ABSTRACT:
Metallized through-holes are provided in insulating substrates by placing the substrate onto an absorbant carrier and screening a metallization paste, which contains a metal component dispersed in an organic solvent, into the holes. The carrier absorbs the solvent and a portion of the paste adheres to the carrier. When the carrier is stripped from the substrate it carries with it the center portion of the paste to leave a thin layer of paste on the inner surface of the substrate.
