Adeel Most PCB houses should be able to set up a customer information profile for you. This should include naming conventions for the files you deliver. Normally I have a nice picture and some info file I supply to inform them of how protel names layers etc. It certainly would not do any harm to annotate your layers as they ask, even if it is outside your board outline so they can delete it after. It will reduce the risk of error. If you use the layer stackup legend this should help you a bit. You can never have enough documentation for this... :-) John ____________________________________________________________ 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]
