低ε_r、低tgδFR—4印刷电路基板的研制

【摘要】 本文采用氰酸酯改性环氧树脂体系 ,使之改性的环氧树脂体系介电性能提高 (低εr、低tgδ)。用此改性的树脂体系试制了高性能FR— 4印刷电路基板 ,性能测试结果表明 ,该印刷电路基板较通用FR— 4印刷电路基板介电性能优异以外 ,其它性能均达到了FR— 4同类制品的技术标准要求更多还原

【Abstract】 The dielectric properties of epoxy resin were improved by cyanate.we used the improved epoxy resin and developed FR-4 printed circuit board with lower ε r and tgδ.The resting results of properties showed that PB not only had better dielectric properties,but also had others good properties comparable to FR 4.更多还原
