Abstract

The invention discloses a high-frequency high-speed copper clad laminate and a preparation method thereof. The preparation method comprises the following steps: step S1, preparation of resin glue; step S2, pretreatment of reinforcing materials; step S3, preparation of prepreg; step S4, manufacture of copper clad laminate. The present invention modifies bisphenol A cyanate resin through furan resin and unsaturated polyester resin, and the resin-reinforced glass fiber high-frequency and high-speed copper-clad laminate prepared by it has the electrical properties and insulation properties of traditional copper-clad laminates, etc. In addition to basic performance, it also overcomes some shortcomings of traditional copper-clad laminates, such as poor strength and flammability; the high-frequency and high-speed copper-clad laminates prepared by the present invention have excellent dielectric properties and high glass transition temperature, excellent heat resistance and flame retardancy, which can meet the needs of making high-frequency and high-speed circuit boards.
