Claim:
1. A method for creating electrically or thermally conductive vias in both vertical and horizontal orientations in a dielectric material, the method comprising the steps of: (a) depositing a dry powder comprising metallic particles on a planar surface of a dielectric material having through or blind vias; (b) polishing the powder of metallic particles into the through or blind vias; (d) applying a non-polar solvent to one or more planar surfaces of the dielectric material; (e) drying the deposited powder of metallic particles to further densify them; (f) repeating steps (a)-(e) on a reverse side of the dielectric material; and (g) repeating steps (a)-(f) until no unfilled vias are detected.
