I've looked into this, but I'm torn. In my mind the most compelling arguments against lead-free are: of the studies of factory workers who work every day with lead/tin solder, they couldn't find elevated blood lead levels; and that the fluxes in lead-free solders are both more exotic (i.e. less studied for adverse health effects) and a greater proportion of the solder. The danger of absorbed lead is clear, but it's not a straight line from there to lead-free solder. Furthermore, the process that resulted in the EU (mostly) banning lead solder seems to be based more on the precautionary principle than any evidence of health or environmental damage from solder specifically. Added to that is some definite PR misinformation floating around - it's been hard for me to come to any conclusions. |
