LAMINATED BOARD FOR PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a laminated board for a printed wiring board suitable for high-speed communication. SOLUTION: The laminated board for the printed wiring board includes a reinforcing fiber base material formed of melting anisotropic polyester amide fiber which is composed of aromatic polyester amide in which a portion formed of a plurality of repetitive constitutive units is 90 mol% or more and each of the repetitive constitutive units has a molar ratio of 100:1-20:5-100:2-80:2-20, and which has a strength (T150) in a 150°C atmosphere being 17 cN/dtex or more and an elastic modulus (E150) in the 150°C atmosphere being 710 cN/dtex or more.
