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 includes a shielding structure located about the magnetic core configured to create a chamber thereabout and configured to limit an encapsulant entering the chamber. The encapsulatable package for the magnetic device also includes a baffle within the chamber configured to direct the encapsulant away from the magnetic core.
1. An encapsulatable package for a magnetic device, comprising:
a magnetic core;
a shielding structure located about said magnetic core configured to create a chamber thereabout and configured to limit an encapsulant entering said chamber; and
a baffle within said chamber configured to direct said encapsulant away from said magnetic core.
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 baffle is coupled to a sidewall of said shielding structure.
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 shielding structure located about said magnetic core configured to create a chamber thereabout;
an encapsulant about a portion of said magnetic core within said chamber, said shielding structure configured to limit said encapsulant entering said chamber; and
a baffle within said chamber configured to direct said encapsulant away from said magnetic core.
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 baffle is coupled to a sidewall of said shielding structure.
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.
