, Hey Gary! To take the definition revolving around printed components one step further: IMO if you are working with transmission lines, differential impedance, co-planar waveguide, picket fencing, low-noise or high-power considerations, embedded capacitance, buried resistance, or etched inductors then you are working with a printed circuit. Otherwise you are working with printed wiring, of which there is still plenty in the world.
