Claim 6:
7. The method of fabricating the PCB assembly as in claim 1, wherein the one or more holes in the PCB substrate are formed in a first side of the PCB substrate by drilling or laser engraving the first side of the PCB substrate, but do not pass through an entire thickness of the PCB substrate, the layer of metal is formed in the one or more holes by LAD from the first side of the PCB substrate, the PCB substrate is subsequently flipped and the one or more holes are completed through the thickness of the PCB substrate by drilling or laser engraving through a second side of PCB substrate, and remaining portions of the one or more holes exposed by the drilling or laser engraving through the second side of PCB substrate are metalized by LAD.
