Thanks to all of you that took the time to look into the problem I
had with the IPC calculator. I think Jeff could be right about FR4
being heavier than ohms/impedance so the numbers were higher on top...
I just wanted to flag everyone that what I found is not out of the
ordinary. Pick a calculator and use it, then go to the FAB shop and
give them your numbers to start with. Then use what they give you...
They know what works for them and take what you give them as a starting
place. Again, thanks to those that responded and remember these words:
"Never Forget".....
