Abstract: A method of fabricating a printed circuit board is disclosed. A method of fabricating a printed circuit board that includes: stacking an insulation layer on at least one surface of a core layer, on which an inner circuit is formed, and forming an outer circuit pattern; burying the outer circuit pattern in the insulation layer; removing the outer circuit pattern to form minute grooves and curing the insulation layer; and forming an outer circuit by filling metal in the minute grooves, makes it possible to readily form high-resolution fine-line circuits, as well as to reduce fabrication costs and increase productivity.
