Abstract: A circuit board includes an electrical insulator layer formed of a reinforcer sheet with density distribution in its in-plane direction, an electrical conductor filled in a plurality of inner via holes provided in the electrical insulator layer in its thickness direction, and a wiring layer connected to the electrical conductor. The inner via holes provided in a high-density portion of the reinforcer sheet are formed to have a smaller cross-section than the inner via holes provided in a low-density portion of the reinforcer sheet. In this manner, it is possible to provide a circuit board that can achieve a high-density wiring and an inner via connection resistance with less variation, when a base material including a reinforcer sheet with density distribution in its in-plane direction such as a glass-epoxy base material is used for an insulator layer.

Abstract: A warp-free laminate is produced by winding a first set of strands or filaments about a flat mandrel with a second set of strands being wound transverse to the first set. The two sets may be perpendicular to each other. The filaments are maintained under a controlled tension while being impregnated with a resin and during subsequent cure of the resin. In order to permit the formation of a warp-free product, the winding pattern is such that it forms a mirror image about a neutral axis or plane of symmetry. The winding pattern may be chosen to provide interstices in a predetermined pattern determining punching out or high speed drilling of hole openings for subsequent printed circuit applications.

Abstract: Die Erfindung bezieht sich auf Basismaterialien und Prepregs aus Epoxidharzglasfasergewebe zur Herstellung von Leiterplatten. Die Dimensionsstabilität von Basismaterial und Prepreg ist je nach Typ unterschiedlich. Diese Unterschiedlichkeit wird durch Temperprozesse über den Glasumwandlungspunkt und Vorhaltewerte bei den Druckwerkzeugen zu kompensieren versucht. Durch die Erfindung soll die Dimensionsstabilität derartiger Materialien verbessert werden. Durch die Verwendung von unidirektionalen Geweben, bei denene das Verhältnis der Glasstränge in Kett- und Schußrichtung oder umgekehrt größer 70:30 und/oder das Verhältnis der Garngewichte in Kett- und Schußrichtung oder umgekehrt größer 1,5:1 beträgt, und/oder als Webart Satinbindung realisiert wird, wird eine deutliche Verbesserung der Dimensionsstabilität bei nur geringfügig erhöhten Kosten erzielt.
