I can't promise you, but I have made a note in my puter. You may have to
wait until I get time and hardware. We have designed inductors, capacitors
and other "passives" for years, and it seems to be rather simple things  to
create.  Some transformers are made in such a way, that the coil is part of
the PWB copper and you  just mount the iron core on top. Couplers are made
likewise. Why do you need a cross section? Not much to see, just copper and
dielectric.
Note: the passive components are normally in the top and second layer, not
deeper.

Subject: [TN] PWB embedded passive devices


Fellow TechNetters:

   Can anyone out there share a cross section photo of am embedded
passive device.
I have cross sectioned several communication cards with supposedly
embedded passive and have not found one yet.
How about a conceptual drawing.

Victor,
