Abstract:
1. An area array package comprising: a substrate having a coupling surface configured to couple to a circuit board, the coupling surface having a central area and a peripheral area surrounding the central area; a grid array of primary electrical contacts coupled to the coupling surface within the central area defined by the coupling surface, the grid array of primary electrical contacts configured to carry at least data signals between the area array package and a circuit board; and a series of secondary electrical contacts coupled to the coupling surface and oriented within the peripheral area defined by the coupling surface, the series of secondary electrical contacts configured to carry power signals between the area array package and the circuit board, the series of secondary electrical contacts being separate from the grid array; wherein the grid array of primary electrical contacts comprises a plurality of primary solder balls, each primary solder ball of the grid array of primary electrical contacts defining a first diameter; wherein the series of secondary electrical contacts comprises a plurality of secondary solder balls, each secondary solder ball of the set of secondary electrical contacts defining a second diameter, the second diameter defined by each of the secondary solder balls being greater than the first diameter defined by each of the primary solder balls; and wherein the substrate defines a length of at least approximately 60 mm and a width of at least approximately 60 mm.
