Problems solved by technology

The current strengthening treatment is generally divided into two times. During the second strengthening, the strengthening depth is very thin. In the subsequent glass processing process (such as grinding, etc.), the strengthening layer formed by the second strengthening treatment is eliminated, resulting in glass strength that does not meet the requirements.

Embodiment Construction

[0019] The glass obtained by the processing method of the glass substrate provided by the present invention is applied to consumer electronic products as a protective cover or backplane, for example, the glass substrate can be used as a cover or backplane of a smart phone.

[0020] Such as figure 1 As shown, in one embodiment, the glass substrate processing method provided by the present invention includes sequentially performing step S110: primary strengthening treatment; step S120: grinding; and step S130: secondary strengthening treatment on the provided glass substrate.

[0021] The glass substrate provided by the present invention refers to silicate glass containing alkali metal ions, such as lithium ions or sodium ions. The glass substrate has opposing first and second surfaces. The glass substrate also has side surfaces connecting the first surface and the second surface. Suitable for the development trend of light and thin consumer electronic products, the thickness ...

Abstract

The invention relates to a processing method of a glass substrate. The processing method of the glass substrate comprises the following steps: providing the glass substrate, wherein the glass substrate is provided with a first surface and a second surface which are opposite to each other; performing primary strengthening treatment on at least one surface of the first surface and the second surface of the glass substrate; grinding the glass substrate subjected to primary strengthening treatment; and performing secondary strengthening treatment on at least one surface of the ground glass substrate. Secondary strengthening treatment is conducted after grinding, so the processing method avoids the fact that a thin pressure stress layer formed by secondary strengthening treatment is eliminated in the grinding processing process as compared with the traditional processing method, the effect of strengthening treatment is retained, and the strength of the glass substrate is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a method for processing a glass substrate. Background technique [0002] The popularization of electronic products such as smart phones and watches equipped with touch screens has made manufacturers scramble to launch differentiated products in order to attract consumers. Glass is more popular as a casing material for electronic products because of its texture. But the glass casings of electronic products are prone to shattering due to accidental drops. Therefore, when glass is applied to the housing of electronic products, it is necessary to strengthen the glass. The current strengthening treatment is generally divided into two times. During the second strengthening, the strengthening depth is very thin. In the subsequent glass processing process (such as grinding, etc.), the strengthening layer formed by the second strengthening treatment is eliminated, resultin...
