MULTILAYERED PRINTED WIRING BOARD AND ITS MANUFACTURE |
摘要 |
<p>It is to provide a multilayer printed circuit board having excellent resolution, interlaminar insulation property and resistance to cool-heat shock without forming unevenness on the surface and lowering peel strength even if the thickness of the resin insulating layer is thin. The invention proposes a multilayer printed circuit board comprising an upper conductor circuit layer, a lower conductor circuit layer and a resin insulating layer electrically insulating both the conductor circuit layers, in which the resin insulating layer is a composite layer comprised of an insulating layer made from a heat-resistant resin hardly soluble in acid or oxidizing agent as a lower layer and an adhesive layer for electroless plating made from a heat-resistant resin as an upper layer, and if necessary, a resin is filled in a concave portion created between conductor circuits of the lower layer so as to render the surface into the same plane as the surface of the conductor circuit. <IMAGE></p> |
