Claim 11:
12. A method of fabricating of a printed circuit board (PCB) assembly, comprising printing, by laser assisted deposition (LAD) a metal onto an epoxy laminate, the metal being jetted as droplets from a metal coating or foil on a donor substrate by a laser into channels and/or holes created in the epoxy laminate by laser engraving, and subsequently attaching the epoxy laminate to a PCB substrate or a previously formed epoxy layer disposed over the PCB substrate by hot pressing to form at least a portion of the PCB assembly, with the metal jetted into the channels and/or holes of the epoxy laminate being between the PCB substrate and an upper surface of the epoxy laminate in the portion of the PCB assembly and the epoxy laminate forming a passivation layer over the metal.
