Claims
- 1. A magnetic device, comprising:
- a multi-layer circuit containing a plurality of windings disposed in layers thereof, said multi-layer circuit having inner lateral vias associated therewith, said inner lateral vias intersecting said layers of said multi-layer circuit;
- a conductive substance disposed within said inner lateral vias and electrically coupling selected ones of said plurality of windings;
- a magnetic core mounted proximate said plurality of windings and adapted to impart a desired magnetic property to said plurality of windings; and
- a compression-mounted electrical lead resiliently bearing against said conductive substance and electrically coupled to electrical conductors on a substantially planar substrate to conduct electricity therebetween, said plurality of windings and said magnetic core substantially free of a surrounding molding material to allow said magnetic device to assume a smaller overall device volume.
- 2. The device as recited in claim 1 wherein said substantially planar substrate has a window defined therein, said magnetic core at least partially recessed within said window thereby to allow said magnetic device to assume a lower profile.
- 3. The device as recited in claim 1 wherein a solder at least partially fills said inner lateral vias to allow said inner lateral vias to act as conductors between said plurality of windings and said electrical conductors on said substantially planar substrate.
- 4. The device as recited in claim 1 wherein said multi-layer circuit comprises outer lateral vias located therethrough and intersecting said layers of said multi-layer circuit, a conductor disposed within said outer lateral vias further electrically coupling said selected ones of said plurality of windings.
- 5. The device as recited in claim 1 wherein said compression-mounted electrical lead is a clamp.
- 6. The device as recited in claim 1 wherein said magnetic core surrounds and passes through a central aperture in said plurality of windings.
- 7. The device as recited in claim 1 further comprising a plurality of inner lateral vias formed on opposing ends of said multi-layer circuit.
- 8. The device as recited in claim 1 wherein said plurality of windings form primary and secondary windings of a power transformer.
- 9. The device as recited in claim 1 wherein said magnetic device forms a portion of a power supply.
- 10. The device as recited in claim 1 wherein said magnetic core comprises first and second core-halves.
