mmmh...we can talk about the inductance of a circular path, because the =
magnetic flux is defined for the specified rounded area (so we can apply =
the formula L=3Dmagnflux/current). Your "inductance" sounds like the =
partial equivalent inductance in the P.E.E.C. method. But I think only a =
parallelepiped geometry was investigated, and not cylinders or similars.
Try with google looking for "Partial Equivalent Element Circuit", but do =
not forget the other part of the path!

Hi:
=20
Is there any quick formula to estimate the solder ball inductance, given =
the geometric size, such as diameter/height.

thanks,
Han
