Abstract:
Disclosed herein is an electronic component-embedded printed circuit board, including: a metal substrate including an anodic oxide film formed over the entire surface thereof; two electronic components disposed in a cavity formed in the metal substrate in two stages; an insulation layer formed on both sides of the metal substrate to bury the electronic components disposed in the cavity; and circuit layers including vias connected with connecting terminals of the electronic components and formed on the exposed surfaces of the insulation layer. The electronic component-embedded printed circuit board is advantageous in that its radiation performance of radiating the heat generated from an electronic component can be improved, and its production cost can be reduced, because a metal substrate is used instead of a conventional insulating material.
