Abstract

Disclosed is a heat dissipating circuit board, which includes a metal core including an insulating layer formed on the surface thereof, a circuit layer formed on the insulating layer and including a seed layer and a first circuit pattern, and a heat dissipating frame layer bonded onto the circuit layer using solder and having a second circuit pattern, and in which the heat dissipating frame layer is bonded onto the circuit layer not by a plating process but by using solder, thus reducing the cost and time of the plating process and relieving stress applied to the heat dissipating circuit board due to the plating process. A method of manufacturing the heat dissipating circuit board is also provided.
