    Abstract: Methods and a system for proof testing brittle components of electronic devices are disclosed. The method may include positioning the brittle component relative to a probe of a testing system, contacting the probe to a surface of the brittle component at a first location, and applying a first force at the first location using the probe to create a first localized tensile band below the surface of the brittle component. The method may also include contacting the probe to the surface of the brittle component at a second location, distinct from the first location, and applying a second force at the second location using the probe to create a second localized tensile band below the surface of the brittle component.

    Abstract: A cover glass including a center region and an outer region abutting the center region at an interface. The interface inhibits crack propagation from the outer region to the center region and vice versa. In another embodiment the cover glass may include mitigation voids introduced into the cover glass to inhibit crack propagation. The interface may be formed from the mitigation voids.

    Abstract: Systems and methods for polishing a ceramic component using a laser. The ceramic component may include a planar region that is polished using, for example, a mechanical or chemical mechanical polishing operation to produce a polished face. A contoured region that is adjacent to the planar region may be irradiated using a laser to heat the ceramic material within the contoured region. The irradiation may reduce the surface roughness of the contoured region to produce a polished surface. The ceramic component may be heated prior to being irradiated with the laser to reduce thermal gradients within the ceramic component.
