20100044087PREPREG, PRINTED WIRING BOARD, MULTILAYER CIRCUIT BOARD, AND PROCESS FOR MANUFACTURING PRINTED WIRING BOARD - The invention relates to a prepreg, obtained by impregnating a base material with an epoxy resin composition containing an epoxy resin(A), a curing agent (B), an accelerator (C), a phenoxy resin (D), and an inorganic filler (E) and semi-hardening the impregnated material, wherein the inorganic filler (E) has an average particle diameter of 3 μm or less. When a circuit with a narrow wire distance is formed on a surface of a insulator substrate composed of such a prepreg by using a method of forming the circuit by plating process, an amount of the plating remaining on the insulator substrate surface at the circuit contour periphery can be reduced. As a result, it leads to stabilization of inter-circuit insulation resistance and increase in a yield during production of printed wiring boards.02-25-2010
20100218982EPOXY RESIN COMPOSITION, PREPREG USING THE EPOXY RESIN COMPOSITION, METAL-CLAD LAMINATE, AND PRINTED WIRING BOARD - It is an object of the present invention to provide an epoxy resin composition containing an epoxy compound, a low-molecular-weight phenol-modified polyphenylene ether and a cyanate compound as essential components, the epoxy resin composition having excellent dielectric characteristics and exhibiting high heat resistance while maintaining flame retardancy. To achieve this object, the epoxy resin composition of the present invention is a thermosetting resin composition composed of a resin varnish containing (A) an epoxy compound having a number-average molecular weight of 1000 or less and containing at least two epoxy groups in the molecule without containing any halogen atoms, (B) a polyphenylene ether having a number-average molecular weight of 5000 or less, (C) a cyanate ester compound, (D) a curing catalyst and (E) a halogen flame retardant, wherein all of the components (A) to (C) are dissolved in the resin varnish, while the component (E) is dispersed without being dissolved in the resin varnish.09-02-2010
