Abstract

The invention relates to a manufacturing process of electroplating an anti-reflection sapphire film onto a cell phone cover plate, wherein the process includes the processes of: surface reinforcement of glass, ultrasonic cleaning, vacuum electroplating, vacuum gas phase film plating and microwave hot-particle gas-phase deposition. By electroplating the anti-reflection sapphire film onto a common glass plate, the glass plate is comparable with sapphire glass in hardness, and meanwhile, the defect of low light transmittance of the sapphire is overcome. The product, compared with the sapphire, is also greatly improved in yield. The creative technology can replace a simple sapphire process. The product is convenient and quick to process and has better advantages than the sapphire in cost.

Description

technical field [0001] The invention relates to the field of mobile phones, in particular to a manufacturing process of electroplating anti-reflection sapphire film on a cover plate of a mobile phone. Background technique [0002] Today, as the mobile phone market is expanding, the competition in the processing of mobile phone cover plates is also intensifying. Major mobile phone companies are constantly developing new processes, hoping to use new processes to reduce production costs and improve the company's market competitiveness. In the modern production process, the use of ordinary glass for the cover plate of mobile phones can no longer meet the technical requirements. More and more brands use sapphire glass with excellent performance, but its expensive material cost is prohibitive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method that not only increases the light transmittance of the mobile phone co...
