IMHO, this layer is usually iron and not that fine -- abut half a mm. There might be some additional chemical "activation" involved. But I am not sure. > If the point was too hot, this fine layer peels off, I'd say, it oxidizes. Unlike oxidized solder, this rust sticks to the tip. It requires more force to rub it off. ---<)kaimartin(>--- -- Kai-Martin Knaak tel: +49-511-762-2895 Universität Hannover, Inst. für Quantenoptik fax: +49-511-762-2211 Welfengarten 1, 30167 Hannover http://www.iqo.uni-hannover.de GPG key: http://pgp.mit.edu:11371/pks/lookup?search=Knaak+kmk&op=get _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
