Non-contact polishing techniques for reducing roughness on glass surfaces

摘要

Apparatus, systems and methods for reducing surface roughness on surface of a glass member using a non-contact polishing process are disclosed. According to one aspect, a method for processing a glass member suitable for use in a handheld electronic device includes obtaining the glass member and chemically strengthening the glass member. The glass member has at least one surface, and chemically strengthening the glass member increases roughness associated with the at least one surface. The method also includes applying a first non-contact polishing process to the glass member after chemically strengthening the glass member. Applying the first non-contact polishing process reduces the roughness associated with the at least one surface.

主权项

1. A method for processing a glass member suitable for use in a handheld electronic device, the method comprising:
obtaining the glass member, the glass member having at least one surface, the at least one surface including a top surface; chemically strengthening the glass member, wherein chemically strengthening the glass member increases roughness associated with the at least one surface; selectively applying a first non-contact polishing process to a portion of the top surface of the glass member after chemically strengthening the glass member, wherein applying the first non-contact polishing process reduces the roughness associated with selected areas of the at least one surface; and polishing non-selected areas of the at least one surface using a second non-contact polishing process, wherein a composition of the first non-contact polishing process is different from a composition of the second non-contact polishing process.
