I've had good luck with the kester 62/36/2% silver stuff, which is
eutectic.

Many many years ago, I had some luck with a indium-bismuth solder paste
in syringes from Indium Corp. Haven't fiddled with any of their stuff
since then.

Radio Shack sells a bag of little peices of tape-form stuff. Never got
it to work well.

Favorites?

plain old 60-40 rosin-core electrical solder has worked well for me - got
mine at a hamfest on a half-pound roll.
the silver stuff (I believe) melts at higher temperatures - and higher
temperatures are not good for electronics.
eutectic (if my memory serves) just means it's either solid or liquid - and
won't just 'soften' - like ice and water.
