Vacuum coating technology, simply put, uses evaporation, sputtering, and other methods to emit coating particles, depositing them on objects such as metal, glass, ceramic, semiconductor, and plastic parts to form a coating. PVD coating machine The main methods include the following:
PVD coating machine vacuum evaporation
The principle is that under vacuum conditions, the thin film material is heated by an evaporator to vaporize or sublime it, and the evaporated particle stream directly goes to the substrate, and the solid thin film is deposited on the substrate.
PVD coating machine sputtering coating
Sputtering coating is a process where, under vacuum conditions, a high voltage is applied to the cathode to excite glow discharge. Positively charged argon ions bombard the cathode target, causing it to eject thin film particles, which are deposited on the substrate to form a film layer.
PVD coating machine ion plating method
Ion plating usually refers to a plating method that generates a large number of ions during the plating process. During the film formation process of the PVD coating machine, the substrate is continuously bombarded by high-energy particles, resulting in high film strength and adhesion.
Vacuum winding coating
Vacuum coating is a technology that performs continuous coating on the surface of rolled flexible films through various coating methods to achieve certain special functions and decorative properties of the flexible substrate.
In order for optical components to meet the optical, electrical, and physical properties required in optoelectronic instruments and components, one, multiple, or even hundreds of layers of film can be coated on their surface. Such as anti-reflection films, reflection films, dichroic films, filter films, electrothermal films, protective films, polarizing films, etc. The coatings of optical components are mainly divided into physical coatings and chemical coatings. With the development of vacuum technology and thin film monitoring technology, it is easy to obtain thin films with stable performance and complex structures. Therefore, vacuum coating is the main method in production.
Classified by thin film performance, common film layers include: anti-reflection films, reflection films, dichroic films, filter films, electrothermal films, conductive films, protective films, etc.
According to the structure of the film, it can be divided into single-layer film, double-layer film, and multilayer film.
The above is PVD coating machine information introduction, hope it helps!
