Abstract

PURPOSE: To make a disposable aluminum intermediate plate usable and to make maintenance cost inexpensive by successively laminating a copper foil layer to be set to the outermost layer, an intermediate base material layer impregnated with a resin low in a softening degree at high temp. and a base material layer impregnated with a usual resin and molding all of them under heating and pressure.
CONSTITUTION: A copper foil layer 1, an intermediate base material layer 2 impregnated with a resin low in a softening degree at high temp. and a base material layer 3 impregnated with a usual resin are successively laminated. As the resin used in the base material layer 2, a thermoplastic resin such as a polyimide resin is used but a resin having an especially high softening point is selected. The base material layer 3 impregnated with a usual resin is formed using the same inorg. fiber material as the base material layer 2. Both surfaces of a four-layer plate 8 wherein the single-sided copper clad laminated sheets 4 thus formed are superposed on both surfaces of an inner layer circuit board 5 through the usual resin impregnated base material layers 3 are sandwiched between disposable aluminum plates 7 to be piled up and molded under heating and pressure to obtain a multilayer printed wiring board. Since the resin softening degree at the time of pressing is low, no unevenness is generat ed even when the soft aluminum plate is used and the circuit of the inner layer circuit board 5 is not transferred to the multilayer printed wiring board.
