Glass rear cover and making method thereof

Abstract

The invention provides a glass rear cover, which comprises glass, a transparent basement membrane and a transparent photoresist pattern formed on one-side surface of the transparent basement membrane,wherein the other-side surface of the transparent basement membrane is bonded on the glass; the transparent photoresist pattern comprises multiple single pattern blocks arranged on the transparent basement membrane in an array mode; centers of the multiple single pattern blocks located in the same row are located on a first straight line; centers of the multiple single pattern blocks located in the same column are located on a second straight line; the first straight line is vertical to the second straight line; the cut sizes of the single pattern blocks on the first straight line and the second straight line are 20 to 50 mum; and the minimum gap between any adjacent two single pattern blocks in the row or the column is 20 to 50 mum. Thus, a glaring pattern can be formed on the glass, theenvironmental pollution and the harm to the human body caused by the use of corrosive substances when the glass is etched directly can be avoided, and the glass rear cover is green. Besides, the invention also provides a method of making the glass rear cover.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment accessories, and in particular relates to a glass back cover and a preparation method thereof. Background technique [0002] With the improvement of consumption level, consumers not only pay attention to the quality of electronic products, but also pay more and more attention to the decorative effect of the surface of the shell. The shell with glare pattern is very popular among consumers because of its novel appearance. The existing method of forming glare patterns on the casing of electronic products is usually to coat HF ​​(hydrofluoric acid) resistant photoresist on the back cover glass, etch the back cover glass after forming the photoresist pattern after the yellow light process, and peel off the back cover glass. After removing the HF photoresist, the glass back cover with glare texture can be formed. However, this method of operation will use corrosive substances such as HF,...
