Ultra-high-performance electronic glass fiber cloth production process

Abstract

The invention discloses an ultra-high-performance electronic glass fiber cloth production process which specifically includes the steps: A, slightly splitting electronic glass fiber cloth; B, drying the slightly split electronic glass fiber cloth; C, deeply splitting the dried electronic glass fiber cloth; and D, drying the deeply split electronic glass fiber cloth so that ultra-high-performance electronic glass fiber cloth is obtained. During slight splitting, cloth surfaces are humidified by a water-washing oscillating trough, so that warp and weft yarns are bulked, and fibers are loosened; and during deep splitting, purified water is sprayed from holes of nozzles to be directly jetted to the cloth surfaces, the front and the back of the glass fiber cloth are sprayed by water columns, the warp and weft yarns are broken apart after the cloth surfaces are subjected to impact pressure of the purified water columns, the compactness of the glass fiber cloth is greatly reduced, and gaps among the warp and weft yarns are mostly filled by loose single fibers to be smaller, so that the surfaces of the glass fiber cloth become dense and uniform, and the surfaces of the glass fiber cloth are smoother after splitting.

Description

Technical field: [0001] The present invention relates to electronic grade glass fiber cloth, especially a production process of ultra-high performance electronic grade glass fiber cloth, and furthermore, it is an electronic grade glass with small gap between warp and weft yarns, good uniformity, flatness and air permeability. The production process of 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 depends on the gap between warp and weft yarns and the uniformity of gauze, ...

AI Technical Summary

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 fiber produced in this way Cloth, poor in resin impregnation and surface chemical or physical treatment, glass fiber cloth is not smooth, so it can not meet the production requirements of high-precision and high-performance PCB boards when corresponding to the production of PCB boards, especially with the development of PCB technology The continuous development of the current glass fiber cloth can no longer meet the needs of high-performance electronic products
