BGA Via Tab
The BGA Via tab is used to calculate the vertical via loop inductance under the BGA
pin field.
Figure 1–12 shows teh BGA Via tab.
This tab takes the layout-specific information, such as the via drill diameter, via
length, via pitch, and the number of power/ground via pairs under the BGA for an
effective via loop inductance and resistance value.
