bombard the target material with high-energy particles, so that the surface atoms or ions are sputtered onto the substrate, and finally a thin film is formed after a series of processes. These two methods have their own characteristics and are suitable for different application requirements.

Advantages and applications of double-sided coating technology
Among these coating technologies, Vacuum Roll to Roll Double-sided Sputtering & E/B Evaporation combined system is a revolutionary technology that combines sputtering coating and electron beam evaporation coating, which can ensure high efficiency while ensuring high precision and stability of coating quality.
The working principle of this system is based on double-sided coating technology, that is, sputtering and evaporation of two targets at the same time to evenly coat the material on both sides of the substrate. The application of this double-sided coating technology enables the system to complete more coating tasks in the same production cycle, greatly improving production efficiency and providing customers with more diverse coating options.
The system combines the advantages of electron beam evaporation and sputtering technology to provide different coating solutions for different materials. For example, in the coating process of metal materials such as copper and aluminum, electron beam evaporation can provide a higher material deposition rate to ensure uniform and compact coating thickness, while sputtering technology can help form a stronger film and increase the adhesion and wear resistance of the film.
The biggest advantage of double-sided coating technology is that it can coat both sides of the substrate at the same time, which makes it far superior to traditional single-sided coating technology in production efficiency. Whether in electronic components, optical devices, or in high-precision fields such as automobiles and aerospace, double-sided coating technology can greatly improve work efficiency and reduce costs.
In the electronics industry, copper and aluminum alloys are common substrates, and double-sided coating is often required to improve their corrosion resistance, conductivity and other electrical properties. Through the vacuum drum double-sided sputtering and electron beam evaporation combined system, metal materials can be quickly and evenly coated on both sides of the substrate, significantly improving the quality and reliability of the product.
In the field of optics, optical coatings on the surface of the substrate are crucial to improving specular reflection, anti-reflection, light transmittance and other properties. Double-sided coating can effectively improve the performance of optical components, especially in the production of high-precision optical lenses and displays, it can provide higher quality surface coatings and improve the overall performance of the product.
In the field of metal coatings, copper and aluminum are two common substrates, which are widely used in electronics, automobiles, aerospace and other industries. However, copper and aluminum often face many challenges in surface treatment, such as insufficient adhesion of the material surface, easy detachment of the coating, or uneven coating. Through the vacuum drum double-sided sputtering and electron beam evaporation combined system, these problems can be effectively solved.
For metal materials such as copper and aluminum, the combined use of evaporation and sputtering technology can ensure the uniformity and stability of the coating and improve the adhesion of the film. By optimizing the process parameters of electron beam evaporation and sputtering, a more compact, uniform and durable film can be obtained while ensuring high production efficiency, meeting the needs of modern industrial fields for high-performance materials.
In the process of using vacuum coating machines, regular maintenance and care are essential to ensure that the equipment is always in an efficient operating state. First, the target material and vacuum chamber inside the equipment should be cleaned regularly to avoid deposition and contamination of coating materials. Secondly, the working status of the electron beam evaporation and sputtering system should be checked to ensure that the temperature control, pressure control and other functions of the equipment are normal. In addition, regular inspection of the equipment's sealing, cooling system and high-temperature components is also the key to maintaining long-term stable operation of the equipment.
