Abstract

The invention relates to a rigid-flex board and a manufacturing method thereof, the rigid-flex board comprises a first flexible core board, a second flexible core board, a first circuit board and a second circuit board. One side surface of the first circuit board and one side surface of the second circuit board are connected with the first flexible core board, the other side surface of the first circuit board and the other side surface of the second circuit board are connected with the second flexible core board. In the rigid-flex board, regions, corresponding to an interval between the firstcircuit board and the second circuit board, on the first flexible core board and the second flexible core board are the regions which can be bent, thus, a bending function of the rigid-flex board is realized. Moreover, the first flexible core board and the second flexible core board have enough signal transmission lines for conducting electronic elements on the first circuit board and the second circuit board. Moreover, transmission signals of an external device are directly transmitted to the first flexible core board and the second flexible core board at an external surface, thus, the transmission signals are free from producing loss while passing through via holes.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a rigid-flexible circuit board and a production method thereof. Background technique [0002] In the traditional rigid-flexible board, before the step of laminating the rigid core board and the flexible core board, the rigid core board located on the outside is subjected to window opening treatment, and the area corresponding to the flexible core board and the window opening position is the bending area. The rigid core board and the flexible core board are laminated into a rigid-flex board. After lamination, the flexible core is clamped between the rigid cores. The transmission signal of the external equipment is first transmitted to the rigid core board on one side of the surface layer of the rigid-flex board, and then transmitted to the inner flexible core board through the via hole of the rigid-flex board, and the flexible core board transmits the transmissio...
