Abstract:
1. A flexible printed circuit board, for connecting external modules, comprising: a high-frequency signal wiring board and a low-frequency signal wiring board, wherein side edges of the high-frequency signal wiring board and the low-frequency signal wiring board are connected to each other, the low-frequency signal wiring board is folded toward the high-frequency signal wiring board to form a stacked double-layer board structure, and each of two ends of the high-frequency signal wiring board extends to form a connecting board for connecting the external module; wherein each connecting board at each end of the high-frequency signal wiring board is provided with a plurality of high-frequency signal contacts and a plurality of low-frequency signal contacts; wherein the high-frequency signal wiring board is provided with a plurality of high-frequency signal traces correspondingly connected to the high-frequency signal contacts on the two connecting boards; wherein the low-frequency signal wiring board is provided with at least one low-frequency signal trace correspondingly connected to the low-frequency signal contacts on the two connecting boards; and wherein a part of the low-frequency signal trace passes through the high-frequency signal wiring board.
