Problems solved by technology

Therefore, more of the actual manufactured product can be sold rather than discarded
Alternatively, it is also possible that one material used in the manufacture of the component costs more than another, but the savings in labor costs more than compensate for the increase in material cost

Embodiment Construction

[0059] Referring to Figures 1-14, several views of various illustrative, exemplary embodiments of magnetic elements or devices are shown. In the exemplary embodiment where the device is an inductor, it will be appreciated that the advantages of the invention described below can also be derived on other types of devices. While the materials and techniques described below are believed to be particularly advantageous for the manufacture of low profile inductors, it will be appreciated that inductors are but one type of electronic component that may benefit from the present invention. Accordingly, the description is made for illustrative purposes only, and it is contemplated that the advantages of the present invention may be realized on other sizes and types of inductors and other electronic components including, but not limited to, transformers. Accordingly, practice of the inventive principles herein is not limited to the exemplary embodiments described herein and shown in the ...

Abstract

A magnetic component and a method for manufacturing a low profile, magnetic component (100). The method comprises the steps of providing at least one sheet (120), coupling at least a portion of at least one winding (140) to the at least one sheet, and laminating the at least one sheet with at least a portion of the at least one winding. The magnetic component comprises at least one sheet (120) and at least a portion of at least one winding (140) coupled to the at least one sheet, wherein the at least one sheet is laminated to at least a portion of the at least one winding. The winding may comprise a clip, a preformed coil, a stamped conductive foil, or an etched trace using chemical or laser etching. The sheet may comprise any material capable of being laminated and / or rolled, including, but not limited to, flexible magnetic powder sheets.

Description

technical field [0001] The present invention generally relates to electronic components and manufacturing methods thereof, and more particularly to inductors, transformers and manufacturing methods thereof. Background technique [0002] Typical inductors may include shaped cores, including shielded and drum cores, U-shaped cores and I-shaped cores, E-shaped cores and I-shaped cores, and other matching shapes. Inductors typically have conductive wire wrapped around a core or clip. Wound wire is commonly referred to as a coil and is wound directly onto a drum or other spool core. Each end of the coil may be referred to as a lead and is used to couple the inductor to the circuit. The discrete cores can be bonded together by adhesives. [0003] With the development of electronic packaging technology, it has become a trend to manufacture power inductors with miniature structures. Thus, core structures must have increasingly lower profiles so that they can accommodate modem el...
