In the orientation of FIG. 2A, the overall thickness 214 extends in a z-direction of a reference cartesian coordinate system (e.g., a vertical or stack-up/build-up direction in the orientation of FIG. 1). In some examples, the overall thickness 214 can be between 100 micrometers (μm) and 1 millimeter (mm).). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention was made to combine the teachings of KAMGAING of having a substrate, comprising: a glass core; a plurality of glass layers on the glass core, wherein some of the glass layers are above the glass core and some of the glass layers are below the glass core; a plurality of conductive traces, wherein the conductive traces are in the glass core and at least some of the glass layers; and a plurality of conductive contacts on one or more surfaces of the substrate, with the teachings of Darmawikarta of having wherein the glass core has a thickness ranging from approximately 100-1000 microns.
