<p>Aluminum filled via disks are manufactured utilizing a plurality of drilled substrates placed into a metal can in a stacked, interdisposed assembly with a corresponding number of graphite molds. Aluminum infiltration ingots are added and the can is heated to a temperature to melt the ingots. The molten aluminum is pressurized so that it flows into the vias. The substrates are then cooled, removed from the can, separated from between the graphite molds, and the flat surface faces are ground and polished to expose the filled vias.</p> |
