Abstract

The invention relates to an epoxy resin composition as well as prepreg, a laminated board and a printed circuit board, which use the epoxy resin composition. The epoxy resin composition provided by the invention is prepared from epoxy resin (A), a maleimide compound (B) with the structure of a formula (I) and an active ester compound (C). The prepreg, the laminated board (including a metallic foilclad laminated board) and the printed circuit board, which are made by using the epoxy resin composition, have the characteristics of being low in dielectric constant (Dk) / dielectric loss angle tangent value (Df), high in glass-transition temperature (Tg), low in water absorption, low in coefficient of thermal expansion (CTE) and excellent in heat resistance and heat and humidity resistance, andthe like.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to an epoxy resin composition and its prepreg, laminated board and printed circuit board. Background technique [0002] With the rapid development of the electronics industry, electronic products are developing toward lightness, thinness, shortness, high density, safety, and high functionality. Electronic components are required to have higher wiring density, high integration and reliability. Metal clad laminates for making printed circuit boards have more excellent heat and humidity resistance, low thermal expansion coefficient, dielectric constant and low water absorption. [0003] Epoxy resin has excellent mechanical properties and processability. It is a commonly used matrix resin in the production of metal foil-clad laminates for high-end printed circuit boards. The prepregs and laminates produced are widely used as a A modified raw material is used in high-perform...
