Resumen:
The document specifies requirements for properties of woven E-glass laminated sheet of a thickness of 0,05 mm up to 3,2 mm, of defined flammability (vertical burning test), copper-clad. The glass transition temperature is defined to be 150 °C minimum. The relative permittivity is e equal or less than 4.1 and dispassion factor is equal or less than 0.0120 at 1 GHz.
Diese Norm enthält Anforderungen für die Eigenschaften von kupferkaschierten mit E-Glasgewebe verstärkten Laminattafeln mit definierter Brennbarkeit (Brennprüfung mit vertikaler Prüflingslage) in Dicken von 0,05 mm bis 3,20 mm. Die Glasübergangstemperatur ist auf eine Temperatur von mindestens 150 °C festgelegt. Die Permittivitätszahl beträgt maximal 4,1, der Verlustfaktor maximal 0,012 bei einer Frquenz von 1 GHz.
