Abstract | A multi-layer printed circuit board produced by laminating a plurality of unit circuit sheets via prepreg resin sheets, the cured resin in said unit circuit sheet having a glass transition temperature Tg1, said prepreg resin sheets having been prepared by impregnating a reinforcing substrate with a resin composition which can be cured at a temperature equal to or lower than both the glass transition temperature of Tg, and that of T92 of the resin in the prepreg resin sheet after cured, and binding the laminated sheets with heating under pressure at a temperature equal to or lower than both the temperatures of Tg, and Tg2, has excellent dimensional stability, heat resistance and through-hole reliability. |
