Folks:
I have a need for in-depth information regarding buildable footprints for
Inter-digitated bypass capacitors (IDCs) in the 0805 size. I am reluctant
to recommend multiple via hits in the pad since I have questions whether it
is worth the hassle.
I also need to find out what is any inductance inductance effects can be
expected when there are thermal vias at the connection points in the
power/ground planes rather than a standard via.
An equivalent circuit would be helpful with different element values for
different pad/via configurations questioned above.
Thanks -
