Hello--
At a recycling center where I volunteered, a manufacturer dropped off
several gaylords full of electronic scrap, including a batch of thick (1/8")
circuit boards assembled with lead-free solder. The boards had failed
final test and were discarded because they couldn't be reworked due
to through-hole pullout. I found that while I could salvage individual
components, I invariably ruined the board, and I suspect that factory techs
had the same experience.
If the intent behind adoption of RoHS was the reduction of electronic
waste, I wonder
how much of the waste stream now consists of unrepairable lead-free-soldered
products?
Getting the lead out of gasoline likely made much more of a difference
in the overall
lead burden than removal of lead from solder.
