Abstract

The invention discloses a method for etching a single side of a glass panel, and belongs to the technical field of glass panel etching methods. The processing method includes the steps: firstly, selecting and cleaning a glass panel with the thickness of 0.2-0.5 mm for 5-10 min at the temperature of 20-30 DEG C, and naturally airing the glass panel for use after the cleaning; covering a layer of protective paper on a non-etched surface of the cleaned glass panel, covering a layer of film on the protective paper, completely covering the protective paper with the film, and finally adhering a back plate to the film by using an acid-resistant adhesive tape; hoisting the treated glass panel by adopting a fence for glass etching, suspending the glass panel in the air, and then etching the etched surface of the glass panel; then carrying out demolding treatment on the etched glass panel; and finally, cleaning the de-molded glass panel. According to the method disclosed by the invention, the glass adhered to the back plate in the etching process does not have the conditions of abrasion, deformation, rupture and the like.

Description

technical field [0001] The present invention relates to the technical field of etching methods for glass panels, in particular to a single-sided etching method for glass panels. Background technique [0002] Glass thinning is a manifestation of the trend towards thinner and lighter global consumer electronics products. In terms of smartphones and notebook computers, it is also gradually developing in a more ultra-thin direction. Since the glass thinning mainly uses hydrofluoric acid for chemical etching and thinning, due to the film viscosity and edge unsupported during the production process, the glass becomes thinner with poor support, deformation, wear, rupture and acid seepage. During the product inspection after etching, there are adverse risks such as clamping of the contact points of the teeth, jumping teeth and cracking. [0003] At present, many factories use conventional film thinning, etc., because many immersion etching tanks have great limitations in the fluidi...
