[0002] In the prior art, printed circuit board technology is developing towards multi-layer and multi-functionality. Many printed circuit boards need to be bent multiple times in different planes, which requires the substrate of the printed circuit board to have better flexibility. With the maturity of printed circuit technology, a rigid-flexible board has emerged, which includes both a rigid part and a flexible part. The rigid part has high flatness and mechanical strength, while the flexible part can be bent, which provides flexibility and freedom for the design of the circuit board. Therefore, the rigid-flexible circuit board can connect circuits on different planes.
