Abstract

A method and apparatus is disclosed for curing metal particles into continuous metal conductors on a nonconducting substrate. The apparatus includes a generator for supplying radio frequency energy through an impedance matching circuit to a coil positioned proximate to the substrate. The coil and substrate are placed in a chamber which is evacuated prior to curing and then pressurized with nitrogen gas. The electromagnetic flux lines generate eddy currents in the particles which heat them until at least some melt, thereby converting the metal particles into continuous conductors.
