Embodiment Construction

[0048] While the following detailed description contains many details for illustration, any person skilled in the art will readily appreciate that many variations and modifications of the following exemplary details are within the scope of the invention. Accordingly, the following preferred embodiments of the invention are set forth without any loss of generality and without imposing limitations on the claimed invention.

[0049] The present invention includes planar magnetic elements in which ferrites or magnets are embedded as elements in a base insulating material with pre-formed openings in which the magnetic (ferrite) unit can be molded, routed by mechanically drilling holes, or stamped into a pre-form Open your mouth. These are then encapsulated in a low stress adhesive, such as a low stress epoxy, set to provide a suitable electrical environment. Copper layers combined with vias enable magnetic building blocks previously built from hand-wound cells in smaller component...

Abstract

The current invention provides an integrated planar transformer and electronic component that includes at least one wideband planar transformer disposed in a planar substrate, where each wideband planar transformer includes a planar substrate in a fully-cured and rigid state, a ferrite material embedded in the planar substrate, where the ferrite material is enveloped in an elastic and non-conductive material, inter-wound conductors disposed around the embedded ferrite material, where top and bottom conductors are bonded by an insulating adhesive. The top and bottom conductors are connected in an inter-connected pattern by conductive vias disposed on each side of the ferrite material and span through the layers to the conductors. The planar transformer further includes at least one center tap connected to at least one inter-wound conductor. The integrated planar transformer and electronic component further includes at least one electronic component connected to at least one terminal of the wide-band planar transformer.
