Problems solved by technology

[0004] However, when the above-mentioned resin system is used to prepare high-performance substrates for high-frequency and high-speed applications, in order to improve heat resistance, thermal expansion coefficient or flame retardancy, it is necessary to add bismaleimide resin, benzoxazine resin, etc. to the resin composition. Other components such as resin or phosphorus-containing flame retardant, so the dielectric constant of the final substrate material still cannot meet the requirements of high-frequency and high-speed substrates

Abstract

Compared with the existing resin composition, the resin composition provided by the invention has the advantages of higher glass transition temperature, high heat resistance, high toughness and favorable dielectric property; the invention also provides a prepreg, an insulating film, a metal foil-coated laminated board and a printed circuit board which are prepared by using the resin composition.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a resin composition, a prepreg, a laminate, and a printed circuit board prepared therefrom. Background technique [0002] With the upgrading of technology, the automotive market, smart phones and other consumer electronics markets have put forward new requirements for PCBs. In 2018, with the commercial launch of 5G, the requirements for the dielectric properties of PCB substrates are higher. High-frequency and high-speed copper-clad laminates are one of the indispensable electronic substrates in the 5G era. To put it simply, the PCB substrate material needs to have a lower dielectric constant and dielectric loss tangent to reduce signal delay, distortion and loss during high-speed transmission, as well as interference between signals. Therefore, it is desired to provide a thermosetting resin composition, and the printed circuit board made by using the thermosetting res...
