  • Patent number: 10047222
    Abstract: Provided is a resin composition, comprising epoxy resin, oxydianiline type benzoxazine resin, styrene-maleic anhydride resin and tetra-phenol resin. The resin composition may be baked for producing products such as prepregs, resin films, resin-coated coppers, laminates and printed circuit boards, which satisfy one or more or all of desirable properties such as higher dimensional stability after a reflow process, better thermal resistance after horizontal black oxide process, low dielectric constant, low dissipation factor, high thermal resistance and flame retardancy.
    Type: Grant

  • Publication number: 20160165714
    Abstract: A multi-layer printed circuit board comprises: a core comprising a core insulation layer and traces formed on two sides of the core insulation layer; a plurality of insulation layers sequentially formed at two sides of the core; and a plurality of trace layers respectively formed between two insulation layers and on the outmost insulation layers; wherein the core insulation layer contains a resin material different from that of the insulation layers, such that the core insulation layer has a warpage characteristic lower than that of the insulation layers.
