Patent ID: 7729131

Claim:
An electronic device, comprising: a first board; first circuit components coupled to a first circuitry side of the first board; a first board-to-board coupler coupled to the first circuitry side of the first board; a second board; second circuit components coupled to a second circuitry side of the second board; a second board-to-board coupler coupled to the second circuitry side of the second board; a first interference shield structure having a first planar portion and first side portions coupled to a first shielding side of the first board opposite the first circuitry side; and a second interference shield structure having a second planar portion and second side portions coupled to a second shielding side of the second board opposite the second circuitry side, wherein the first and second interference shield structures mate with each other to hold the first board and the second board in a vertical stack, wherein the first and second interference shields substantially surround the first and second circuit components to provide electromagnetic shielding for the first and second circuit components, wherein the first and second board-to-board couplers are electrically connected in the vertical stack, wherein the first circuitry side and the first circuit components face the second circuitry side and the second circuit components in the vertical stack, wherein each of the first circuit components is horizontally offset from each of the second circuit components in the vertical stack, and wherein there is no shielding layer interposed between the facing first and second circuitry sides of the first and second boards.
