20140349090 | LOW DIELECTRIC HALOGEN-FREE RESIN COMPOSITION AND CIRCUIT BOARD USING THE SAME - A halogen-free resin composition includes (A) 100 parts by weight of polyphenylene oxide resin; (B) 10 to 50 parts by weight of maleimide resin; (C) 5 to 100 parts by weight of polybutadiene copolymer; (D) 5 to 30 parts by weight of cyanate ester resin; and (E) 15 to 150 parts by weight of phosphazene. The halogen-free resin composition is characterized by specific ingredients and proportions thereof to achieve circuit board laminate properties, such as a high glass transition temperature, low coefficient of thermal expansion, low dielectric properties, heat resistance, flame retardation, and being halogen-free, and thus is applicable to the manufacturing of a prepreg or resin film, thereby being applicable to the manufacturing of metal laminates and printed circuit boards. | 11-27-2014 |
20140178696 | RESIN COMPOSITION, COPPER-CLAD LAMINATE AND PRINTED CIRCUIT BOARD FOR USE THEREWITH - A resin composition includes (A) an epoxy resin; (B) a benzoxazine (BZ) resin; (C) a styrene maleic anhydride (SMA) copolymer; and (D) a polyester. The resin composition includes specific ingredients of a polyester and is characterized by specific proportions thereof so as to achieve a low delta Tg value of copper clad laminates manufactured in accordance with the resin composition and attain a low dielectric constant, a low dielectric dissipation factor, high heat resistance, and high fire retardation of the copper clad laminates and printed circuit boards manufactured in accordance with the resin composition. | 06-26-2014 |
20130245161 | RESIN COMPOSITION FOR INSULATION FILM - A resin composition includes (A) 100 parts by weight of epoxy resin; (B) 20 to 100 parts by weight of polybutadiene styrene divinylbenzene graft terpolymer resin; (C) 2 to 20 parts by weight of di-tert-butylhydroquinone (DTBHQ); (D) 5 to 50 parts by weight of polyphenyl ether modified cyanate ester resin; and at least one of (E) inorganic filler, (F) chain extending sealing agent, and (G) catalyst. The resin composition is characterized by specific ingredients and proportions thereof to attain high heat resistance, low dielectric constant Dk, and low dielectric dissipation factor Df, and being halogen-free, and therefore is applicable to protective film of printed circuit boards, insulating protective film of electronic components, and resin insulation film of leadframes. | 09-19-2013 |
20130115472 | HALOGEN-FREE RESIN COMPOSITION, AND COPPER CLAD LAMINATE AND PRINTED CIRCUIT BOARD USING SAME - The halogen-free resin composition comprises (A) 100 parts by weight of cyanate ester resin; (B) 5 to 50 parts by weight of styrene-maleic anhydride; (C) 5 to 100 parts by weight of polyphenylene oxide resin; (D) 10 to 150 parts by weight of phosphazene; and (E) 10 to 1000 parts by weight of inorganic filler. By using specific components at specific proportions, the halogen-free resin composition offers the features of low dielectric constant, low dissipation factor, high heat resistance and high flame retardancy, and can be made into prepreg or resin film, and thereby used in copper clad laminate or printed circuit board. | 05-09-2013 |
