Pb free solder is often brittle and cracks easily under thermal cycling,
stress or vibrations.
Standard procedure round here is to remove it with wick and use some real
60/40 Savbit solder to make the repair.

This week a 6 month old amp with 2 separate PbF faults found. Plus loads of
other problems. Test with dummy load , then speaker. Place back in the cab
and supposed final test - another damn intermittant fault. Maybe just
induced by my localised handling on the power amp is enough to have
disturbed another only just holding lead-free solder joint. Luckily the
owner has another amp he cab use and this one can sit until next week when I
may be in a calmer frame of mind .

probably the biggest negative reliability impact on electronic equipment,
since printed circuit construction was first introduced to the commercial
market 40 odd years ago, and was at that time itself an unreliable
technology. By 15 years ago, this type of construction and manufacturing was
a fully mature and stable technology, with a very high degree of intrinsic
reliability. Until poxy lead-free solder was forced on everyone by idiots
who didn't understand the implications. PCB construction is now probably
about as unreliable as back in the early days of the technology. Avionics,
military and life support equipment manufacturers won't use the stuff, and
have successfully negotiated exemptions from the mandate, for their classes
of equipment. That should probably tell you all that you need to know ...

If you live where lead free is a commercial reality, who is going to
know if you use good old 60/40 (63/37) to fix your own stuff?
I've reworked many lead free boards with lead solder, and we use 100's
of thousands of ROHS parts with good old 63/37.
Here in the US we can use real solder that really works, so no issue.Phil Allison wrote:
