preparation example Construction

[0027] In a second aspect, the present invention provides a method for preparing a metal casing of an electronic product formed with an antenna slot, the method comprising the following steps:

[0028] (1) The metal layer is subjected to hard anodic oxidation treatment and ink spraying treatment in sequence to form a hard anodic oxidation layer and an ink layer respectively;

[0029] (2) An antenna groove is formed on the back side of the product obtained through step (1), so that the antenna groove penetrates the back ink layer, the back hard anodized layer and the metal layer of the product in the thickness direction, and makes the front hard The inner side of the quality anodized layer is exposed;

[0030] (3) Remove the ink layer and fill the antenna groove with non-conductive material.

[0031] In the method of the present invention, the method for the hard anodic oxidation treatment is not particularly limited, and may be various hard anodic oxidation treatment methods ...

Embodiment 1

[0058] This embodiment is used to illustrate the mobile phone aluminum alloy casing formed with the antenna slot and the preparation method thereof according to the present invention.

[0059] (1) Alkaline etching treatment: Cut the 5-series aluminum material with a thickness of 0.5mm in the aluminum alloy layer 1 into aluminum alloy sheets of 5cm*3.5cm. Alkaline etching in the solution for 1.5min, then wash twice with deionized water;

[0060] (2) Light-emitting treatment: at 25°C, put the aluminum alloy sheet obtained in step (1) into light-emitting liquid (based on 1L of light-emitting liquid, the amount of 65% by weight concentrated nitric acid is 300ml) for 2 minutes, and then deionized water Wash 2 times;

[0061] (3) Oxidation treatment: put the aluminum alloy sheet obtained in step (2) into an oxidation tank, wherein, at 10° C., adopt a forward square wave pulse with a duty cycle of 80%, a frequency of 800 Hz, and a current density of 5 A / dm 2 , the aluminum alloy ...

Embodiment 2

[0071] This embodiment is used to illustrate the mobile phone aluminum alloy casing formed with the antenna slot and the preparation method thereof according to the present invention.

[0072] (1) Alkaline etching treatment: Cut the 5-series aluminum material with a thickness of 0.5mm in the aluminum alloy layer 1 into aluminum alloy sheets of 5cm*3.5cm. Alkaline etching in the solution for 2 minutes, and then washed twice with deionized water;

[0073] (2) Light-emitting treatment: at 20°C, put the aluminum alloy sheet obtained in step (1) into light-emitting liquid (based on 1L of light-emitting liquid, the amount of 65% by weight concentrated nitric acid is 400ml) for 1min, and then rinse with deionized water Wash 2 times;

[0074] (3) Oxidation treatment: put the aluminum alloy sheet obtained in step (2) into an oxidation tank, wherein, at 5°C, use a forward square wave pulse with a duty cycle of 50%, a frequency of 500Hz, and a current density of 2A / dm 2 , the aluminu...

Abstract

The invention discloses an electronic product metal shell formed with an antenna slot and a preparation method of the electronic product metal shell. The electronic product metal shell comprises a metal layer and hard anodic oxidation layers, wherein the hard anodic oxidation layers wrap the surface of the metal layer; the antenna slot runs through the back hard anodic oxidation layer and the metal layer of the electronic product metal shell in the thickness direction; the inner side of the front hard anodic oxidation layer is exposed; and the antenna slot is filled with a non-conducting material. The antenna slot formed in the electronic product metal shell disclosed by the invention is invisible in appearance; the cleanliness and the continuity of the appearance of the electronic product metal shell are ensured; and the overall metal texture of the electronic product metal shell is not destroyed.

Description

technical field [0001] The invention relates to the field of electronic product preparation, in particular to an electronic product metal shell formed with an antenna slot and a preparation method thereof. Background technique [0002] At present, in order to solve the problem of fuselage signal shielding, electronic products such as metal mobile phones often adopt the method of opening and injecting antenna slots on the back cover of the mobile phone, such as the upper and lower antenna slots of HTCONE, and the side antenna slots of iphone5 / 5s. However, the aforementioned method of opening an antenna slot on the metal casing of the electronic product (such as the metal mobile phone back cover) and injecting molding has caused certain damage to the overall structure of the metal casing of the electronic product (such as the metal mobile phone body), affecting its appearance. Cleanliness and continuity. At the same time, the visible plastic on the metal casing of electronic ...
