Abstract: Components of an electronic device, such as glass articles, are susceptible to breakage, especially in regions where machining a glass article has created flaws. Chemical strengthening can be performed to create deeper compression layers at regions of a glass article that have been machined, include and/or are adjacent to an edge feature, have greater surface roughness, and/or have more or deeper cracks.
