Abstract:
1. A method of manufacturing a via disk, the method comprising the steps of: providing a substrate comprising a non-porous material having defined therethrough at least two open vias, each of the vias extending from a first side of the substrate to a second side of the substrate, and having a first opening at the first side of the substrate and a second opening at the second side of the substrate; providing an electrically conductive material; melting the electrically conductive material; and subsequently, exposing at least one surface of the substrate to the molten electrically conductive material under conditions of elevated pressure and temperature, such that the electrically conductive material flows into the at least two open vias in a molten state free of solid state material to fill the at least two open vias, thereby forming at least two isolated regions of electrical conductivity through the substrate.
