    • A manufacturing method of a multilayer printed wiring board in which a copper foil with carrier foil consists of at least four layers, a carrier foil/a release layer/a heat-resistant metal layer/a copper foil layer is used; a supporting substrate is manufactured by laminating an insulating layer constituting material on the surface of the copper foil layer constituting the copper foil with carrier foil; a supporting substrate with build-up wiring layer is manufactured by forming a build-up wiring layer on the surface of the carrier foil constituting the copper foil with carrier foil in the supporting substrate; the resulted supporting substrate with build-up wiring layer is separated at the release layer to manufacture a multilayered laminate; the resulted multilayered laminate is processed a necessary procedures to manufacture a multilayer printed wiring board.
    • 具有载体箔的铜箔由至少四层构成的多层印刷电路板的制造方法,使用载体箔/剥离层/耐热金属层/铜箔层; 通过在构成铜箔的铜箔层的表面上与载体箔层叠绝缘层构成材料来制造支撑基板; 通过在支撑基板上通过载体箔在构成铜箔的载体箔的表面上形成积层布线层来制造具有堆积布线层的支撑基板; 所得到的具有积层布线层的支撑基底在剥离层处分离以制造多层层压体; 对所得到的多层层压体进行处理以制造多层印刷线路板的必要程序。
