Hi all, I would like to thank the forum for all the great info I received on controlled impedance (especially Jeff Seeger, Earl Moon and Mitch Morey). The consensus was to call out all needed data in the Master Drawing, this said I would like to request if possible some assistance with the proper notes. If any of you have some controlled impedance notes you would be willing to share I would appreciate. I would also like to see how some of you may have converted from MIL-P-13949 to IPC-4101.
