This invention discloses a high-toughness, low-dielectric bismaleimide resin composition, a modified bismaleimide resin, its preparation method, and its applications. The bismaleimide resin composition comprises bismaleimide resin, an allyl compound, and a liquid rubber, wherein the liquid rubber contains end-capping groups capable of reacting with double bonds. This invention primarily addresses the problems of high dielectric constant, poor toughness, and poor interlaminar shear strength in existing bismaleimide resins. In this invention, the dielectric properties and toughness are improved by reacting the end-capping groups in the liquid rubber with the bismaleimide resin, while maintaining the mechanical properties and heat resistance essentially unchanged.

The utility model relates to the field of electronic components, and particularly discloses a single buffer S-shaped stacked fisheye terminal which comprises a substrate, a first fisheye and a second fisheye, the first fisheye and the second fisheye are arranged at the two ends of the same side of the substrate, the substrate is folded to enable the first fisheye and the second fisheye to be overlapped to form a fisheye body, and the fisheye body is arranged on the substrate. A base used for buffering and supporting is arranged at the end, away from the fisheye body, of the base plate. The first fisheye and the second fisheye are arranged on the substrate, and the substrate is folded to enable the first fisheye and the second fisheye to be overlapped to form the fisheye structure, so that the overall structural strength is higher, the toughness is better, and bending is not prone to occurring; and the base is arranged on the substrate, and the whole body is supported and buffered through the base, so that the terminal can be effectively prevented from bending and losing efficacy.
