Patent ID: 8549744

Claim:
A method of manufacturing a printed circuit board using bumps, comprising: forming a through hole on a core board; filling the through hole by fill-plating and forming a circuit on the surface of the core board; joining a core bump on at least one surface of the position where the through hole is formed; setting the core bump; stacking an insulation material on the at least one surface of the core board such that the core bump penetrates the insulation material and stacking a conductive layer on the insulation material; and forming a circuit on the surface of the conductive layer, wherein the fill-plating is reverse pulse plating, and is performed on the insulation material having a thickness of 100-400 μm, included in the core board, and is performed at 1-10ASD of forward current density, 10-500 ms of forward time, 5-50 ASD of reverse current density, and 0.4-25 ms of reverse time.
