Hi All, I just posted the following - Gaps in return planes - yes or no? I present arguments from an EMC and SI viewpoint where I feel they can be bad news, but Id be interested in cases or scenarios where gaps in return planes are OK or maybe even preferred. http://www.edn.com/electronics-blogs/the-emc-blog/4429950/Gaps-in-return-planes---yes-or-no- Your insightful thoughts are solicited Cheers, Ken _______________________ Ken Wyatt Wyatt Technical Services LLC ken@xxxxxxxxxxxxxxxx www.emc-seminars.com Phone: (719) 310-5418 ------------------------------------------------------------------ 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 forum is accessible at: http://tech.groups.yahoo.com/group/si-list List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
