Abstract: A printed circuit board (PCB) assembly is provided. The PCB assembly comprises a printed wiring board (PWB) and one or more electrical components mounted thereon. The PWB comprises a plurality of layers including conductive layers and insulative layers, where one or more of the insulative layers is a prepreg layer that is halogen-free; one or more slotted portions on a surface of the PWB, which are indented into the PWB; and one or more pads disposed on the surface of the PWB, which are paired with the one or more slotted portions. Each of the one or more electrical components is mounted on the surface of the PWB through a pair of a slotted portion and a pad.

Abstract: An inductor is disposed above and mounted on a printed wire board. The inductor includes a winding and a core. The winding includes first and second terminations that are electrically connected to the printed wire board at different locations. The core includes: a first section including magnetic material with a channel along an inner surface, to receive the winding, and ending at or above first and second bottom corners of the inner surface; a second section that is a mirror image of the first section including an inner surface that faces the inner surface of the first section; and a distributed gap that uniformly separates the first section from the second section except where the winding passes along the mirror-image channels. The winding lies along the distributed gap in the mirror-image channels, and the winding spatially divides the core into an upper and lower portions of equal volume.

Abstract: A transformer, such as a current sense transformer, in which conductive traces disposed within a printed circuit board serve as the primary winding of the transformer. The transformer also includes a secondary winding, for example wound around a hollow pin of a bobbin, through which a leg of a magnetic core is disposed. The magnetic core leg, and in some embodiments also all or a part of the secondary winding, is inserted into a through-hole in the printed circuit board that is surrounded by the primary winding traces.

Abstract: A magnetic device is provided that may be employed with surface mount technology. In an advantageous embodiment, the magnetic device includes a magnetic core having a magnetic core half and a springable winding positioned about at least a portion of the magnetic core half. The springable winding includes a terminus biased against the magnetic core half.

Abstract: A magnetic device and a method of manufacture therefor. In one embodiment, the magnetic device includes: (1) a bobbin having a winding guide and molded-in margins proximate opposing inside flanges of the bobbin, each of the opposing inside flanges having at least one notch formed in an inside face of each of said opposing inside flanges; (2) an inner winding wound about the winding guide and between the molded-in margins; (3) an outer winding wound about the inner winding and the winding guide and between the flanges; and (4) an insulating plate, provided in the at least one notch and interposed between the inner and outer windings, a thickness of the insulating plate providing a predetermined creepage distance between at least one lead of the inner winding and the outer winding.
