Abstract: In a circuit board device having an electronic component mounted on an electrode land on a board by reflow soldering, voids that adversely affect the solder joint in various ways are prevented from forming. The electrode land corresponding to a component electrode for the electronic component is divided into a plurality of land regions by solder resist having a prescribed width. The component electrode is laid above the solder resist so as to form a clearance communicating with the outside of the component electrode, so that gas generated by vaporization of a flux component contained in the solder during reflow-heating is passed through the clearances and let out of the component electrode. In this way, voids in the solder part can more readily be prevented from forming without increasing the number of person hours as compared to the conventional method.

Abstract: The invention is intended to obtain a rotating electric machine with a built-in control device in which the control device is kept from receiving heat from a main body of the rotating electric machine and the control device can be cooled in a desirable fashion. A heat sink (13) on which switching devices (12) of a control device (400) are mounted is attached to a rear bracket (6) by means of conductive studs (300) with a particular spacing provided in a left-to-right direction of FIG. 2. The heat sink (13) is cooled by a flow of cooling air induced by an unillustrated fan. Since the control device (400) is attached to the rear bracket (6) of which temperature increases with the spacing provided therefrom, it is possible to suppress heat transfer from the rear bracket (6) and effectively cool the control device (400) through the heat sink (13).
