Problems solved by technology

[0003] However, because the USB signal traces first pass through the printed circuit board and then connect to the flexible circuit board, the routing environment has changed, and the impedance environment on the printed circuit board is inconsistent with the impedance environment on the flexible circuit board. The traces are prone to impedance discontinuity, which cannot meet the impedance connectivity requirements of signal traces

Abstract

The invention discloses a flexible-rigid circuit board and a mobile terminal. The flexible-rigid circuit board comprises a printed circuit board and a flexible circuit board, wherein the printed circuit board is provided with a wiring part and a connecting slot; the connecting slot is formed in one side of the printed circuit board and far from the wiring part; the flexile circuit board comprises a body, and a first side plate and a second side plate connected to the body; the second side plate is positioned on one side of the first side plate; the first side plate and the second side plate are provided with a terminal and a connector respectively; the first terminal is crimped on the wiring part and electrically connected with the wiring part; and the second side plate is laminated on the printed circuit board, so that the connector is clamped in the connecting groove. According to the flexible-rigid circuit board provided by the invention, the second side plate is provided with the connector, the second side plate is laminated on the printed circuit board, and the connector is clamped in the connecting groove of the printed circuit board, so that when the connector is moved to a main board in a wiring manner, the connector is positioned on the second side plate constantly; and therefore, the impedance environment is unchanged, and the impendence continuity of the connector in wiring is ensured.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a rigid-flex board and a mobile terminal. Background technique [0002] At present, when the industry sets up the USB (Universal Serial Bus) signal connector, it usually adopts to set the USB signal connector on the printed circuit board, and then connect it to the main board through a complete flexible circuit board to realize the USB signal connector. The signal transmission between the signal trace of the connector and the motherboard. [0003] However, because the USB signal traces first pass through the printed circuit board and then connect to the flexible circuit board, the routing environment has changed, and the impedance environment on the printed circuit board is inconsistent with the impedance environment on the flexible circuit board. Impedance discontinuity is prone to occur in traces, which cannot meet the impedance connectivity requirements of signal trace...
