One conventional way of providing a circuit pattern on a circuit board substrate is to blanket plate or vapor deposit or otherwise apply a metal layer to the surface of a dielectric material to form a circuit board. Following this, some type of subtractive process is used to remove the metal from the areas where circuit lines are not desired, leaving metal at the desired circuit lines or pattern with the regions where the metal has been removed acting as a dielectric between the circuit lines.
