Figure 14 shows an example layout for the ZXY package. This package has a 0.5-mm pitch and requires either micro-vias or very small traces to access the center pins. In this example, 4-mil vias with 10-mil pads are used to access the center pins. All pins are connected by 5-mil traces except for the supply pins which use 10-mil traces.
