To my surprise, it didn't "flow" and tended to form "icicles" from the joint and the soldering iron at both 750F and 850F. Turns it the alloy was 99.7 Sn (tin) and 0.3% Cu (copper). Nowadays, what lead free alloys have good working characteristics? According to a Hackaday articleon the matter - a bunch of patents are expiring related to lead free solder. --=20 Jason White --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
