preparation example Construction

[0023] The invention provides a method for preparing a mobile phone back screen with an antenna, comprising the following steps:

[0024] Step 1. Provide a glass back screen;

[0025] Step 2, screen-print the metallizable ink on the glass back screen according to the designed antenna pattern, and form an ink layer after drying, and the metallizable ink contains electroless plating active substances and organic components;

[0026] Step 3, using energy beams to irradiate the ink layer to expose the electroless plating active material to form an electroless plating activation area;

[0027] Step 4, performing electroless copper plating on the surface of the electroless-plating activation area, and forming a copper-plated antenna layer on the glass back screen.

[0028] The inventors of the present invention unexpectedly found that by screen-printing the metallizable ink on the glass back screen according to the designed antenna pattern, the metallizable ink is self-made ink con...

Embodiment 1

[0053] This embodiment 1 is used to illustrate the mobile phone back screen with antenna and its preparation method;

[0054] Step 1: Provide a glass back screen, spray a layer of colored primer on the surface of the glass back screen, the spray thickness is 30 μm, the colored primer is self-made, and the formula is as follows: 30 parts by weight of hydroxyl acrylic resin; 15 parts by weight of polyurethane resin; 10 parts by weight of epoxy resin; 10 parts by weight of carbon black; 17.5 parts by weight of cyclohexanone; 15 parts by weight of butyl ester; 1 part by weight of leveling aid; Both are commercially available; dry the sprayed colored primer at 80°C for 3 hours to obtain a colored primer layer with a thickness of 30 μm;

[0055] Step 2: Screen-print the metallizable ink on the surface of the colored primer according to the designed antenna pattern. The mesh number of the screen plate is 300 mesh, and the printing thickness is 25 μm. The metallizable ink is self-made...

Embodiment 2

[0061] This embodiment 2 is used to illustrate the mobile phone back screen with antenna and its preparation method;

[0062] Step 1: Provide glass back screen;

[0063] Step 2: Screen-print the metallizable ink on the surface of the glass back screen according to the designed antenna pattern. The mesh number of the screen plate is 300 mesh, and the printing thickness is 25 μm. The metallizable ink is self-made, and the formula is as follows : 20 parts by weight of hydroxyl acrylic resin; 35 parts by weight of polyurethane resin; 10 parts by weight of epoxy resin; CuSeO, an active material for electroless plating 4 12 parts by weight; 20 parts by weight of isophorone; 2 parts by weight of leveling aids; 0.5 parts by weight of dispersion aids; 0.5 parts by weight of defoaming aids, the above raw materials are commercially available; ;Dry the metallizable ink at 80°C for 1h to obtain an ink layer with a thickness of 20μm;

[0064] Step 3: Use Han’s YLP-20 laser to irradiate t...

Abstract

The invention provides a method for preparing a mobile phone back screen with an antenna, comprising the following steps: step 1, providing a glass back screen; step 2, screen-printing metallizable ink on the glass back screen according to the designed antenna pattern , forming an ink layer after drying, the metallizable ink contains an electroless plating active substance; step 3, using energy beams to irradiate the ink layer, exposing the electroless plating active substance to form an electroless plating activation area; step 4 1. Carrying out electroless copper plating on the surface of the activation region capable of electroless plating, and forming a copper-plated antenna layer on the glass back screen. The present invention also provides a mobile phone back screen with an antenna manufactured by the above preparation method, including a glass back screen and an antenna formed on the glass back screen, and the antenna is a copper-plated antenna. The preparation method of the present invention can realize the manufacture of antennas on the surface of the glass back screen, so that the back screen of the mobile phone not only meets the fashionable appearance and good texture, but also meets the practical requirements.

Description

technical field [0001] The invention relates to the field of mobile phones, in particular to a mobile phone back screen with an antenna and a preparation method thereof. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the public has higher and higher requirements for digital products such as mobile phones, not only focusing on their functionality, but also on the fashion and texture of their appearance. Plastic and metal mobile phone back shells have caused people's aesthetic fatigue. Therefore, in recent years, major mobile phone manufacturers have begun to use glass as the back screen material. [0003] Those skilled in the art know that the existing metal mobile phone back shells can be provided with antennas on the mobile phone back shells, and the existing plastic mobile phone back shells can also form a metal layer on the plastic surface, and then install the metal layer on the metal Antenn...
