Abstract: A strain relief plug to restrict movement of wires on a printed circuit board, the strain relief plug having an elongated stem along a vertical axis of the strain relief plug. The strain relief plug has an in-board flange defined by the elongated stem, the in-board flange configured to seat in a bore defined by the printed circuit board. The strain relief plug has an anchor defined by a first end of the elongated stem configured to prevent the strain relief plug from releasing from the printed circuit board. The strain relief plug has a bar defined by a second end of the elongated stem and transverse the vertical axis, the bar forming wire channels. The strain relief plug provides strain relief for wires on the printed circuit board of an electric motor in a vertical dimension resembling the thickness of the printed circuit board.

Abstract: A printed circuit board has a solder joint inspection system including a substrate surface having at least one solder pad thereon, at least one conductor wire having an end attached to the at least one solder pad, and a first inspection feature. A first inspection feature is marked on the substrate surface adjacent to the at least one solder pad to define a conductor end zone on the at least one solder pad. The end of the conductor wire is in the conductor end zone when properly attached. The at least one solder pad may define a second inspection feature to mark an extent to which the at least one solder pad is covered by a flow of solder when the wire is properly attached.

Abstract: A system for measuring temperature in an electric motor, including a stator with field windings in the electric motor and a circuit board proximate to the field windings. The system further includes one or more thermo-electric temperature responsive devices. The thermo-electric temperature devices are mountable onto a surface of the circuit board facing the field windings. The system further includes a thermally conductive, but non-electrically conductive material, connecting the one or more thermo-electric devices to the stator windings.

Abstract: A printed circuit board having an electrically insulative layer and a conductive solder pad. The conductive solder pad is disposed at least partially over the electrically insulative layer, and defines a solder contact area. The solder contact area is configured for making an electrical connection to an electrical component via laser soldering. The printed circuit board further includes a solder mask coating the conductive solder pad and defining an exposed area of the conductive solder pad. The conductive solder pad protects the electrically insulative layer from incident heat during the laser soldering by extending a length underneath the solder mask along a periphery of the exposed area.
