Q: Is paste solder as good as wire or sheet? It certainly seems like
it would be easier to deal with.
A: Paste solder has always seemed to me to be a waste of time for
bench work. It doesn't seem to work as easily or as well as separately applied
paillons of solder and proper flux. I suspect that this is due to the fact
that it's actually formulated more for use in soldering furnaces, which
use a controlled, reducing, oxygen-free atmosphere, instead of with torch
flames. In that use, paste solders work well. But for torch soldering, I've
never liked the stuff at all.
