Because of physical limitations, I am considering reducing all of the ref planes on a design to 1/2 oz. copper (was 1 oz. copper). The board level logic is 3.3V CMOS. Does anybody see any problems with doing this? thanks, Jim ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List archives are viewable at: //www.freelists.org/archives/si-list Old list archives are viewable at: http://www.qsl.net/wb6tpu
