    摘要: The present invention has an object to provide a producing method and producing apparatus of multilayered printed-circuit board that has eliminated the resin flow and resolved the problems of board thickness discrepancy and misregistration.
    A producing method of multilayered printed-circuit board , comprising steps of stacking up a laminated sheet covered with conductive foil or conductor for outer layer, a prepreg and a laminated sheet covered with conductor for inner layer and, thereafter, setting the prepreg by pressurizing/heating, wherein, before conducting the pressurizing/heating, gas is sprayed to the surface of the laminated sheet covered with conductive foil or conductor for outer layer, a prepreg and a laminated sheet covered with conductor for inner layer to eliminate impurities from the surface.
