Background
The electronic glass fiber cloth is formed by weaving electronic grade glass fiber yarns, and then the finished product of the electronic grade glass fiber cloth is formed through the steps of desizing, smoldering and adding a treating agent. The batch thin cloth commonly used in the market at present is 1080 cloth, the gram weight is 47.5 g/square meter, and the thickness is 0.050 mm. With the progress of science and technology, various electronic products are developed in the direction of light, small and thin. The corresponding copper-clad plate manufacturer needs an ultra-thin electronic grade glass fiber cloth.
The following technical difficulties need to be overcome in the production process of the thin cloth: the yarn for the thin cloth is thin, and the tension of a warp beam is difficult to control uniformly in the sizing process, so that the tension of the cloth surface is uneven, and the finished cloth has an abnormal condition of uneven cloth surface. Secondly, the control of temperature and time in the desizing process is not easy to master, and the desizing is not thorough at low temperature, so that the PP slices have bad fish eyes and are degraded; when the temperature is high and the time is long, the thin cloth is burnt thoroughly due to the thin cloth, and the conditions of tearing and strength failure are generated. Thirdly, the weaving process of selecting a cloth thinner than 1080 cloth is difficult, and proper yarn types and proper combination of warp and weft density can be selected.
There is a need for an ultra-thin electronic grade glass fiber cloth to meet the requirements of downstream customers and meet the market demand.
