Mike,
        please settle down.  I am sorry that you felt I was attacking you
personally. I did not attack you or your comments, challenge you or your
experience, I only responded to your statement quoted below.

        "The only conditions in which we specify a thickness and we only
spec it for these layers, are controlled impedance, and where the min
dielectric breakdown voltage is required for Bell-Core, FCC, and space
applications."

        Now does that not sound like the situation I was describing, it
sounds as though you were saying that you do not specify the dielectric
(laminate) thickness except in the specified conditions mentioned.

        I cannot remember everyone's experience or abilities to best judge
when a statement may have been written poorly or conveyed the wrong idea. My
comment was to point out the possible danger (even in non-specific
performance requirements, i.e. basic digital circuits) of not specifying the
dielectric thickness in all cases. I hope that you can now see the issue
which I responded to, it was not a personal attack nor was it questioning
your abilities and I am sorry that you mistook it as such.
