Norman Einarson did a lot of writing about stripline calculations and design criteria for multilayer boards. They appeared in a pc design manual for PC World. I'm not sure where he is these days, but you could try the last number I have for him, 617-938-1440. I believe that I also saw Norm's name on the TechNet some time ago. ______________________________ Reply Separator _________________________________ Subject: Propagation time formula Author: Doug Brooks <[log in to unmask]> at 0UTG0ING Date: 2/6/97 1:27 PM Various sources (e.g. IPC) have formulas for propagation delay for microstrip and stripline configurations. Does anyone know of a formula for propagation time in a DUAL stripline configuration? Or is the stripline configuration close enough?
