摘要:
A nonwoven fabric cloth substrate for printed wiring boards containing aromatic polyamide fibers and having a 0.7-1.0 dynamic elastic modulus ratio (E' (250.degree. C.)/E' (30.degree. C.)) and a 0.05 or less loss tangent (Tan.delta.) peak value at 30.degree.-250.degree. C., and a prepreg and a printed wiring board using the nonwoven fabric cloth substrate.
