Abstract
Methods and apparatus to reduce cracking in glass cores are disclosed. An example apparatus includes a package substrate comprising a glass core having an opening extending between first and second surfaces of the glass core, the first surface opposite the second surface, and a conductive material, a first portion of the conductive material within the opening, a second portion of the conductive material protruding beyond the first surface of the glass core, a first surface of the first portion in continuity with a second surface of the second portion.
Claims20
An apparatus comprising:
- a glass core having an opening extending between first and second surfaces of the glass core, the first surface opposite the second surface;
- and
- a conductive material, a first portion of the conductive material within the opening, a second portion of the conductive material protruding beyond the first surface of the glass core, a first surface of the first portion in continuity with a second surface of the second portion.
An apparatus comprising:
- a glass core having a hole extending through opposing sides of the glass core;
- and
- a through-glass via extending through the hole, the through-glass via defined by an elongate shaft of conductive material, the elongate shaft having a length greater than a thickness of the glass core such that a portion of the elongate shaft is positioned outside the hole.
A package substrate comprising:
- a glass core having a surface with a cavity;
- and
- metal at least partially within the cavity, the metal having a first surface, a first portion of the first surface in the cavity and adjacent to a wall of the cavity, a second portion of the first surface outside of the cavity and protruding away from the surface of the glass core, the second portion contiguous with the first portion.
