     I am looking to see if anyone has the calculations for " Dual
     Stripline " controlled impedance in a spreadsheet type of formula. I
     have all the others, but this particular type has just reared it's
     ugly head, and we haven't done this board type before. I am just
     trying to make sure that my calculations, and lay-ups are accurate.
     Keep in mind I'm not a Math Wizard, hence the need for the spreadsheet
     type of format. Any help will be deeply appreciated. If what you have
     is not proprietary e-mail to [log in to unmask] with any help or
     files. Again, thanks in advance.
