Embodiment 1

[0032] This embodiment provides a planar 2D glass back cover with an antenna, which is manufactured by the following steps.

[0033] S1. Spray a conductive paste layer on the protective ink layer of the glass back cover.

[0034] The conductive paste layer is produced by spraying photosensitive silver paste on the protective ink layer of the flat 2D glass back cover. The photosensitive silver paste includes 70wt% of silver powder and 30wt% of binder, and its viscosity is 1000-1500cps.

[0035] The entire spraying operation is carried out at a temperature of 40° C. and a pressure of 0.1 MPa. The surface on which the antenna will be installed is sprayed on the front, and the number of sprays is 1 to 3 times until a uniform and flat conductive paste layer is obtained.

[0036] After the spraying of the conductive paste layer is completed, the conductive paste layer is baked at 120° C. for 30 minutes. Until the shape of the conductive paste layer is basically fixed.

Abstract

The invention discloses a method for manufacturing an antenna on a glass back cover, and belongs to the field of electronic equipment. The method comprises the steps of spraying a protective ink layer on the glass back cover with a conductive slurry layer; forming the conductive slurry layer into to an antenna loop in a portraying manner; and covering the antenna loop with an insulating coating layer. By adoption of the method, the glass back cover is successfully integrated with the antenna function; the binding force between the photosensitive conductive slurry and the glass back cover is strong, so that the finished glass back cover can be directly sprayed with the conductive slurry without adding other transitional layer; by virtue of the method, the antenna loop can be accurately portrayed, and compared with the conventional printing process, the dimensional precision of the antenna is higher; and meanwhile, the process is not limited by the shape of the glass back cover, so that setting of the antenna on a plane, a cambered surface, a four-side hook face and a two-side hook surface can be realized, and the application range is extremely wide. The invention also provides the glass back cover equipped with the antenna; the glass back cover is integrated with the antenna function by adoption the method; and the glass back cover has the characteristics of lighter and thinner appearance, better communication effect, rich and diversified shapes and the like.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a method for manufacturing an antenna on a glass back cover and a glass back cover with the antenna. Background technique [0002] Antenna design occupies a very important position in the design of terminal products, and is a very important part that affects consumer experience. Conventional antenna structures include bracket type and attached type. The bracket antenna is composed of a plastic bracket and a metal sheet (radiator). The metal sheet and the plastic bracket are fixed by hot melting. The plastic is usually made of ABS and PC materials, and the metal is usually made of copper-plated, phosphor bronze, stainless steel, etc. Adding two PINs on the top is costly; the attached antenna attaches the metal sheet (radiator) to the back shell of the product, and the fixing method generally adopts a hot-melt structure, or it can also be connected by adhesive. [0003] In the ...
