Adeel I just had a look at the spec and it would seem that layer names are not specified. So whilst the extensions used in Protel may be nominally the most common they are not the only ones used.
Personally I think that you should always include layer stackup instructions within your PCB file or in a text file that goes with the gerbers that details the stackup etc. Ian Capps ----- Original Message ----- From: "Adeel Malik" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Monday, February 07, 2005 11:34 PM Subject: [PEDA] Protel Gerber File Extensions,Are they conform to Standard Industry Practice ??? Hi All, My PCB vendor asks me that in order to correctly ascertain about the identity of Top Layer and Bottom Layer, I should manually write the string "TOP" in the Top Copper Layer and string "BOTTOM" in the Bottom Copper Layer. I tell him that this information is embedded in the Gerber File extensions itself. e.g Design.GTL and Design.GBL means that these files correspond to Top Copper and Bottom Copper Layers respectively. I wanna ask whether this naming of Gerber file extensions by Protel conforms to standard Industry Practice or not ?. If yes, can someone comment about the legitimacy of my PCB Vendor's opinion that I need to mention the layer name in text manually. ?....
