Hi All, We are currently going to start a new design AMC.1 spec, just starting on the research, anyone done this type of design before ? any good web-sites around where I can research typical stack-up's / routing techniques, there going to be some DDR ram on here but I'm fine with that. Cheers Rich. ___________________________________________________ Try the New Netscape Mail Today! Virtually Spam-Free | More Storage | Import Your Contact List http://mail.netscape.com
