Title: METHOD FOR MACHINING CLEARANCE AREA OF HOUSING, HOUSING AND MOBILE TERMINAL
Abstract:
A method for machining a clearance area (10) of a housing (100), a housing (100) and a mobile terminal. The method comprises: providing a housing (100), the housing (100) being made of a signal shielding material and having a pre-set area, and the pre-set area of the housing (100) having a first surface and a second surface arranged opposite to the first surface (S101); forming at least one support structure on the first surface, so that the support structure protrudes from the first surface (S103); cutting out, on the first surface, a pre-set number of micro slits (1) by using a laser cutting machine, the pre-set number of micro slits (1) penetrating from the first surface to the second surface and being spaced in parallel to each other, and each support structure spanning the pre-set number of micro slits (1) to connect the housing (100) into a whole (S105); filling each of the micro slits (1) with a non-signal shielding material (2) to obtain a clearance area (10) (S107); and cutting away the support structure (S109). According to the method, by cutting out, on a housing (100), a pre-set number of micro slits (1) by using a laser, the proportion of a non-signal shielding material (2) of the housing (100) is reduced, and the appearance integrity of the housing (100) is ensured.
