Abstract
The invention discloses a wide-dielectric-coefficient copper foil plate covered with wide-dielectric-coefficient polyfluortetraethylene glass cloth, comprising a dielectric layer. The dielectric layer is a polyfluortetraethylene film layer (1) the surface of which is covered with a copper foil layer (2). The invention also discloses a preparation method of the wide-dielectric-coefficient copper foil plate covered with the wide-dielectric-coefficient polyfluortetraethylene glass cloth. The preparation method comprises the following steps of: (1) preparing a polyfluortetraethylene film layer (1): impregnating alkali-free glass cloth in polyfluortetraethylene resin to prepare the polyfluortetraethylene film layer (1); and (2) coating a copper foil layerplate on the polyfluortetraethylene film layer (1) to prepare the wide-dielectric-coefficienta copper foil plate covered with wide-dielectric-coefficient the polyfluortetraethylene glass cloth. The invention can adjust the dielectric coefficient of the product through the impregnation degree of the alkali-free glass cloth and the polyfluortetraethylene of the polyfluortetraethylene dielectric layer and the mass proportion relation between the alkali-free glass cloth and the polyfluortetraethylene so that the dielectric coefficient reaches a number between 2.2 to 4.0, the preparation cost is lower, and the processing is simple.
Description
Technical field
The present invention relates to a kind of wide-dielectric constant polytetrafluoroethylglass glass cloth coated copper foil plate and preparation method thereof.
Background technology
The dielectric layer of copper foil clad plate of polytetrafluoroethylglass glass cloth has the alkali-free glass cloth of polyflon at present, its dielectric constant is 2.55,2.7, dielectric constant range is little, greatly reduce the serviceability and the range of application of sheet material, and wide-dielectric constant polytetrafluoroethylglass glass cloth coated copper foil plate is adding man-hour, add ceramic powder and widen dielectric constant, but cost is higher, difficulty of processing is big.
