Abstract

The invention discloses a processing method for the clearance area of ​​a shell, which comprises: providing a shell, the material of which is a conductive material; oxidizing the shell so that an oxide layer is formed on the shell; Protective layer; remove the protective layer and oxide layer in the preset area on the inner surface of the shell; remove the conductive layer in the preset area; remove the remaining protective layer of the shell; make a brightening layer in the clearance area of ​​the shell. The processing method of the clearance area of ​​the housing provided by the embodiment of the present invention removes the conductive layer in the preset area to form a clearance area capable of passing the radio frequency signal of the antenna, and makes a brightening layer on the clearance area, so that the clearance of the housing The color and brightness of the region and the conductive region of the housing are the same, that is, the headroom region has a strong concealment, thereby improving the overall appearance of the housing. The invention also provides a casing and a mobile terminal.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a processing method for a clearance area of ​​a housing, the housing and a mobile terminal. Background technique [0002] With the development of technology and market demand, the demand for all-metal mobile phones is increasing. Although the all-metal mobile phone is beautiful, its metal shell will block the radio frequency signal of the antenna to a certain extent. [0003] In the prior art, gaps are generally machined on the back of metal mobile phones by CNC machine tools and plastics are injected into the gaps to form clearance areas for radio frequency signals to pass through. , the appearance is anodized, which makes the color difference between the non-clear area and the clear area large, and destroys the integrity of the appearance of the shell. Contents of the invention [0004] The object of the present invention is to provide a method for processing the clearan...
