Back in 1984 my uncle Dave taught me how to wire up ham radios in his shed and we never touched this modern lead-free junk. These youngsters keep melting switch housings because they have their iron cranked up to 400C trying to melt lead-free silver alloy. A decent spool of Kester 63/37 leaded rosin core will do fifty boards without ruining the copper traces. Just put a small desk fan on to blow the fumes away from your spectacles. People love making simple electronics harder than they need to be.
