Abstract
A flat vibration motor including a stator having a spindle for mounting a flexible substrate, and a rotor having an eccentric weight and rotatably supported by the spindle, the flexible substrate having a lower surface substrate overlapped on the lower surface of the stator and centered around the spindle, an upper surface substrate overlapped on the upper surface of the stator plate, and a narrow-width connecting part for connecting the lower surface substrate and the upper surface substrate by bending the lower surface substrate and the upper surface substrate in an integrated fashion at a notch in the circumference of the stator plate, and the upper surface substrate having a through hole for fastening and connecting an upper surface wiring pattern with the stator plate by filing solder bump, whereby reflow soldering in automatic mounting of a printed circuit of instrument side can be performed.
