Why not build with a leaded paste or solder pot? You'll have more than 3% lead after solder. Who cares about before solder - any testing will be done on the finished product.

Darby, To my knowledge no case of RoHS (lead) violation has ever gone to court in the EU. The only documented RoHS (lead) violation (again that I�m aware of) has been settled out of court in the UK. Check here: http://www.eetimes.com/news/latest/s

This may be worth checking out are you sure it is flux residue and not undercured plasicizers coming from solder resists due to the higher Lead Free temperatures killing the undercured resist, this causes many no faults found and bridging, solderball

I am curious to know how others are providing N2 for their lead free selective soldering process. If you are utilizing a nitrogen generator, is it a PSA type or Membrane type? I am trying to get a handle on nitrogen purity and what purity is necessar

| | Some of my friends ask me if sombody use lead free solder ball on BGA, espically PBGA packages. I wonder if 96.5Sn/3.5Ag (m.p .221 oC) or 58Bi/42Sn (m.p. 138 oC) would be suitable candidates? Do you have any experience on this subject? | | | | K
