There is a demonstration on youtube (make sure to click the hires button): http://www.youtube.com/watch?v=wQXhny3R7lk and for the more advanced: http://www.youtube.com/watch?v=4V7tBPsECjc I can confirm, that this technique works even for lead free solder. The key is the correct tip: It is conical with a flat, side. This flat surface is essential. It will suck the solder not needed for the connection. ---<(kaimartin)>--- -- Kai-Martin Knaak http://lilalaser.de/blog _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
