Low-profile assemblies for providing board level EMI shielding for electrical components on opposite sides of printed circuit boards
First Claim
1. An assembly for providing EMI shielding for electrical components on generally opposite first and second sides of a board, the assembly comprising:
- a frame attachable to the board'"'"'s first side, the frame including walls and at least one opening along an upper portion of the frame, the frame'"'"'s walls configured to be disposed generally about one or more electrical components on the board'"'"'s first side;
a first cover configured to cover the at least one opening of the frame;
a second cover attachable to the first cover with the first and second covers respectively positioned along the board'"'"'s generally opposite first and second sides;
whereby the assembly is operable for shielding one or more electrical components on the board'"'"'s first side that are within a first interior defined by the frame'"'"'s walls, first cover, and at least a portion of the board'"'"'s first side, and one or more electrical components on the board'"'"'s second side that are within a second interior defined by the second cover and at least a portion of the board'"'"'s second side.

Abstract
An EMI shielding assembly generally includes a frame attachable to the board'"'"'s first side, and first and second covers configured to be respectively positioned on generally opposite sides of the board. The first cover is configured to cover at least one opening along an upper portion of the frame. The second cover is attachable to the first cover with the first and second covers respectively positioned along the board'"'"'s generally opposite first and second sides. Accordingly, the assembly is operable for shielding one or more electrical components on the board'"'"'s first side that are within a first interior defined by the frame'"'"'s walls, first cover, and at least a portion of the board'"'"'s first side, and one or more electrical components on the board'"'"'s second side that are within a second interior defined by the second cover and at least a portion of the board'"'"'s second side.

18. A low-profile assembly for providing board-level EMI shielding for electrical components on generally opposite first and second sides of a board, the assembly comprising:
-
a frame attachable to the board'"'"'s first side, the frame including walls and at least one opening along an upper portion of the frame, the frame'"'"'s walls configured to be disposed generally about one or more electrical components on the board'"'"'s first side;
a first cover having a lid portion to cover the at least one opening of the frame, and wall portions downwardly depending relative to the lid portion with sufficient length for extending across a thickness defined between the board'"'"'s first and second sides to thereby allow positioning of the end portions of the first cover'"'"'s wall portions on a side of the board opposite that of the lid portion, a second cover;
at least one of said first and second covers including one or more protrusions for interlocking engagement with corresponding openings of the other one of said first and second covers to thereby attach the second cover to the first cover, the interlocking engagement of the one or more protrusions with the corresponding openings also retaining the relative positioning of the first cover generally over the frame with the lid portion covering the at least one opening of the frame;
whereby the assembly is operable for shielding one or more electrical components on the board'"'"'s first side that are within a first interior defined by the frame'"'"'s walls, first cover, and at least a portion of the board'"'"'s first side, and one or more electrical components on the board'"'"'s second side that are within a second interior defined by the second cover and at least a portion of the board'"'"'s second side. - View Dependent Claims (19, 20, 21, 22, 23)

24. A method of providing EMI shielding for electrical components on generally opposite first and second sides of a board, the method comprising:
-
positioning a first cover relative to a frame such that one or more electrical components on the board'"'"'s first side are within a first interior defined by the frame, first cover, and at least a portion of the board'"'"'s first side; and
attaching a second cover to the first cover such that the first and second covers are respectively positioned along the board'"'"'s generally opposite first and second sides, and such that one or more electrical components on the board'"'"'s second side are within a second interior defined by the second cover and at least a portion of the board'"'"'s second side. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
