INDUSTRIAL APPLICATION FIELD The present invention relates to an insulating sheet in which a glass fiber base material is impregnated with an epoxy resin-based synthetic resin. Conventional Structures and Problems Glass cloth-based epoxy resin laminates are used as wiring substrate materials for industrial electronic devices such as electronic computers. This type of laminate formation process involves, for example, coating a glass cloth base material with an epoxy resin compound composition and impregnating it, and finally heating and press-forming it to form a uniform thickness. Finished as a board or laminate. In this case, a brominated bisphenol epoxy resin is generally used to satisfy the flame retardancy of the laminate.
Adhesion to glass is not necessarily good. In addition, circuit wiring boards can be manufactured through, for example, a solder remelting process at around 240°C, a solder bath immersion process at around 260°C, or a solder remelting process at around 300°C, and a fine metal wire connection process at 240 to 300°C. Since it goes through several heating processes such as the so-called wire bonding process, it is required to have high thermal resistance. This thermal resistance is required to be even more severe in the case of single-sided wiring boards, double-sided wiring boards that are connected through through holes, insulating boards, and multilayer boards that are connected through through holes. Furthermore, in addition to electrical insulation, this type of circuit wiring board must also be suitable for mechanical opening processing such as through-hole formation, and is also resistant to vibration and mechanical pressure, such as peeling of laminated layers. , it is also a requirement that there is little deformation. In particular, when the glass fibers are opened by mechanical processing or subjected to thermal treatment, the bond between the glass fiber and the resin separates, and plating liquid, etching liquid, cleaning liquid, etc. are trapped in this area, resulting in a rapid decline in insulation properties. It may also be accompanied by problems such as short-circuit conditions. Purpose of the Invention The present invention solves the above-mentioned problems and provides a glass fiber-based epoxy resin sheet that has heat resistance, process resistance, and less deterioration after thermal and mechanical treatments. be. Structure of the invention The present invention includes an epoxy base material on a glass fiber base material,
This is a glass fiber-based epoxy resin sheet impregnated with an epoxy resin containing an aromatic amine adduct and a phosphionium salt in an equal weight ratio to the epoxy base resin, which provides insulation with excellent heat resistance and process resistance. A sheet is realized. The epoxy resins used in the present invention include bisphenol A type epoxy base resin (manufactured by Ciel Chemical Co., trade name Epicote 828), brominated epoxy base resin (manufactured by Ciel Chemical Co., trade name Epicote 828), brominated epoxy base resin (manufactured by Ciel Chemical Co., trade name Epicote 828)
1045) etc. The aromatic amine adduct used as a curing agent is tetrophenylolethane diamide (manufactured by Nippon Gosei Kako Co., Ltd., trade name H-84).
A quaternary phosphionium salt was used as a curing accelerator. Description of Examples Next, the present invention will be explained in detail with reference to Examples. The drawing is a schematic cross-sectional view of a printed wiring board according to an embodiment of the present invention, in which a 0.1 mm thick alkali-free glass cloth is impregnated with an epoxy resin formulated in the following embodiment to form a single sheet. An insulating substrate 1 is obtained by laminating six sheets of the same, and copper foil 2 with a thickness of 35 μm is laminated on both sides of this insulating substrate 1. The laminate was formed by dissolving the epoxy resin blended in the example in a B-stage state with a mixture of methyl ethyl ketone and methyl cellosolve to form a varnish, and impregnating the glass cloth with this. Afterwards, they were dried at 120°C for 5 minutes, and then heated with the copper foil at a contact pressure of 5Kg/cm 2 and a final pressure of 40Kg/cm 2 .

[Table] In the present invention, the phosphonium salt is not limited to quaternary phosphonium salts, and primary to tertiary phosphonium salts can be used, but empirically,
The quaternary phosphionium salt showed the best properties. Effects of the Invention According to the present invention, as a result of PCT, it exhibits outstanding performance, and as a glass fiber-based epoxy resin sheet, it is most suitable for printed wiring boards, and quality stability is guaranteed. Furthermore, according to the present invention, there is no need for a coupling agent, which was conventionally added to improve compatibility with the resin when forming a glass-based epoxy resin sheet, and the aromatic amine adduct of the hardening agent fully fulfills its role. It has been confirmed that this product is effective in preventing the contamination of impurities. In addition, if the number of resin sheets is limited to one or two, it is also possible to realize a flexible resin sheet.
