BGA Via

The BGA Via tab calculates the vertical via loop inductance under the BGA pin field.

Figure 1–3 is a snapshot taken from the tool.

You enter the layout-specific information, such as the via drill diameters, via length,

via pitch, and the number of power/ground via pairs under the BGA. The tool

calculates the effective via loop inductance and resistance value. You can save the

change made to the tab, restore the changes, and restore the tab back to the default

settings.
