Polyimide film and electric/electronic equipment bases with the use thereof |
摘要 |
A polyimide film having sufficiently excellent characteristics such as a sufficiently high elastic modulus, a low water absorption, a small coefficient of moisture-absorption expansion, a small coefficient of linear expansion and a high dimensional stability; and various electric/electronic equipment bases with the use of the polyimide film.A polyimide film having a tensile elastic modulus of 700 kg/mm2 or less and a coefficient of moisture-absorption expansion of 20 ppm or less and containing a specific repeating unit as an essential repeating unit is synthesized. Then various electric/electronic equipment bases such as a laminate for flexible print connection boards are produced by using the polyimide film.
