Document Type and Number:
WIPO Patent Application WO/2018/010517
Kind Code:
A1
Abstract:
A method for machining the clearance area of a shell, comprising: providing a shell, the material of the shell being an electrically conductive material (S110); implementing oxidisation treatment of the shell (S120) to form an oxidised layer on the shell; spraying a protective layer on the oxidised layer (S130); removing the protective layer and the oxidised layer of a preset area on the inner surface of the shell (S140); removing an electrically conductive layer of the preset area, so that the preset area forms a clearance area through which radio frequency signals of an antenna can pass (S150); removing the remaining protective layer on the shell (S160); forming a brightening layer on the clearance area of the shell (S170), such that the colour and brightness of the clearance area of the shell and the electrically conductive area of the shell are the same, so that the clearance area is hidden and the integrity of the appearance of the shell is improved.
