    Abstract: A bridged polysilsesquioxane-based flame retardant filler imparts flame retardancy to manufactured articles such as printed circuit boards (PCBs), connectors, and other articles of manufacture that employ thermosetting plastics or thermoplastics. In an exemplary synthetic method, a bridged polysilsesquioxane-based flame retardant filler is prepared by sol-gel polymerization of a monomer having two or more trialkoxysilyl groups attached to an organic bridging group that contains a fire retardant group (e.g., a halogen atom, a phosphinate, a phosphonate, a phosphate ester, and combinations thereof). Bridged polysilsesquioxane particles formed by sol-gel polymerization of (((2,5-dibromo-1,4-phenylene)bis(oxy))bis(ethane-2,1-diyl))bis(trimethoxysilane), for example, and follow-on sol-gel processing may serve both as a filler for rheology control (viscosity, flow, etc.) and a flame retardant. In an exemplary application, a PCB laminate stack-up includes conductive planes separated from each other by a dielectric material that includes a bridged polysilsesquioxane-based flame retardant filler.

    Abstract: A halogen-free resin composition includes (A) 100 parts by weight of epoxy resin; (B) 2 to 15 parts by weight of oxydianiline (ODA); and (C) 2 to 20 parts by weight of amino triazine novolac (ATN) resin. The halogen-free resin composition includes specific ingredients, and is characterized by specific proportions thereof, to thereby achieve a low dielectric constant, a low dielectric dissipation factor, high heat resistance, and high flame retardation, and thus is suitable for producing a prepreg or resin film to thereby be applicable to copper clad laminates and printed circuit boards.
