Publication number: 20080070012Abstract: A carrier board has a copper substrate, an insulating layer, a copper layer, multiple recesses and a metal circuit layer. The substrate has at least one through hole. The insulating layer is a layer of glue that is insulating, acid-resisting and high-temperature-resisting and is mounted in the at least one through hole and mounted on the substrate. The copper layer is mounted on the insulating layer. The recesses are formed in the copper layer and the insulating layer that is mounted on the substrate. The metal circuit layer is plated on copper layer and along the recesses to contact with the substrate.
