a polyimide metal laminated plate has a first metallic film , a first thermoplastic polyimide film laminated on a surface of the first metallic film , a first thermosetting polyimide film laminated on a surface of the first thermoplastic polyimide film distal from the first metallic film , and a second thermoplastic polyimide film laminated on a surface of the first thermosetting polyimide film distal from the first thermoplastic polyimide film . the polyimide metal laminated plate has no adhesive layer , so the polyimide metal laminated plate not only has good heat resistance , flame resistance , anti - chemical properties , and dimensional stability , but also meets the thinning tendency of fpcb . in addition , by the first thermosetting polyimide film and the second thermoplastic polyimide film having a water vapor transmission rate equal to or more than 170 g - μm / m 2 - day , the delamination and whitening of the polyimide metal laminated plate is prevented .
