Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] Please also refer to Figure 1 to Figure 3 , the manufacturing method of the mobile phone glass rear cover provided by the present invention is now described. The manufacturing method of the glass back cover of the mobile phone comprises the following steps carried out in sequence:

[0034] S1. Coating a layer of transparent resin that fully covers the plain glass 1 on the upper surface of the plain glass 1, and curing the transparent resin to obtain a protective photoresist layer 2;

[0035] S2. Coating a metal film 3 on the upper surface of the protective photoresist layer 2 by vacuum sp...

Abstract

The invention discloses a method for manufacturing a glass back cover of a mobile phone, comprising: coating and curing a layer of transparent resin fully covering the plain glass on the upper surface of the plain glass to obtain a protective photoresist layer; Coating a layer of metal film on the upper surface of the metal film; making a transition photoresist layer on the upper surface of the metal film; using an etching solution to etch away the part of the metal film exposed to the transition photoresist layer; stripping the transition photoresist layer; printing and curing full coverage Protect the photoresist layer and the ink of the metal film to obtain the substrate. Before vacuum sputtering on the plain glass, a layer of transparent resin is cured on the plain glass to obtain a protective photoresist layer, which greatly improves the strength of the glass back cover, and the metal film is firmly attached to the protective photoresist layer to avoid Separation between layers, and then using the transitional photoresist layer to assist in the etching of the metal film on the glass back cover by vacuum sputtering, the coating appearance of any shape can be designed; the strength of the glass back cover of the mobile phone is greatly improved, and the glass is not easy to break when dropped broken.

Description

technical field [0001] The invention belongs to the field of touch screens, and in particular relates to a method for manufacturing a glass back cover of a mobile phone. Background technique [0002] In recent years, more and more mobile phones have adopted glass back covers. The LOGO production and glare texture production of the glass back cover will use the glass coating process. Compared with the plastic or metal case, its appearance is more beautiful, and it feels better. At present, all manufacturers are directly vacuum sputtering metal coating on plain glass to obtain LOGO coating, glare texture coating, etc., and then make a black substrate. The disadvantage of this solution is that when coating directly on glass, the high-speed operation When the atoms strike the surface of the glass substrate, they greatly reduce the strength of the glass surface, making the glass more susceptible to shattering. Contents of the invention [0003] One of the objectives of the pr...
