Title:
フレキシブル積層板の製造方法
Document Type and Number:
Japanese Patent JP4593509
Kind Code:
B2
Abstract:
Provided is a manufacturing method of flexible laminated plate, wherein a required processing time of a heating step after dispensing a polyimide precursor resin solution on a conductive metal foil is short, so as to provide a flexible laminated plate having a low extension elasticity modulus, an excellent flexibility, and an excellent dimension stability. According to the manufacturing method of flexible laminated plate of the present invention, a polyimide precursor resin solution is dispensed on a conductive metal foil, and the polyimide precursor resin solution is then dried and cured by a heating processing, wherein, a total heating time of not less than 90 DEG C; in the heating processing is in a range of 5-25 minutes; the ratio of a heating time of 90-200 DEG C; to a heating time of more than 200 DEG C is set to be 9:1-7:3; the extension elasticity modulus of the polyimide resin layer formed on the conductive metal foil is controlled to be 3-6 Gpa,and the coefficient of heat expansion is controlled to be in a range of 16-28 ppm/DEG C.
