Lead free is, I think, tin, bismuth, and silver (might have
remembered this properly).? However, it does not play well with
low temperature soldering and is (AFAIK) inferior in all respects
to what one would want in solder.? I have never heard of a
eutectic mix, so the low melting temperature doesn't happen with
lead free.? This puts more stress on parts, let alone makes
soldering more difficult.? Yep, tried lead free, didn't' work as
well.
Now the chip-quik has a much lower melting point (IIRC, pure
bismuth has a rather low mp, but again, could be wrong).? The
chip-quik is designed to alloy and melt at a lower temperature,
making removal of large ICs easier.
They do say that you can use it for soldering directly, but
that's a good question about how and what.

Thanks Harvey,
? I bought a syringe of
as per Stefan's post above. I have read about a foreign brand
named Mechanic that most people give it high marks.
I also watched some video's earlier today about flux cleaners and
in one of them they said MG's the winner.
Isn't bizmuth the stuff that is in lead free solder, or is it some
new type? I guess it is a new type because from what I read, lead
free has a higher melting point that no lead solder. I have no
clue as I never tried it.
