Surface treating method of electronic apparatus shell

Abstract

The invention relates to a surface treatment method of an electronic device outer shell, which belongs to the electromechanic field. The method comprises the following steps: (a) a sputtering layer is produced on the surface of a transparent substrate through sputtering; (b) dyeing areas are produced on the sputtering layer through flocking. The method has the advantages that the surface of the transparent substrate has the metal feel of thin film; the sputtering layer on the surface of the substrate does not interfere with the transmission of the wireless signal, which keeps good communication quality; apart from having metal feel and metal effect through the sputtering layer, the substrate can also produce patterns and aesthetics in different colors through the dyeing areas, so as to produce different effect on the sputtering layer and prevent the cold negative impression of the metal effect on people.

Description

technical field [0001] The invention relates to electromechanical products, in particular to a surface treatment method for an electronic device casing. Background technique [0002] As we all know, for the purpose of light weight and convenient manufacturing, most of the casings of electronic devices are made of plastic or plastic materials, but the casings made of plastic materials have poor visual or touching effects and textures. To make the plastic casing of the electronic device have a good visual aesthetic and texture, a metal layer is produced on the plastic casing by plastic electroplating, and a metal layer is produced on the surface of the plastic casing by plastic electroplating, such as the United States Disclosed in Patent 6,045,866. [0003] However, the metal layer plated by the plastic electroplating method can only be less active metals such as copper and nickel, and it is more difficult to use more active metals such as aluminum on the plastic electroplat...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to provide a surface treatment method for the shell of an electronic device, which solves the problem that the common method cannot achieve the thin film of aluminum or aluminum alloy on the plastic shell, and can only produce a monotonous metallic texture on the plastic material, which cannot meet the needs of consumers. The needs of consumers, poor market competitiveness, and the formation of a shielding effect on the flat panel antenna, resulting in a decrease in the efficiency of the antenna receiving signals, etc.
