Problems solved by technology

This kind of shielding method will undoubtedly cause: (1) when removing the shielding, it will cause secondary damage to the electronic components, antenna shrapnel or circuit interface, which will affect its performance; (2) the process of shielding and de-masking is often carried out manually , can not be automated, which leads to the increase of labor costs and the extension of the coating time, which seriously affects the coating efficiency, and there may be adverse effects such as residual glue, which affects the yield of the coating process

Abstract

The invention provides a film coating method and a protective layer. The film coating method comprises the following steps: A, at least one surface of an anti-deposition layer is formed on at least one surface of a substrate without a film coating component; and B, film coating treatment is performed on the substrate by a film coating device, wherein the anti-deposition layer prevents film-formingchemical molecules in the film coating process from being deposited on the surface of the anti-deposition layer to form a film.

Description

technical field [0001] The invention relates to the field of film coating, and further relates to a film coating method and a protective layer thereof. Background technique [0002] In recent years, the rapid development of coating technology, especially the maturity of vapor deposition technology, has made the use of surface coating technology to improve the performance of electronic products a technical hotspot. Surface coating technology can endow electronic products with properties such as high drop resistance, excellent scratch resistance, good heat dissipation, water resistance, underwater electrical resistance and corrosion resistance. Plasma chemical vapor deposition technology is a commonly used coating technology at present. Plasma is generated under the action of an electric field, and the gaseous substances containing the constituent atoms of the film are chemically reacted with the help of plasma, and a protective film is deposited on the surface of the product....
