Abstract
An article including a glass having that includes SiO2, Al2O3, and B2O3 and least one of Li2O, Na2O, K2O, MgO, CaO, SrO, BaO, SnO2, ZnO, La2O3, F, and Fe2O3, wherein the glass includes a dielectric constant of about 10 or less and/or a loss tangent of about 0.01 or less, both as measured with signals at 10 GHz.
Claims11
An article, comprising:
- copper;
- and
- a glass electrically-insulating layer supporting the copper, wherein the glass electrically-insulating layer comprises a glass comprising by mole percent of oxides:
- SiO2 from about 60% to about 80%;
- Al2O3 from 0% to about 13%;
- B2O3 from about 7% to 20%;
- from above 0% to about 1% of at least one fining agent;
- and
- RO from 3% to about 15%, wherein the RO are selected from the group consisting of CaO, MgO, BaO, and/or SrO;
- wherein a ratio of MgO to RO is at least 0.38, but wherein the RO are mixed species such that the ratio of MgO to RO is no more than 0.86;
- and
- wherein a ratio of B2O3:(Al2O3+SiO2) is from about 0.13 to about 0.35;
- and
- one or more polymeric substrate layers in combination with the glass electrically-insulating layer.
