Abstract:
Methods for chemically strengthening a cover for an electronic are disclosed. The methods include removing material from a mounting surface of the cover to counteract warping of the mounting surface due to ion exchange. The chemically strengthened covers have a high bend strength and allow a strong seal to be formed between the cover and an enclosure component.
