Encapsulated package for a magnetic device
View Patent ↗An encapsulatable package for a magnetic device that includes a magnetic core. In one embodiment, the encapsulatable package for the magnetic device also includes a shielding structure located about the magnetic core configured to create a chamber thereabout. The shielding structure is configured to limit an encapsulant entering the chamber.
1. An encapsulatable package for a magnetic device, comprising:
a magnetic core; and
a substantially rigid shielding structure located about said magnetic core configured to create a chamber surrounding said magnetic core and configured to limit a substantially non-compliant encapsulant from entering said chamber during encapsulation of said magnetic device, thereby protecting said magnetic core from said encapsulant.
2. The encapsulatable package for said magnetic device as recited in claim 1 wherein said shielding structure is configured to allow at least a portion of said encapsulant to exit said chamber as said encapsulant cures.
3. The encapsulatable package for said magnetic device as recited in claim 1 wherein said shielding structure is configured to limit an exposure of said magnetic core to said encapsulant.
4. The encapsulatable package for said magnetic device as recited in claim 1 wherein said shielding structure creates a partial seal about said magnetic core.
5. The encapsulatable package for said magnetic device as recited in claim 1 wherein said shielding structure creates an opening with an underlying substrate.
6. The encapsulatable package for said magnetic device as recited in claim 1 wherein said shielding structure is a protective cap.
7. The encapsulatable package for said magnetic device as recited in claim 1 wherein said shielding structure is formed from a material selected from the group consisting of:
a ceramic material,
aluminum,
copper, and
molded plastic.
8. The encapsulatable package for said magnetic device as recited in claim 1 wherein said chamber is substantially free of any material about said magnetic core.
9. The encapsulatable package for said magnetic device as recited in claim 1 wherein said magnetic core is a ferrite core.
10. The encapsulatable package for said magnetic device as recited in claim 1 further comprising at least one conductive winding about said magnetic core.
11. An encapsulated package for a magnetic device located on a substrate, comprising:
a magnetic core;
a substantially rigid shielding structure located about said magnetic core configured to create a chamber surrounding said magnetic core; and
a substantially non-compliant encapsulant about a portion of said magnetic core within said chamber, said shielding structure configured to limit said encapsulant from entering said chamber during encapsulation of said magnetic device, thereby protecting said magnetic core from said encapsulant.
12. The encapsulated package for said magnetic device as recited in claim 11 wherein said shielding structure is configured to allow at least a portion of said encapsulant to exit said chamber as said encapsulant cures.
13. The encapsulated package for said magnetic device as recited in claim 11 wherein said shielding structure is configured to limit an exposure of said magnetic core to said encapsulant.
14. The encapsulated package for said magnetic device as recited in claim 11 wherein said shielding structure creates a partial seal about said magnetic core.
15. The encapsulated package for said magnetic device as recited in claim 11 wherein said shielding structure creates an opening between a junction of said shielding structure and said substrate.
16. The encapsulated package for said magnetic device as recited in claim 11 wherein said shielding structure is a protective cap.
17. The encapsulated package for said magnetic device as recited in claim 11 wherein said shielding structure is formed from a material selected from the group consisting of:
a ceramic material,
aluminum,
copper, and
molded plastic.
18. The encapsulated package for said magnetic device as recited in claim 11 further comprising a stand off between said magnetic core and said substrate.
19. The encapsulated package for said magnetic device as recited in claim 11 further comprising electrical leads protruding from sidewalls of said substrate.
20. The encapsulated package for said magnetic device as recited in claim 11 further comprising at least one conductive winding about said magnetic core.
