The JEDEC high-K (2s2p) board design used to derive this data was a 3-inch x 3-inch (7.5-cm x 7.5-cm), multilayer board with 1 ounce
internal power and ground planes and 2 ounce copper traces on top and bottom of the board.
(2)
The JEDEC low-K (1s) board design used to derive this data was a 3-inch x 3-inch (7.5-cm x 7.5-cm), two-layer board with 2 ounce
copper traces on top of the board.
