Metal foil-clad laminate having surface smoothness |
摘要 |
A metal foil-clad laminate obtained by lamination molding a resin-impregnated substrate and a metal foil, wherein the resin-impregnated substrate contains from 5 to 30% by weight of at least one inorganic filler selected from the group consisting of calcined kaolin, spherical fused silica, non-swellable synthetic mica, and a glass fine powder, the filler having an average particle diameter of from 0.1 to 5 mu m and at least 90 wt % of the filler having a particle diameter of from 0.02 to 5 mu m, and the resin-impregnated substrate is used as at least a surface layer of the laminate or as a resin-impregnated substrate which adheres the metal foil, thereby providing a surface smooth metal foil-clad laminate having a diminished surface undulation attributable to the substrate.
