フレックスリジット基板及びその製造方法

摘要

To provide a flex-rigid substrate that has excellent reliability and in which distortion to the entire substrate is suppressed.SOLUTION: A flexible rigid substrate (1) having a flexible portion (3) and a rigid portion includes a first insulating portion (10) having flexibility, a conductor-equipped insulator (20) formed of a first conductor layer (12) and a second conductor later (14) formed on the front and back surfaces of the first insulating portion, a second insulation portion (16) laminated on the surface of the first insulating portion of the conductor-equipped insulator and a component region of the flexible portion and the rigid portion, and a third insulating portion (30) laminated on the surface of the second insulating portion and in a component region of the rigid portion, and the second insulating portion and the third insulating portion are made of a prepreg.SELECTED DRAWING: Figure 1
