Structure including spindle motor and printed circuit board

A spindle motor structure comprising:

• a spindle motor including a stator having a core wound with a coil and a rotor rotating about the stator;
• a driving substrate aligned at an outer periphery of the rotor and soldered with driving control parts of the spindle motor including a plurality of circuit parts including a driving integrated circuit and the like;
• a core substrate aligned at an inner side of the rotor and installed with the core and to which the coil is soldered and connected to the driving substrate;
• and
• a base on which the spindle motor, the driving substrate and the core SUBSTRATE are installed, wherein the spindle motor or the core substrate is assembled with or dissembled from the base independently from the driving substrate.

A spindle motor structure comprising:

• a base;
• a spindle motor installed on the base including a rotation shaft, a rotor simultaneously rotating with the rotation shaft, a core fixed between the rotation shaft and the rotor and a stator having a coil wound on the core and rotating the rotor;
• a core substrate connected with the coil by being installed at an area of the base inside the rotor for insulating the coil and the base;
• and
• a driving substrate installed on the base at an outer periphery of the rotor and connected to the core substrate by a soldering process,
• wherein the area of the base corresponding to an area between the core substrate and the driving substrate is formed with a discharge hole for inhibiting a solder from flowing backward.
