Anyone experience using SnPb wire to gold plated ICs? I have tried to solder the SnPb wire to the gold plated ICs lead, but the surface finishing is dull. Can anyone explain that to me? Why it is not shinny surface? Any recommendation?

take a look at sn100c, less dross & better wetting than sn/pb alloys.

Yes, all the leadfree solders are currently for consumer products. Military and aerospace industry haven't implemented leadfree yet. They are still study which to go! Maybe that time, we all can follow military std and having high reliability product

Now, they realized the problem of the current leadfree alloys. Is there any leadfree alloys finalized to use in future? Will it be a four elements alloys instead of current three elements alloys (eg SAC)?

The only way to resolve these issues is to bring back the good ol� lead and make the joints ductile instead of brittle for an affordable price. Thanks for the link Dave

Or this might be the right solution Alternative lead free soldering reviewed: http://circuitsassembly.com/cms/content/view/4665/95/

lol, you see, all our problems will soon be solved with SodiT potatium solder, dont worry!
