Claim 0:
1. A method of fabricating a printed circuit board (PCB) assembly, comprising depositing a layer of metal on a PCB substrate by laser-assisted deposition (LAD) in which jetting of metal droplets from a first donor substrate onto the PCB substrate and/or into one or more holes therein is effected using a laser to form the layer of metal on the PCB substrate, the layer of metal being subsequently dried and sintered, with the jetting, drying, and sintering being repeated until the layer of metal reaches a desired thickness, and thereafter forming at least one passivation layer over the layer of metal by jetting an epoxy from a second donor substrate using the same laser that was used for forming the layer of metal on the PCB to form a layer of the epoxy.
