Problems solved by technology

It does not point out that the resin composition can be used for copper-clad laminates and prepregs. Even if the resin composition is used to cure the copper-clad laminate, its dielectric properties (dielectric loss tangent Df) will be significantly deteriorated (the resin composition contains acryloyl-based silicone resins, and acryloyl-containing silicone resins are more polar), which cannot meet the needs of high-frequency signal transmission

Description

technical field [0001] The invention belongs to the technical field of copper-clad laminates, and relates to a thermosetting resin composition and a prepreg and a metal foil-clad laminate made of the same. Background technique [0002] In recent years, with the development of high-performance, high-functionality and networking of computers and information communication equipment, in order to transmit high-speed and process large-capacity information, the operating signal tends to be high-frequency, so the material of the circuit board is required. In particular, there is a rapid development in those electronic devices using broadband such as mobile communication devices. [0003] Among conventional printed circuit board materials, epoxy resins excellent in adhesive properties are widely used. However, epoxy resin circuit substrates generally have high dielectric constant and dielectric loss tangent (dielectric constant Dk is greater than 4, dielectric loss tangent Df is abo...
