The IPC J-STD-006 tolerance is +/- 0.2% for alloys less than 5% of a metal
constituent.

Subject: [LF] Lead-free tolerances


We're starting our in-house evaluation of lead-free solder.  The composition
we are initially looking at is 95.5Sn-3.8Ag-0.7Cu.  Our current spec for
SnPb has a +/- tolerance of 0.5% on the composition.  What kind of tolerance
will the lead-frees have?  How much of an effect will the variability have
on solidus/liquidus temperatures?  Just curious as to what others are doing.
