Abstract
A wiring board includes a substrate which has multiple opening portions and one or more boundary portions separating the opening portions, multiple electronic devices positioned in the opening portions of the substrate, respectively, a conductive pattern formed on a surface of the boundary portion, and an insulation layer formed on the substrate and the conductive pattern on the boundary portion of the substrate such that the insulation layer covers the electronic devices in the opening portions of the substrate.
Claims20
A wiring board, comprising:
- a substrate having an opening structure extending through the substrate such that the opening structure comprises a plurality of opening portions and at least one boundary portion partitioning the opening portions arrayed and penetrating through the substrate;
- a through-hole conductor formed in the opening structure such that the through-hole conductor is penetrating through the boundary portion of the opening structure in the substrate;
- a plurality of electronic devices positioned in the opening structure such that the plurality of electronic devices is accommodated in the plurality of opening portions of the opening structure, respectively;
- a conductive pattern formed on a surface of the boundary portion;
- and
- an insulation layer formed on the substrate such that the insulation layer is covering the conductive pattern on the boundary portion and the plurality of electronic devices in the plurality of opening portions of the opening structure in the substrate,
- wherein the conductive pattern on the boundary portion has an opening portion formed in the conductive pattern on the boundary portion, and the through-hole conductor is formed in a position corresponding to the opening portion formed in the conductive pattern on the boundary portion such that the through-hole conductor and the conductive pattern on the boundary portion are electrically insulated from each other.
