Electronic grade glass fiber cloth thin fabric

At present, the electronic grade glass fiber cloth thin fabrics on the market have unsatisfactory fiber opening effect. The warp and weft yarn width is small and the fiber opening uniformity is not good. During the weaving process of the electronic cloth, the warp yarn bears a tension of about 20Kg. This resistance must be overcome when opening the fiber. And friction, so the fiber opening effect is poor, the surface roughness of the prepreg produced by using this kind of cloth is large, the flatness is not good, the made substrate has poor resin wettability, and it is easy to have holes and drill holes between the glass fiber filaments. It has poor performance and poor ion migration resistance, and cannot meet the production requirements of high-end copper clad laminates.
