I would like to calculate the impedance of a solid (filled) via and compare it with that of a plated via.
I know the dimensions of the via but I just don't know the equation for resistance. It is the same for that of a strip of copper on a PCD trace just the only thing different is the way you calculate area?
Stripline R: pL/A
where: p = resistivity; L = length; A = cross sectional area
Thanks.
