Magnetic prepreg, its manufacturing method and printed wiring board employing the prepreg
摘要：
For improving a noise characteristic of a printed circuit board excellent in noise characteristic, a magnetic prepreg formed by impregnating a magnetic paint composed of soft magnetic powder and thermosetting resin into a glass cloth is used as a prepreg constituting the printed circuit board. It is preferable that the soft magnetic powder is metal powder being essentially flat. Further, it is preferable that a main component of the thermosetting resin is epoxy resin.
摘要（中）：

为了提高噪声特性优异的印刷电路板的噪声特性，使用将由软磁粉末和热固性树脂构成的磁性涂料浸渍在玻璃布中而形成的磁性预浸料作为构成印刷电路板的预浸料坯。 优选软磁性粉末是金属粉末基本上平坦的。 此外，热固性树脂的主要成分优选为环氧树脂。
