Surface treating agent for electronic-grade glass cloth and electronic-grade glass cloth surface produced by using the same

Abstract

The invention relates to a surface treating agent applied to the technical field of the electronic-grade glass fiber cloth and an electronic-grade glass fiber cloth produced by using the surface treating agent. The surface treating agent comprises the following ingredients in weight percentage: 0.2 to 0.8% of silane coupling agent having general formula of (Y(CH2)nSiX3), 0.3 to 1.0% of acetic acid, 0.05 to 0.1% of surfactant I, 0.02 to 0.05% of surfactant II, and the balance of de-ionized water. The invention is applicable to the surface treating technology of the electronic-grade glass fiber cloth of the high-precision, high-uniformity and high performance printing circuit board; the electronic-grade glass cloth processed by the surface treating agent and the surface treating process has the advantages of thinness, homogenization and faster resin soakage and is suitable for the insulation reinforcing material of the printing circuit board; furthermore, the invention can be widely applied to the high-end products including mobile phone boards, notebook computers, navigation, automobiles, servers and the like.

Description

technical field [0001] The invention relates to a surface treatment technology applied to electronic-grade glass fiber cloth for insulation reinforcement materials of printed circuit boards, in particular to an electronic-grade glass fiber surface treatment agent and electronic-grade glass fiber cloth produced by using the treatment agent. Background technique [0002] Electronic-grade glass fiber cloth used as insulation reinforcement for printed circuit boards is an inorganic material, specifically an alkali-free glass fiber (E-glass) material whose main component is SiO 2 、Al 2 o 3 , CaO ternary system, its main raw materials are silica sand, limestone, boron oxide, etc. Alkali-free glass fiber material has excellent electrical properties, insulation, weather resistance, and chemical corrosion resistance. Therefore, it is widely used in the printed circuit board industry and used as an insulation reinforcement material. A series of treatments are required before the im...

Problems solved by technology

If the coating amount of the silane coupling agent on the surface of the electronic grade glass fiber cloth is uneven, or the silane coupling agent treatment solution cannot penetrate into the interweaving point of the glass fiber cloth and each single filament inside, it will directly affect The tight combination of glass fiber cloth and resin seriously affects the reliability of the formed board
