Abstract
A resin composition and a metal clad substrate are provided. The resin composition includes: 5 phr to 15 phr of a maleimide resin, 5 phr to 30 phr of a benzoxazine resin, 40 phr to 70 phr of an epoxy resin, and 40 phr to 60 phr of fillers. An amount of fluorine atoms contained in the maleimide resin ranges from 10 wt % to 50 wt %.
Claims10
A resin composition, comprising:
- 5 to 15 parts by weight of a maleimide resin, wherein an amount of fluorine atoms contained in the maleimide resin ranges from 10 wt % to 50 wt %;
- 5 to 30 parts by weight of a benzoxazine resin;
- 40 to 70 parts by weight of an epoxy resin;
