There are certainly several good reasons to keep components 2 mm inside the board outline. In Protel, rather than draw a keepout line 2 mm inside the board outline, I find it more convenient to draw the keepout line exactly on the board outline, but with "fat traces" 4 mm wide. Both techniques have the same effect, right? (OK, what I really do is make the keepout traces 0.120 inch wide -- keeping traces 0.060 inch back from the edge. Then I add a rule to force a keepout-component gap of 0.040 inch, which has a net effect of keeping components 0.100 inch back from the edge.) -- David Cary http://protel-users.org/ http://en.wikipedia.org/wiki/PCB_layout_guidelines ____________________________________________________________ You are subscribed to the PEDA discussion forum To Post messages: mailto:[email protected] Unsubscribe and Other Options: http://techservinc.com/mailman/listinfo/peda_techservinc.com Browse or Search Old Archives (2001-2004): http://www.mail-archive.com/[email protected] Browse or Search Current Archives (2004-Current): http://www.mail-archive.com/[email protected]
