Disclosed herein is a heat-radiating substrate. The heat-radiating substrate includes: a metal core layer; a first insulating layer that is formed on one side or both sides of the metal core layer, includes a bather layer contacting with the metal core layer, first and second pores having different diameters, and a porous layer connected with the bather layer; a first circuit layer that is embedded in the first insulating layer, filled in the second pores of the porous layer, and connected to the sides of the second pores; and a second insulating layer that is formed on the porous layer of the first insulating layer. Further, in the heat-radiating substrate of the present embodiment, the first circuit layer is partially filled in the second pores and the second insulating layer is filled in the second pores to make a plane the first insulating layer. In addition, disclosed is a method of manufacturing the heat-radiating substrate.

Heat-radiating substrate and manufacturing method thereof

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.

Heat dissipating circuit board and method of manufacturing the same

Disclosed is a rigid-flexible circuit board, which includes a rigid region and a flexible region, the rigid region including a flexible substrate having a first circuit layer on both surfaces thereof, a metal core substrate formed on the flexible substrate and having a second circuit layer on both surfaces thereof, and an adhesive layer disposed between the flexible substrate and the metal core substrate, wherein the metal core substrate includes a metal core having a through hole, and an insulating layer formed on a surface of the metal core, so that the rigid region and the flexible region are thermally separated from each other and heat dissipation properties of the rigid region are improved. A method of manufacturing the rigid-flexible circuit board is also provided.
