------------------------------- ....Converting your home lab to "Pb-free" will mostly involve obtaining solder tips approx. 30 C hotter and replacing your Sn-Pb solder with Sn-Ag-Cu solder. The problem for any lab is that absolutely EVERY part in your facility MUST be lead-free. Lead poisons the metallurgy of the lead free solders and this leads to embrittlement and field failure. To go lead-free means we have to maintain isolated stock, and will have to do so until 2006 at the earliest - repairs are not covered by the requirements. In our whole history, we estimate our total "lead output" is about half the weight of a car battery - and how many car batteries are dumped in the environment every day ? Steve |
