AI Technical Summary
Technical Problem
Existing technologies for fabricating crater-like structures for electronic device housings involve long CNC machining times, high costs, and difficulty in completely removing tool marks, which affects aesthetics.
Method used
By setting a masking layer on the surface of the raw material and then etching it, the thickness of the target area is made greater than that of other areas, forming a ring structure. This, combined with rotary spray etching and post-processing, reduces process time and cost.
Benefits of technology
It achieves a thin and light shell substrate with a good appearance, reduces costs and time, and the etched texture can be completely removed, improving economic practicality.

Abstract
The invention provides a shell base material manufacturing method, a shell base material, a shell and electronic equipment, and the manufacturing method comprises the steps: arranging a shielding layer on the surface of one side of a raw material, and enabling the shielding layer to cover a target region of the surface of the raw material; performing etching treatment on the raw material to enable the thickness of the target area to be greater than the thickness of other areas except the target area; cutting the target area to form an open hole in the target area, and forming an annular structure by the inner wall of the open hole and the edge of the target area to obtain a semi-finished rough blank; and the semi-finished rough blank is subjected to aftertreatment, and the shell base material is obtained. Other areas except a target area are thinned by etching a raw material, the process time and cost are greatly reduced, and through calculation, compared with the existing CNC machining cost, the cost of manufacturing a shell base material by adopting the method disclosed by the invention is reduced by about 10 RMB; meanwhile, the texture formed by etching treatment is shallow and can be completely removed in the post-treatment process, so that the formed shell base material has better appearance texture.
