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. Inge ----- Original Message ----- From: "Victor G.

I have cross sectioned several communication cards with supposedly embedded passive and have not found one yet. How about a conceptual drawing.
