Hi! Is there a difference in terms of electrical parameters i.e. say loss, etc when using single symmetric stripline layer and dual stripline layer. I guess I am asking beside the cost & geometry is there a harm if I use dual stripline layer over single stripline layer where adding more routing layer is necessary for me. I ran cases to look at differences if I route edge coupled differential traces on single symmetric stripline or if I use dual stripline. I did not any difference at least in loss or impedance etc. Any input is appreciated. THanks Bob __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier.
