Notebook computer shell vacuum sputtering method

Abstract

The invention provides a notebook computer shell vacuum sputtering method, which comprises the following steps of clamping a notebook computer shell to fix the position of the notebook computer shell by a clamp; carrying out corresponding polishing and degreasing treatment on the fixed notebook computer shell; performing automatic dust removal and static electricity removal on the degreased notebook computer shell through a negative ion dust removal gun and dust removal gauze; carrying out sand blasting treatment on the surface of the plastic shell base material through emery for the shell subjected to dust removal treatment in the previous step; cleaning the surface of the plastic shell base material subjected to sand blasting treatment through ultrasonic waves; performing vacuum coating on the the notebook computer shell, wherein the surface of the shell is coated with a layer of copper film, the surface of the shell is coated with a layer of silver film, and then the surface of the shell is coated with a layer of copper film, so that a'copper-silver-copper 'sandwich type coating structure is formed; and spraying finishing varnish, drying, cooling and inspecting. In the coating spraying process, completeness of the coating is guaranteed, the abrasion resistance and the corrosion resistance of the shell are improved, the quality of the notebook computer shell coated with the coating is high, and high popularization value is achieved.

Description

technical field [0001] The invention belongs to the technical field of notebook casing processing and application, and in particular relates to a vacuum sputtering method for a notebook casing. Background technique [0002] The notebook case is mainly made of stamping metal material, the appearance has metallic luster, which is more beautiful, but it is easy to be corroded. During the transportation process, the upper case of the notebook needs a stable transportation environment because it has an LED screen. At present, it is mainly achieved by packing shock-absorbing materials in the packing box, which wastes a lot of materials and causes pollution. Scratch damage, so it is necessary to coat the surface of the case with a thin film for protection. [0003] At present, electronic products and automotive interior parts mostly use electroplating, spraying and other processes to achieve surface treatment, so as to obtain colorful and metallic appearance effects.

Problems solved by technology

However, in order to avoid deformation of the plastic element due to high temperature during sputtering, the sputtering temperature should not be high. Due to the problem of sputtering temperature, the thickness of one sputtering must be controlled within 0.7um, resulting in the need to repeat vacuum sputtering many times. , affecting production efficiency
