Abstract:
A method of manufacturing a printed circuit board (PCB) having embedded resistors, including providing a PCB on which internal layer circuit patterns, including electrode pads, are formed; layering insulating layers on the PCB; forming first via holes on the electrode pads and simultaneously forming second via holes at predetermined locations on the internal layer circuit patterns; forming contact pads for connecting the electrode pads with resistors by filling the first via holes with oxidation-resistant conductive material and flattening the oxidation-resistant conductive material; forming the resistors so that ends of each resistor are connected to two respective contact pads, which are spaced apart from each other; forming circuit patterns on the PCB, in which the second via holes are formed; and layering insulting layers on the PCB having the formed circuit patterns, and forming external layer circuit patterns.
