A flat pack blower utilizes surface mounting techniques for mounting the blower electronics on a thin laminated circuit board to reduce the blower profile. To that end, the blower includes a stator, and a rotor rotatably coupled to the stator. The stator includes a coil, a pole coupled with the coil, and a laminated circuit board having blower control circuitry and pads for electrically connecting the blower control circuitry to the coil. Use of surface mounting techniques on the laminated circuit board thus eliminates the discrete electronic components and the wires connecting such components.
