Apparatus and method for depositing metal particles on a dielectric substrate

摘要

A method and apparatus for making a template used in manufacturing printed circuit boards is disclosed. The template is made from boron nitride, silicon nitride or similar material which has a melting temperature higher than the melting temperature of the metal forming the conductors in the printed circuit board, is readily machinable or moldable with the desired circuit pattern, and does not adhere to the metal conductors after the metal particles have been melted onto the substrate.
