Abstract

The invention discloses a polytetrafluoroethylene alkali-free plain weave glass cloth-covered plane resistance copper foil laminate, which is mainly composed of a dielectric layer, a resistance copper foil layer and a roughened copper foil layer. The upper side of the dielectric layer is provided with a resistor As for the copper foil layer, a roughened copper foil layer is provided on the lower side of the dielectric layer. The invention has low dielectric, low loss, excellent electrical and mechanical properties, low thermal coefficient of dielectric constant, low exhaust, and small equipment volume. The main body of the invention is non-alkali plain glass cloth, on which a film coating can be arranged, so that the performance of the product can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of resistance pressing plates, and in particular relates to a polytetrafluoroethylene alkali-free plain glass cloth-coated plane resistance copper foil laminate. Background technique [0002] The current PTFE glass cloth-clad planar resistance copper foil laminate is coated with roughened copper foil without resistance on both sides, which not only increases the volume of equipment, but also reduces its mechanical and electrical properties in the design of complex microwave structures. The stability is relatively poor. Contents of the invention [0003] The object of the present invention is to provide a polytetrafluoroethylene non-alkali plain weave glass cloth covered plane resistance copper foil laminate, which has solved the shortcomings in the above-mentioned solution. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] A polytetrafluoroe...
