Embodiment Construction

[0033] The embodiments of the present invention are described in detail below: the present embodiment is implemented under the premise of the technical solution of the present invention, and detailed implementation and specific operation process are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0034] Table 1-1 Formula table of silane coupling agent treatment agent (each component by mass percentage)

[0035]

[0036] Table 1-1 Use the 1506 desizing cloth produced by our company (with a thickness of 0.14mm±0.24 and above), and use the treatment agent formula in Table 1-1 for treatment. The specific production process is as follows figure 1 shown. Embodiment 1 uses the pretreatment process of 0.10% silane coupling agent and 0.10% acetic acid and the balance is pure water for spraying. Comparative Example 1 did not carry out the pretreatment process.

Abstract

An electronic grade glass fiber cloth surface treating agent and a method relate to surface treatment technology of insulation reinforced material electronic grade glass fibre cloth applied to printed circuit boards. The method comprises that: desized electronic grade glass fibre cloth subjected to two-time desizing is sent for pretreatment, specifically a silane coupling agent pretreatment fluid with a weight percent of 0.03%-0.1% is employed for spraying processing on the cloth surface, and then the electronic grade glass fibre cloth enters an immersion trough for immersion processing by the silicane coupling agent treating agent provided by the invention. The formula of the silane coupling agent treating agent comprises: 0.03%-0.50% by weight of the silane coupling agent (with a general formula Y(CH2)nSiX3), 0.1%-1.7% of acetic acid, and the balance deionized water. The electronic grade glass fiber cloth surface treating agent is economical and efficient; and the electronic grade glass fiber cloth, which is produced by combining the electronic grade glass fiber cloth surface treating agent and the pretreatment technology, possesses the advantages of high heat resistance, ion migration resistance, relatively fast resin wetability and the like.

Description

technical field [0001] The invention relates to a surface treatment technology of electronic-grade glass fiber cloth, an insulation reinforcing material applied to printed circuit boards, in particular to a surface treatment agent for electronic-grade glass fiber cloth and electronic-grade glass fiber cloth produced by using the treatment agent. Background technique [0002] The electronic-grade glass fiber cloth used as the insulation reinforcement support of the printed circuit board is an alkali-free glass fiber (E-glass) material, and its main component is SiO 2 、Al 2 o 3 , CaO ternary three-dimensional network system, its main raw materials are silica sand, limestone, boron oxide and so on. Alkali-free glass fiber material has excellent electrical properties, insulation, weather resistance, chemical corrosion resistance, expansion and contraction resistance, etc., so it is widely used in the printed circuit board industry, mainly for insulation enhancement, and impreg...
