Buck, I think you will enjoy a paper given at DesignCon in January of this year by Scott McMorrow of Teraspeed. Check it out on their website www.teraspeed.com The article you want to look at is "A Hybrid Measurement and Field Solver Approach..." In my opinion, it is also an example of a state-of-the-art modeling approach with respect to software tools. michael munroe www.copperalliance.net 804-240.7188 "Time is what keeps everything from happing at once" -unknown -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On Behalf Of Kevin Buchanan Sent: Tuesday, August 24, 2004 10:26 AM To: Si-List Subject: [SI-LIST] Mounting pad Design?? Hello All: I'm a student at UMass and am looking for a source of info to find out how to determine the impedance of a footprint pad. What I'm looking for is pointers to reference material or paper(s) on launch design. I would like to do some reading on the subject particularly as it applies to connector footprints. Thank you, Buck... ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
