    Abstract: The present invention relates to the methods of construction for inductive components of, preferably, ferromagnetic materials such as inductors, chokes, and transformers when used as an integral part of the fabrication of PCB's or FLEX's. In one preferred embodiment, holes (56, 58) are formed through a ferromagnetic substrate (50) and plated with conductive material. The arrangement of these holes, and the subsequent design that ensues, will form the inductive components within the plane of the media in which the device is formed; using the substrate (50) for a magnetic core (90). By using this approach, the inductive components can be miniaturized to physical sizes compatible with the requirements of modern surface mount technology (SMT) for integrated circuitry (IC). This process also allows these components to be fabricated using mass production techniques, thereby avoiding the need to handle discrete devices during the manufacturing process. In another preferred embodiment, a series of thin, concentric high permeability rings (315) are etched on a substrate (330) to provide high permeability transformers and inductors having minimal eddy current effects.

    Abstract translation: 本发明涉及当用作PCB或FLEX的制造的组成部分时，优选地，铁磁材料如电感器，扼流器和变压器的电感元件的构造方法。 在一个优选实施例中，孔（56,58）通过铁磁性衬底（50）形成并且镀有导电材料。 这些孔的布置以及随之而来的设计将在其中形成装置的介质的平面内形成感应部件; 使用所述基板（50）作为磁芯（90）。 通过使用这种方法，电感元件可以小型化为与集成电路（IC）的现代表面贴装技术（SMT）的要求兼容的物理尺寸。 该过程还允许使用大量生产技术来制造这些部件，从而避免了在制造过程中处理分立器件的需要。 在另一个优选实施例中，在衬底（330）上蚀刻一系列薄的，同心的高磁导率环（315），以提供具有最小涡流效应的高磁导率变压器和电感器。

    Abstract: The present invention relates to transformer inductor devices and to the methods of construction for inductive components such as inductors, chokes, and transformers. Plural via holes 12 are formed through a ferromagnetic substrate 10. Primary 32 and secondary 34 conductors are placed through common vias to form a plurality of cell transformers have 1:1 turns ratio. Circuits connect these primary and secondary winding in parallel and serial combustion to provide a transformer having the desired turns ratio.
