摘要： Disclosed herein is a flexible printed circuit board (PCB) of a spindle motor. The flexible PCB includes a solder part, an upper reinforcing plate, a lower reinforcing plate, and a soldering part. The solder part has a through hole so that a coil extending from a stator core passes through the solder part, and has a separation part which is open or closed only in one direction along with the through hole. The upper reinforcing plate supports the upper portion of the separation part. The lower reinforcing plate supports the lower portion of the solder part, and has an elliptical through hole which partially overlaps with the through hole so that the coil passes through the lower reinforcing plate. The soldering part is formed to enable the coil to be secured to the solder part.
