Abstract:
In one aspect, a method for configuring a ball grid array is disclosed. The method may include identifying a number of balls for use in a ball grid array, determining a number of rows and a number of columns for the ball grid array, and populating the ball grid array at least in part with a plurality of ball-space groupings. The method may also include allocating an unpopulated portion of an area bounded by the at least one first outside row, the at least one second outside row, the at least one first outside column, and the at least one second outside column, to be free of balls. The method may also include routing a signal line from a ball of at least one ball-space grouping to a space of the at least one ball-space grouping and routing the signal line to a substrate layer through a via.
