The guys who are electronics techs in this thread are sure to know more than I do, but I did read that Germany/Austria does not permit the use of lead in solder. Don't know if that is true, but whatever the composition of the solder it seems to be subject to cracking over time. If one is going to go to the trouble of re-melting all the affected solder joints, it would seem that the better way to go would be to use a wick or solder sucker and re-solder the joint with a good electronics solder containing the appropriate lead-tin composition. Is this good info, or am I off base here?
