Abstract

The invention discloses a terminal, terminal shell, and shell processing method. The shell comprises a metal body, the outer surface of which is a mirror polished surface, and a PVD plated film layer,which is arranged on the mirror polished surface through PVD processing technology through plating. According to the terminal shell, the PVD plated film layer is arranged on the mirror polished surface of the metal body through plating. The PVD plated film layer is relatively small in thickness and good in uniformity. Therefore, the shell provides a high light metal effect, and the processing yield rate and appearance aesthetic property of the shell are improved.

Description

Technical field [0001] The present invention relates to the technical field of communication equipment, in particular, to a terminal, a housing of the terminal, and a processing method of the housing. Background technique [0002] In the related art, in order to achieve a bright appearance effect of the metal shell of the terminal, the surface of the metal shell is generally polished and then anodized. After anodizing, the surface of the metal shell needs to be polished or planarly polished twice. Due to the thick film thickness and poor uniformity during the anodization, the yield of the surface of the metal shell during the second polishing or grinding is low, and the second time The unevenness of polishing will cause the color layer to be different and affect the appearance of the product. Summary of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present invention propo...
