  • Patent number: 11930595
    Abstract: The present application provides a circuit material and a circuit board containing the same. The circuit material comprises a conductive metal layer and a dielectric substrate layer, and an adhesive layer arranged therebetween, wherein the adhesive layer is made of a material which comprises an adhesive composition comprising a resin component and a non-resin component, wherein the resin component is composed of unsaturated polyphenylene ether resin, SBS resin and maleimide resin; and the non-resin component comprises an initiator; and the adhesive layer is obtained by applying the adhesive composition dissolved in a solvent onto the surface of the conductive metal layer or the dielectric substrate layer in the form of a solution, or by applying to a release material and removing the release material after partially curing or completely curing.

  • Publication number: 20240010810
    Abstract: A magnetic dielectric resin composition, and a prepreg and a copper clad laminate comprising same. The magnetic dielectric resin composition comprises a resin and a magnetic filler. The absolute value of the temperature drift coefficient of the magnetic filler under the conditions of ?55° C. to 150° C. is 0-1000 ppm/° C. Preparation raw materials of the magnetic filler comprise a combination of iron oxide and a metal oxide. By means of mutual synergy of the resin and the specific magnetic filler, and on the premise of ensuring good dielectric properties, the magnetic dielectric resin composition has a high magnetic permeability, a low magnetic loss, and a proper cut-off frequency, and can also reduce a temperature drift coefficient and improve stability.

  • Patent number: 11584851
    Abstract: The present application provides a resin component, and a prepreg and a circuit material using the same. The resin component comprises unsaturated polyphenylene ether resin, polyolefin resin, terpene resin and an initiator. When the total weight of the unsaturated polyphenylene ether resin, polyolefin resin and terpene resin is defined as 100 parts by weight, the terpene resin is in an amount of 3-40 parts by weight. The polyolefin resin is one or a combination of at least two selected from the group consisting of unsaturated polybutadiene resin, SBS resin and styrene butadiene resin. The present application discloses that the resulting resin composition has good film-forming properties, adhesion and dielectric properties through the coordination of unsaturated polyphenylene ether resin, unsaturated polyphenylene ether resin, polyolefin resin and terpene resin, and the circuit boards using the same have higher interlayer peel strength and lower dielectric loss.
