Embodiment Construction

[0031] The present invention will be further elaborated below with reference to the accompanying drawings.

[0032] In this embodiment, the glass fiber yarn used in the glass fiber cloth itself is twisted from hundreds of monofilaments, and in order to ensure the weaving efficiency and weaving quality, the surface of the warp yarn is also coated with a layer of size film before weaving to improve its weaving. Bundle. However, the woven glass fiber yarn remains in a bundled state, which is greatly hindered by the flatness, air permeability, and impregnation of the glass cloth. Therefore, the slurry on the surface of the glass fiber cloth needs to be removed. In addition, in order to improve the performance of the glass fiber cloth, the glass fiber cloth needs to be fiber-opened. The thinner the glass fiber cloth, the finer the fiber diameter of the glass fiber yarn used, and the more difficult the flat fiber opening technology is. Blindly increasing the fiber opening strength ...

Abstract

The invention discloses an after-treatment processing method and equipment of flat electronic grade glass fiber cloth. The method comprises the following steps: firstly, soaking and rinsing unwashed electronic grade glass fiber cloth with hot water to enable surface sizing agents to swell until the sizing agents are washed out of the surface of the electronic grade glass fiber cloth; then carrying out spunlacing and splitting treatment on the soaked and rinsed electronic grade glass fiber cloth. According to the after-treatment processing method and equipment of flat electronic grade glass fiber cloth, cloth cover yarns of the treated glass fiber cloth are minimally destroyed, the finally obtained electronic grade glass fiber cloth is thin in thickness, and low and uniform in air permeability, the flatness of the finally obtained electronic grade glass fiber cloth is better than the electronic grade glass fiber cloth treated by a common after-treatment technology.

Description

technical field [0001] The invention relates to the technical field of glass fiber cloth production, in particular to a post-processing method and equipment for flat electronic grade glass fiber cloth. Background technique [0002] Electronic grade glass fiber cloth, copper clad laminate and printed circuit board are three closely connected upstream and downstream industries in the same industrial chain. With the development of electronic terminal products and chip packaging technology, printed circuit board (PCB) substrates are becoming thinner, multi-layered, and denser. CCL) puts forward thinning requirements. For this reason, the thinning of copper clad laminates also puts forward new requirements for corresponding thinning of its main raw material, electronic cloth. Moreover, higher requirements are put forward for the resin impregnation, water inhibition and surface smoothness of electronic glass fiber cloth. [0003] The electronic grade glass fiber cloth industry ...
