Processing method of clearance area of ​​housing, housing and mobile terminal

Abstract

The invention discloses a method for processing a clearance area of ​​a casing, which includes providing a casing, the casing is made of a signal shielding material and has a preset area, and the preset area includes a first surface and a second surface arranged opposite to each other; At least one support structure is processed on the first surface of the predetermined area; the laser cutting machine is aligned with the second surface of the predetermined area, and a predetermined number of micro-slits are cut out of the predetermined area, and the predetermined number of micro-slits are connected to each other Arranged side by side at intervals; fill non-signal shielding material in each micro-slit to obtain a clearance area; cut off the support structure. The method provided by the embodiment of the present invention cuts a preset number of micro-slits on the casing by laser, and forms a clearance area by filling the micro-slits with material to obtain a clearance area of ​​a specific shape. At the same time, due to the narrow micro-slits , reducing the proportion of the non-signal shielding material of the housing, and ensuring the integrity of the 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, a certain clearance area is generally processed by CNC machine tools on the back of the metal mobile phone for the passage of radio frequency signals. However, the inventor found that the clearance area is limited by the cutting tool or control mode of the CNC machine tool when processing the above process. It cannot process the headroom area of ​​a specific shape, or the area of ​​the headroom area is often large, which affects the overall sense of the mobile phone. Contents of the i...
