Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.

According to various embodiments described herein, an article comprises a glass or glass-ceramic substrate having a first major surface and a second major surface opposite the first major surface, and a via extending through the substrate from the first major surface to the second major surface over an axial length in an axial direction. The article further comprises a helium hermetic adhesion layer disposed on the interior surface; and a metal connector disposed within the via, wherein the metal connector is adhered to the helium hermetic adhesion layer. The metal connector coats the interior surface of the via along the axial length of the via to define a first cavity from the first major surface to a first cavity length, the metal connector comprising a coating thickness of less than 12 μm at the first major surface. Additionally, the metal connector coats the interior surface of the via along the axial length of the via to define a second cavity from the second major surface to a second cavity length, the metal connector comprising a coating thickness of less than 12 μm at the second major surface and fully fills the via between the first cavity and the second cavity.
