A circuit board includes an insulating made by a low dielectric resin composition includes a low dielectric resin containing acid anhydride, an epoxy resin, polyphenylene ether resin with vinyl and active esters, maleic acid liquid polybutadiene, and an accelerator. Such low dielectric resin can be dissolved in organic solvent more easily than a low dielectric resin without acid anhydride, and the low dielectric resin containing acid anhydride has a better compatibility with other organic components than a low dielectric resin without acid anhydride. A low dielectric resin composition with lower dielectric constant and better properties can thus be obtained.
一种电路板包括由低介电树脂组合物制成的绝缘层,低介电树脂组合物包括含酸酐的低介电树脂、环氧树脂、含乙烯基和活性酯的聚苯醚树脂、马来酸液态聚丁二烯和促进剂。与不含酸酐的低电介质树脂相比,这种低电介质树脂更容易溶解在有机溶剂中,与不含酸酐的低电介质树脂相比,含酸酐的低电介质树脂与其他有机成分的相容性更好。因此,可以获得介电常数更低、性能更好的低介电树脂组合物。
