THERMALLY CONDUCTIVE SLEEVES AROUND TGVS FOR IMPROVED HEAT DISSIPATION IN GLASS CORE SUBSTRATES OR GLASS INTERPOSERS

Abstract

Embodiments disclosed herein include electronic packages and methods of assembling such electronic packages. In an embodiment, an electronic package comprises a core, where the core comprises glass. In an embodiment, a first via is through the core, where the first via directly contacts the core. In an embodiment, a second via is through the core, and a sleeve is around the second via. In an embodiment, the sleeve comprises a material with a thermal conductivity that is greater than a thermal conductivity of the second via.
