Beschreibung
Zusammenfassung:	Disclosed herein are a printed circuit board and a method of manufacturing the same. The printed circuit board includes: a base substrate having a via hole for signal transfer and a via hole for heat radiation formed therein and having circuit layers formed on both surfaces thereof, the circuit layers including connection pads; a signal via formed in an inner portion of the via hole for signal transfer by performing a plating process using a conductive metal; and a heat radiation via formed in an inner portion of the via hole for heat radiation by performing a plating process using a conductive metal, wherein the heat radiation via is formed to have a diameter larger than that of the signal via.
