I'm not sure now if I have used a plane layer on the outside of a board, but I have used a single ground plane plot for two physicial layers in a board. As others have mentioned (and I didn't think of, at the time), a ground plane won't have any pads around the holes, so it might not be a good idea to use one on the surface of the board. ************************************************************************ * Tracking #: 2257EAB63D835E45B29F432319B4FF0452F2A00E * ************************************************************************ -- Peter Bennett TRIUMF 4004 Wesbrook Mall, Vancouver, BC, Canada GPS and NMEA info and programs: http://vancouver-webpages.com/peter/index.html * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[email protected] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
