METHOD OF ENGRAVING GLASS BASE

Abstract

The multi-layer glass-based etching method involves classifying multiple glass-based layers into groups based on the average thickness of the corresponding glass-based layer. The maximum difference between the first average thickness of the first layer and the second average thickness of the second layer of the first group among the multiple groups is less than or equal to a predetermined threshold. The method may also include classifying the first group into subgroups based on the total thickness variation. The glass-based etching method involves placing the glass-based layer in a fixture, where the second edge is closer to the perimeter support than the first edge is to the perimeter support. The glass-based etching method involves placing the glass-based layer in a fixture, where the first edge is closest to the top surface of the fixture.
