A second tier of signal contacts is arranged around the periphery of the die attach area on the first surface of the substrate. A power contact tier is also arranged around the periphery of the die attach area on the first surface of the substrate. The power contact tier is arranged between the first tier of signal contacts and the second tier of signal contacts to reduce signal noise and cross talk between the signal bond wires of the first tier and the second tier.

摘要： A two layer PBGA which includes a metal ground plane at its bottom layer. The ground plane is preferably a metal plane which is connected to ground through a metal connection to a ball pad at the center of the package and a ball pad proximate the edge of the package. The ground plane is voided around the signal and power balls, via and “dog bones”. The PBGA is configured such that the ground plane serves effectively the same function as the second layer ground plane in a conventional four layer PBGA. The PBGA provides a cheaper alternative to the generally more expensive four layer PBGA, and provides better cross talk performance (especially for high frequency signaling) as well as better thermal performance as a result of having more metal at the bottom layer of the package.
