Title:
低誘電基板材料及びそれを用いた金属基板
Document Type and Number:
Japanese Patent JP7457081
Kind Code:
B2
Abstract:
A low-dielectric substrate material and a metal substrate using the same are provided. The low-dielectric substrate material includes a rubber resin composition, at least one inorganic filler, and borosilicate-type hollow microparticles. The rubber resin composition includes 30 wt % to 60 wt % of a liquid rubber, 10 wt % to 40 wt % of a polyphenylene ether resin, and 10 wt % to 40 wt % of a crosslinker. A molecular weight of the liquid rubber ranges from 2500 g/mol to 6000 g/mol. The at least one inorganic filler is selected from the group consisting of magnesium oxide, aluminum oxide, silicon oxide, zinc oxide, aluminum nitride, boron nitride, silicon carbide, and aluminum silicate. An amount of the borosilicate-type hollow microparticles is not more than 10 phr relative to 100 phr of the rubber resin composition.
