Description

Dazzle various cell-phone back cover

[ technical field ] A method for producing a semiconductor device

The utility model relates to a lid field behind the cell-phone, in particular to dazzle various cell-phone back lid.

[ background of the invention ]

With the advancement of science and technology, electronic products are developed rapidly, the products are changed day by day, and the update iteration cycle is shorter and shorter. The 5G era has come, but the requirement of 5G communication on signals is high, and the rear cover of the existing metal mobile phone has a certain screen-closing effect on the 5G signals, so that the signals are unstable. However, if the plastic or glass rear cover is adopted, although the screen-closing effect can be reduced, the mobile phone can lose the beautiful appearance of the metal rear cover, and the color value of the mobile phone is influenced. Therefore, a colorful mobile phone rear cover is developed.

In order to solve the above problem, the utility model provides a following technical scheme:

the utility model provides a dazzle various cell-phone back lid, its characterized in that is at the bottom of the printing lid, the printing lid on the bottom of have plated TiO in proper order under the vacuum environment₂Layer one, SiO₂Layer one, TiO₂Layer two, SiO₂A second layer; the SiO₂And a transparent substrate layer is also arranged on the second layer.

The colorful mobile phone rear cover is characterized in that the TiO is₂The thickness of the first layer is 40-50 nm.

The colorful mobile phone rear cover is characterized in that the SiO layer is arranged on the rear cover₂The thickness of the first layer is 40-50 nm.

The colorful mobile phone rear cover is characterized in that the TiO is₂The thickness of the second layer is 50-60 nm.

The colorful mobile phone rear cover is characterized in that the SiO layer is arranged on the rear cover₂The thickness of the second layer is 10-20 nm.

The colorful mobile phone rear cover is characterized in that the vacuum degree of the vacuum environment is 3 multiplied by 10^{- 5}Torr。

The colorful mobile phone rear cover is characterized in that the printed cover bottom is made of plastic.

The colorful mobile phone rear cover is characterized in that the transparent substrate layer is made of glass.

The utility model has the advantages of it is following:

1. the utility model relates to a dazzle various cell-phone back lid plates metal oxide layer on the plastics, makes the lid little to the screen of signal behind the cell-phone, makes the lid have multiple colour behind the cell-phone again simultaneously, makes the outward appearance of lid better behind the cell-phone.

2. The utility model relates to a dazzle various cell-phone back lid, the cost is lower.

[ description of the drawings ]

Fig. 1 is a schematic cross-sectional view of the present invention.

[ detailed description ] embodiments

With reference to the attached drawing 1, the utility model provides a dazzle various cell-phone back lid, its characterized in that is including the printing lid end 1, the printing lid end 1 on plated TiO in proper order under the vacuum environment₂Layer one 2, SiO₂Layer one 3, TiO₂Layer two 4, SiO₂Layer two 5; the SiO₂Still be equipped with transparent substrate layer 6 on layer two 5, the cladding material step before beginning, need wash at the bottom of the printing lid 1 to improve surperficial adhesive force, make the cladding material can be more smooth, foretell cleaning method is: carrying out plasma bombardment on the surface of the material by using a Kaufman ion source, wherein the plasma parameters are Ar flow of 40sccm, ion beam current of 500mA and cleaning time of 10 min; in addition, to avoid TiO plating₂Layer one 2 and TiO₂Forming TiO layer by oxygen loss in the second 4 layer, and plating TiO₂Layer one 2 and TiO₂And oxygen is needed to be supplemented when the layer two 4 is formed, and the flow rate of the supplemented oxygen is as follows: the colorful mobile phone rear cover processed in the way is various in color, so that the mobile phone rear cover is better in appearance.

One of the preferable modes of the present invention is the TiO₂The thickness of the layer one 2 is 40-50 nm.

One of the preferred modes of the invention is SiO₂The thickness of layer one 3 is 40-50 nm.

One of the preferable modes of the present invention is the TiO₂The thickness of layer two 4 is 50-60 nm.

One of the preferred modes of the invention is SiO₂The thickness of the second layer 5 is 10-20 nm.

In a preferred embodiment of the present invention, the vacuum degree of the vacuum environment is 3 × 10^-5Torr。

The utility model discloses one of preferred mode does printing cover at the bottom of 1 the material be plastics, less screen-closure signal, make cell-phone 5G signal be superior to lid behind the metal, the cost is lower simultaneously.

The utility model discloses one of preferred mode does transparent substrate layer 6's material be glass, light sees through transparent substrate layer 6 and interferes the light of launching different colours through the film, makes lid have multiple colour behind the cell-phone, if: light blue, dark blue, bright blue, etc.

The present invention is not limited to the precise arrangements described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims. The present invention is not limited to the above embodiments, but may be modified or modified by the common general knowledge or the conventional techniques in the art.
