Abstract:
Embodiments of the invention include inductors integrated into a package substrate that have increased thicknesses due to the use of shaped vias, and methods of forming such packages. In an embodiment of the invention an inductor may be formed in a package substrate may include a first inductor line formed on the package substrate. In some embodiments, a shaped via may be formed over the first inductor line. Additional embodiments may include a dielectric layer that is formed over the package substrate, the first inductor line and around the shaped via. In one embodiment, a second inductor line may also be formed over the shaped via. Some embodiments of the invention may include an inductor that is a spiral inductor.
Abstract:
In described examples, a coil assembly includes a laterally disposed ferrite ring (150) having a central opening (152). A laterally disposed annular conductive member (186) is positioned above the ferrite ring (150) and has spaced-apart circumferential segments. Bond wires (154) are connected at opposite ends thereof to outer and inner portions of the spaced-apart circumferential segments. A layer of mold compound covers the ferrite ring (150) and the bond wires (154).

Abstract:
The invention relates to an electrical device comprising a stack of electrical elements, wherein: a central axis is defined in the stack; each element comprises an electrically insulating carrier; the carrier carries an electrically conductive loop-shaped track; both end zones of the track are located in the edge zone of the carrier; the loop-shaped tracks each form a turn and are arranged around the central axis in the stack; the end zones are connected to each other in electrically conductive manner such that the turns form one winding in at least groupwise manner; the carriers are congruent and each have a form such that they can be rotated from a starting position through an angle a around the central axis to a rotated position in which they take up the same space as in the starting position; adjacent elements with tracks which together form a winding are disposed rotated through an angle α relative to each other, and the mutually registered end zones are mutually connected by an electrical conductor extending transversely of the elements; the free end zones of the tracks of the outermost elements of the stack of elements form the externally accessible terminals of the or each winding; the elements are connected non-releasably to each other, and the stack has a peripheral surface with a form which is prismatic at least in its central zone, i.e. has the same cross-sectional form at any axial position.
Abstract:
A method of making a wireless charging device for an electronic device includes providing a substrate made of glass or glass-ceramic having a shape and size adapted for covering an area of the electronic device. A coil is printed on a surface of the substrate or on a decoration layer on the surface of the substrate using a conductive ink.
