The glass fiber electronic yarn is formed by twisting continuous glass strands, electronic cloth is formed by weaving, and the glass fiber electronic yarn is made into a Copper-Clad plate (Copper Clad Laminate) and then is used for electronic industrial products such as Printed Circuit boards (Printed Circuit boards) and the like. The raw materials for the copper-clad plate substrate mainly comprise a glass fiber cloth base, a paper base, a metal base and the like. The copper-clad plate is a basic material of a printed circuit board, and the printed circuit board is an important carrier of electronic communication equipment. The glass fiber electronic yarn is different from other industrial glass fiber spun yarns and is thinner than other glass fiber yarns, the diameter range of a single fiber is generally 3.5-9 mu m, and the fineness range of the glass fiber electronic yarn is 3.3-136 tex.
In recent years, electronic information communication technology has further developed with the development of industrial internet, new energy automobiles and the like, and thus, the demand for glass fiber electronic yarn and electronic cloth has been continuously increased. In order to achieve the purpose of higher speed and more reliable information transmission, the requirements on the printed circuit board and the copper-clad plate are higher, and the requirements on the glass fiber electronic cloth and the electronic yarn are also more rigorous. Currently, in order to meet the requirements of high-grade printed circuit boards, the thickness of electronic cloth needs to reach 0.03mm or less.
Although China is always in the largest glass fiber export state in the world, deep processing of the glass fiber electronic yarn industry is still urgent, and advanced product research and development and the highest manufacturing technology are mainly concentrated in countries such as Europe, America and Japan. The electronic cloth is divided into thick (more than 0.151mm), thin (0.15-0.051mm), ultra-thin (0.05-0.026mm) and ultra-thin (less than 0.025mm) according to the thickness. According to the standard, the higher level of the electronic cloth produced in China at present is 1067 cloth, the thickness of the electronic cloth is about 0.032mm, and the corresponding yarn fineness is 5.6 tex; and the electronic cloth woven abroad, especially Japan, reaches dozens of microns, such as 1037 (thickness 0.025mm), 1027 (thickness 0.020mm) and 1017 (thickness 0.015mm) cloth manufactured by Nidong textile company, and the fineness of the used glass fiber electronic yarn is as fine as 4.3tex, 3.3tex and 1.7 tex. Therefore, the superfine development of the glass fiber electronic yarn is a problem to be solved and overcome urgently in China.
