<p>PURPOSE:To provide a composite copper-clad laminated board which has the improved tracking-resistance, is not influenced by the area ratio of a copper foil and, further, has excellent characteristics. CONSTITUTION:Woven glass cloths impregnated with thermosetting resin are laminated on both sides of a nonwoven glass cloth impregnated with thermosetting resin to obtain a substrate. Macrocrystalline electrolytic copper foils are applied to one of or both of the surfaces of the substrate with tracking-resistant adhesive layers therebetween.</p> |
