Problems solved by technology

[0004] At present, the production and manufacturing methods of glass fiber cloth are basically through warping, sizing, warping, weaving, desizing, and surface coupling agent treatment, and then the finished electronic grade glass fiber cloth is obtained. Electronic grade glass produced in this way Fiber cloth is poor in resin penetration and the glass fiber cloth is not smooth when the surface is chemically or physically treated. Therefore, it is impossible to meet the production requirements of high-precision and high-performance PCB boards when corresponding to the production of PCB boards. At the same time, the existing The PCB substrate material prepared by advanced technology-glass fiber cloth has poor heat resistance and high thermal expansion coefficient, especially with the continuous development of PCB technology, the current glass fiber cloth can no longer fully meet the needs of high-performance electronic products

Abstract

The invention belongs to the technical field of glass fiber cloth, and particularly relates to a preparation process of high-performance electronic-grade glass fiber cloth. The preparation process comprises the following steps: S1, carrying out light splitting treatment on desized glass fiber cloth; S2, drying, and then carrying out silane surface treatment; S3, carrying out deep splitting treatment; and S4, drying and shaping to obtain a high-performance electronic-grade glass fiber cloth finished product. According to the preparation process, the superficial area of warp yarn and weft yarn forming the glass fiber cloth is increased, methoxy groups of silane are combined with various inorganic substances in the presence of pure water, amino groups and reactive double bonds of silane can freely react with the inorganic substances and organic substances, the hydrolytic property of silane is enhanced in the reaction, and the impregnation of a coupling agent is more uniform, so that the impregnation property of resin is better, the bonding affinity with the resin is better, the glass fiber and the resin are combined more tightly, the heat resistance is greatly improved, and the stability of the PCB substrate is improved.

Description

technical field [0001] The invention belongs to the technical field of glass fiber cloth, and in particular relates to a preparation process of high-performance electronic grade glass fiber cloth. Background technique [0002] With the rapid development of electronic technology, people have higher and higher requirements for the performance of electronic products, and the PCB board that determines the performance of electronic products has correspondingly put forward higher requirements. [0003] Electronic-grade glass fiber cloth is an important raw material for manufacturing PCB boards. The performance of electronic-grade glass fiber cloth determines the quality of PCB boards. The performance of electronic-grade glass fiber cloth is closely related to the gap between warp and weft yarns and the uniformity of gauze, Flatness is related to air permeability. The smaller the gap between warp and weft yarns, the more uniform and smoother the gauze is. The lower the air permeabi...
