Problems solved by technology

The treatment agent provided in this patent is an unstable solution system, which will change with time and pH value, and there will be a tendency for the particle size of the dispersed phase to grow, and stratification and precipitation will occur, resulting in fish eyes and white spots on the electronic cloth. Weaken the tensile strength of glass fiber, thus affecting the mechanical properties, electrical properties and processing properties of copper clad laminates

Abstract

The invention belongs to the technical field of electronic processing, and particularly relates to a production method of electronic-grade glass fiber cloth. Defoaming is performed in the process of glass fiber preparation, joint action of an impregnating agent and surface chemical treatment agent is utilized, parameters during preparation are adjusted reasonably, and a method of combining pretreatment with aftertreatment is adopted, so that the electronic-grade glass fiber cloth produced by the method has high tensile strength and wear resistance, and mechanical performance, electrical performance and processability of a copper-clad plate are improved.

Description

technical field [0001] The invention belongs to the technical field of electronic processing, and in particular relates to a production method of electronic grade glass fiber cloth. Background technique [0002] Electronic grade glass fiber yarn and cloth (hereinafter referred to as "electronic yarn and electronic cloth") is one of the electrical insulating glass fiber series products, and is an indispensable and irreplaceable basic material for copper clad laminates and printed circuit boards. [0003] After the electronic cloth is finished by air-jet weaving, it enters the surface treatment process. This is the last process in the electronic cloth production process. The processing quality of electronic cloth in this process will directly determine the quality of the final product of electronic cloth. The quality of the electronic cloth is also an important key to the appearance quality of the copper clad laminate and the processing performance and physical and chemical ...
