Abstract:
1. A method for manufacturing a wiring board sheet, comprising: placing a conductor circuit on a base for transcription and mounting or forming through printing an electric component on the conductor circuit; layering the base and conductor circuit on an external surface of a resin layer in the B-stage so that the conductor circuit and electric component are opposite to the external surface of the resin layer and the conductor circuit and electric component are buried in the resin layer; then releasing the base from the resin layer while permitting the conductor circuit to remain in the resin layer external surface such that the external surface of the resin layer and an exposed surface of the conductor circuit are in the same plane; then layering a protective film on the external surface of the resin layer and the exposed surface of the conductor circuit; then creating a through hole that penetrates the protective film, conductor circuit and resin layer; applying a conductive paste to an external side of the protective film to fill the through hole with the conductive paste; and then releasing the protective film from the resin layer so that the conductive paste protrudes outwardly from the through hole above the plane of the external surface of the resin layer and the exposed surface of the conductor circuit.
