We know, that electrical values (impedance, L,C) of microvias  are much
lower than of Through hole vias. But we do not know the values 
We  are starting some  experiments to measure them.

Is there any expert who did  already measure or simulate  (by  3D -Solver or
similar)  some microvias  with different  sizes  and  who is interested to
share the  experiences.


Sincerely
Michael Jeremias
