Abstract:
A laminated glass structure for an electronic device includes: a core glass layer having a first coefficient of thermal expansion (CTE); and a plurality of clad glass layers, each having a CTE that is lower than or equal to the first CTE of the core glass layer. A first of the clad glass layers is laminated to a first surface of the core glass layer and a second of the clad layers is laminated to a second surface of the core glass layer. Further, the total thickness of the core glass layer and the clad glass layers ranges from about 0.1 mm to about 3 mm. In addition, each of the first of the clad layers and the core glass layer comprises a loss tangent of 0.006 or less for signals having a frequency of 1 GHz to about 100 GHz.
