Manufacturing method for ultrathin glass

Abstract

A manufacturing method for ultrathin glass includes the following steps: providing at least one glass; fixing the glass in an upright standing state; atomizing an etching solution to obtain an atomized etching solution; and conveying the atomized etching solution to at least one nozzle of at least one liquid guiding tube through the at least one liquid guiding tube, and sprinkling the atomized etching solution onto the surface of the glass through the at least one nozzle. The flat ultrathin glass can be manufactured through the method.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a method for manufacturing ultra-thin glass. Background technique [0002] With the requirements of thin, light and small electronic products, such as handheld devices, the demand for ultra-thin glass is getting higher and higher. [0003] Because the thickness of ultra-thin glass is very small, it is not easy to manufacture. The current manufacturing method of ultra-thin glass is to perform a thinning process on a glass with a large thickness to make its thickness smaller, and the thinning process mainly uses Etching means to etch the thickness of the glass. [0004] However, there are too many factors in the etching process that will affect the manufacturing yield of ultra-thin glass. There are many conditions that are difficult to control in the etching solution, such as the disturbance of the etching solution, the spray pressure of the etching solution, the flow rate of the et...

Problems solved by technology

[0004] However, there are too many factors in the etching process that will affect the manufacturing yield of ultra-thin glass. There are many conditions that are difficult to control in the etching solution, such as the disturbance of the etching solution, the spray pressure of the etching solution, the flow rate of the etching solution, and the temperature of the etching solution, etc. Wait

[0005] For example, when the conditions of the above-mentioned etching solution are controlled inaccurately, the surface flatness of the manufactured ultra-thin glass will be poor. Once the surface flatness is poor, the yield rate of subsequent electronic components manufactured on ultra-thin glass will also be poor. , and even lead to the problem of deformation or easy cracking of ultra-thin glass

[0006] Therefore, it is indeed necessary to propose a solution to the above-mentioned problem of poor manufacturing yield of ultra-thin glass
