1. A method for producing a printed circuit board on a substrate comprising:
a) printing a predetermined circuit pattern defined by connection traces onto the substrate using a conductive material;
b) applying additional connection traces onto the substrate;
c) depositing a metal layer onto the predetermined circuit pattern;
d) applying an insulation layer over the metal layer deposited onto the predetermined circuit pattern, thereby encapsulating and securing the metal layer; and
e) optionally removing any undesired connection traces from the predetermined circuit pattern.
