Flexible circuit board structure and fingerprint module of fingerprint module

The embodiment of the utility model discloses flexible circuit board structure and fingerprint module of fingerprint module, it has also increased the technology degree of difficulty because the metal frame is connected to the some elargol to have solved, and elargol itself is also very expensive, and the technical problem of the cost -push that leads to. The utility model discloses the flexible circuit board structure of fingerprint module includes: integrative main subtotal extends coupling part, and the principal part divides and includes: the induction area and the region of windowing, induction area establish with the zone passage winding displacement of windowing there is the electric connection relation, induction area is used for welding the inductor of fingerprint module, it is regional for setting up around induction area outer through spreading the copper mode to window.
