Abstract: A circuit board structure includes a dielectric substrate, at least one embedded block, at least one electronic component, at least one first build-up circuit layer, at least one second build-up circuit layer, at least one conductive through hole, and a fine redistribution layer (RDL). The embedded block is fixed in a through cavity of the dielectric substrate. The electronic component is disposed in an opening of the embedded block. The first build-up circuit layer is disposed on a top surface of the dielectric substrate and electrically connected with the electronic component. The second build-up circuit layer is disposed on a bottom surface of the dielectric substrate and covers the embedded block. The conductive through hole is disposed in a via of the embedded block and electrically connects the first and the second build-up circuit layers. The fine RDL is disposed on and electrically connected to the first build-up circuit layer.
