Mobile phone shell processing technology, mobile phone shell and mobile phone

Abstract

The invention relates to a mobile phone shell processing technology, a mobile phone shell and a mobile phone. In the process of mobile phone shell processing, a coating film is formed on the first-level appearance surface through spraying and grinding processes or through spraying, grinding, vacuum plating and radium engraving processes, and the coating film covers the antenna and the area other than the antenna on the first-level appearance surface , the thickness of the coating film is less than or equal to 65um. The mobile phone casing includes plastic parts. Antennas and coating films are provided on the first-level appearance surface of the plastic parts. The coating film covers the antenna and the area other than the antenna on the first-level appearance surface. The thickness of the coating film is less than or equal to 65um. The mobile phone of the present invention includes the above-mentioned mobile phone casing. The mobile phone casing processing technology of the present invention can make the mobile phone casing as a whole have a good metal feeling and low cost. The mobile phone casing and the mobile phone of the invention have good hardware feeling and low cost.

Description

technical field [0001] The invention relates to a mobile phone shell processing technology, a mobile phone shell and a mobile phone. Background technique [0002] In order to avoid metal shielding mobile phone signals, there are roughly two types of metal mobile phone shells on the market. One is an all-metal one-piece structure, and the upper and lower antenna segments are filled with plastic. The disadvantage is that the processing cost is high; the other is the main body. Part of it is made of metal, at least the upper and lower sections are made of plastic. Specifically, this type of mobile phone case may include a metal battery back cover, upper and lower plastic decorative strips, and a plastic middle frame. The antenna is set inside the plastic middle frame, and may also include a metal battery cover. The main body and the upper and lower plastic decorative strips (without a plastic middle frame), the antenna is set inside the plastic decorative strips. The disadvanta...

[0002] In order to avoid metal shielding mobile phone signals, there are roughly two types of metal mobile phone shells on the market. One is an all-metal one-piece structure, and the upper and lower antenna segments are filled with plastic. The disadvantage is that the processing cost is high; the other is the main body. Part of it is made of metal, at least the upper and lower sections are made of plastic. Specifically, this type of mobile phone case may include a metal battery back cover, upper and lower plastic decorative strips, and a plastic middle frame. The antenna is set inside the plastic middle frame, and may also include a metal battery cover. The main body and the upper and lower plastic decorative strips (without a plastic middle frame), the antenna is set inside the plastic decorative strips, the disadvantage of this mobile phone case is that the upper and lower plastic parts are too wide, the metal integration is not strong, and the overall hardware feeling of the mobile phone case is poor

[0003] In some existing products, the LDS antenna or PDS antenna will be installed on the first-level appearance surface of the plastic part (plastic middle frame / plastic decorative strip). The surface treatment process paint thickness is generally 100um to cover the antenna marks. Oil accumulates and the C corner on the edge of the phone turns into an R corner, and the overall hardware feeling of the phone case is poor.
