A board includes a separating zone in an area closer to the edge than to the center of the board, the separating zone including one elongated through hole. A first group of electronic components that is a source of heat or electric noise is placed in a first area on the center side with respect to the separating zone of the board. On the other hand, a second group of electronic components from which influence of heat or electric noise from other components needs to be eliminated to a maximum extent is placed in a second area on the edge side with respect to the separating zone of the board.

To downsize a power smoothing capacitor substrate unit for opening/closing modules configured to convert a low-voltage DC power to AC power to drive a three-phase AC motor. A plurality of unit capacitors (101) being a conductive polymer aluminum electrolytic capacitor are connected between a positive-side first conductive plate (10P0) connected to a positive-side power supply terminal (125P) and a negative-side second conductive plate (10N) connected to a negative-side power supply terminal (124N), and three or more capacitor rows are arranged for each of three pairs of divided power supply terminal blocks (130B) connected to the opening/closing modules (90B) and one or more capacitor rows are arranged between the terminal blocks. Accordingly, ripple currents in a large number of capacitors connected in parallel to each other are equalized to prevent a temperature increase in each capacitor.

A camera may include a printed circuit board (PCB) that may include at least one coil and at least one position sensor. The coil may be embedded at least partially inside the PCB at a first side of the PCB, whilst the position sensor may be attached to the PCB at a second side opposite the first side. The PCB may include an aperture through the PCB at a location corresponding to the position sensor to enhance sensing of the position sensor. The PCB may further include at least one recess inside which the position sensor may be attached to the PCB.

This motor includes a base and a circuit board arranged on a lower surface of the base. The base includes a first annular portion and a second annular portion. The first annular portion is arranged under a stator. The second annular portion is arranged under a flange portion of a hub. A conducting wire drawn out from the stator is arranged to pass through a through hole defined in the first annular portion, and is soldered to a land portion of the circuit board. The second annular portion is arranged to have an axial thickness smaller than that of the first annular portion. The land portion is arranged radially inward of the through hole. The above arrangement makes it easier to achieve a reduced axial dimension of the motor while ensuring a sufficient axial dimension of the hub, which is arranged axially above the second annular portion.

An electronic component mounting substrate includes an electronic component mounted on a surface of a substrate, an electrode portion disposed on the surface of the substrate and electrically connected to the electronic component, a lead wire connected to the electrode portion, and an encapsulation resin configured to encapsulate a part of the lead wire, the electronic component, and the electrode portion. A surface of at least the part of the lead wire encapsulated by the encapsulation resin and the surface of the substrate are coated with a deposited film.
