  • Publication number: 20220217842
    Abstract: A printed circuit board includes a first insulating layer, a metal layer disposed on one surface of the first insulating layer, a first circuit layer disposed inside the first insulating layer and having one surface exposed to the one surface of the first insulating layer so as to be in contact with one surface of the metal layer, a second circuit layer in contact with the other surface of the metal layer, and a second insulating layer disposed on the one surface of the first insulating layer to cover the metal layer and the second circuit layer. The first and second circuit layers respectively include a metal different from the metal layer.
