Abstract
The invention discloses a wide dielectric constant polytertrafluoroethylene (PTFE) glass-fabric copper clad laminate, comprising a dielectric layer (1) and copper foils (2) which is arranged on two faces of the dielectric layer (1); the dielectric layer (1)is a wide dielectric constant no-alkali glass fabric covered by a mixed-liquid coating. The dielectric layer of the invention is the wide dielectric constant no-alkali glass fabric provided with the mixed-liquid coatings including the PTFE, ceramics and organic assistant materials so as to reduce loss tangent value of the medium and enlarge the dielectric constant of the copper clad laminate, and the dielectric constant can be enlarged to be between 2.25 and 10.2, and then the volume resistance, surface resistance and surface insulation resistance are all enlarged and the hole-metallization difficulty can be reduced so as to enhance the capability of the board. The mixed-liquid coatings can be from more than 1 layer to dozens of layers so as to meet the requirements of different users.
Description
Technical field
The present invention relates to a kind of wide-dielectric constant polytetrafluoroethylglass glass cloth coated copper foil plate.
Background technology
The dielectric layer of copper foil clad plate of polytetrafluoroethylglass glass cloth is the alkali-free glass cloth that has polytetrafluoroethylene at present, and its dielectric constant is 2.2,2.7, and the scope of dielectric constant is smaller, and sheet resistance is 1 * 10
4M Ω cm, volume resistance are 1 * 10
6M Ω cm, it is not enough to occur surface insulation resistance in the use, is prone to the energising grounding phenomenon, and the hole metallization difficulty is bigger, greatly reduces the serviceability of sheet material, and the external general microfibre that adopts strengthens, but its price comparison height.
Summary of the invention
The invention provides a kind of wide-dielectric constant polytetrafluoroethylglass glass cloth coated copper foil plate, it has not only enlarged the scope of dielectric constant, and has increased sheet resistance and volume resistance, and surface insulation resistance strengthens, and price is also lower simultaneously.
The present invention has adopted following technical scheme: a kind of wide-dielectric constant polytetrafluoroethylglass glass cloth coated copper foil plate, and it comprises dielectric layer and Copper Foil, and the two sides of dielectric layer is a Copper Foil, and described dielectric layer is the wide-dielectric constant alkali-free glass cloth that is coated with the mixed liquor coating.Described mixed liquor coating comprises polyflon, pottery and organic auxiliary material.
Mainly comprise poly tetrafluoroethylene, ceramic powder in described organic auxiliary material.Which floor described mixed liquor coating arrive tens layers for.The mass ratio of described Copper Foil and dielectric layer is 1: 9.
Dielectric layer of the present invention is the wide-dielectric constant alkali-free glass cloth that has polyflon, pottery and some organic auxiliary material mixed liquor coatings, so not only can reduce the loss tangent of medium, enlarge the dielectric constant of copper foil plate, dielectric constant is expanded as between 2.25～10.2, volume resistance value, sheet resistance value and surface insulation resistance have been increased, the hole metallization difficulty reduces, thereby has strengthened the serviceability of plate.The mixed liquor coating can arrive tens layers for which floor, and it can satisfy different user's requests.
