Hi, why not to follow the Standard instructions ? like IPC/JEDEC J-STD-609A.01 2011 February 2011 Marking and Labeling of Components, PCBs and PCBAs to Identify Lead (Pb), Lead-Free (Pb-Free) and Other Attributes Best Regards Gabriele -----Messaggio originale----- Da: TechNet [mailto:[log in to unmask]] Per conto di Upton, Shawn Inviato: venerd́ 16 settembre 2011 14.39 A: [log in to unmask] Oggetto: Re: [TN] standard industry silkscreened symbology for Pb-free assembly I only do in-house boards (well, mostly); but I have one of two logos that I put onto boards: the Pb with a line through it; or a logo that says "Non-RoHS, contains lead". Rare for me to do a board layout without a logo--I figure, it's best to be explicit.

The p.n on lead free has an F suffix.

Some of our products are SnPb and some are Pb-free. It would be helpful to have a Pb-free symbol stenciled onto each Pb-free board. thx Best Regards, -Joe ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
