never used an eutectic solder, maybe it's better than my standard stuff.
Anyone likes to send me a sample? I have paypal now and can make up for the postage.

Not sure on that, but I have noticed older repairs on some of my 70's gear where they've left behind that horrible brown flux around the joint. This matches what I found when I used some expensive 70's solder recently from Consolidated Alloys here in Oz - it left the same brown flux.
I had just assumed this was the 'real' rosin (pine rosin) and the newer solders used man made rosins which were better. But this is without any research on the topic - I was just guessing.
From some comments in this thread it appears that natural rosin is still used, so my assumptions are probably wrong.

No, real rosin is a part of what they burn in churches, it smells heavenly nice.
What smells bad, is some flux that looks like a paraffin, a "soldering fat". Also, some fluxes were made with Chlorine acid, it may smell bad.
...but a rosin may be guilty as well: some microorganisms eat it, so we were taught strictly to specify removing of any rosin remains from equipment that goes to serve in tropics.

Hey All,
I appreciate all your responses. I did end up getting a roll of 63/37 Kester 44. However, I am curious to try the Cardas Quad stuff. How different would it be to work with than the 63/37 stuff? Whats a good iron temp to work with these solders for pcb work? My guess was about 700 degrees... Any suggestions?
Cheers, Jon 'Uncle Olaf'

Hmmm, well my 60/40 Jaycar solder purchased a couple of years back smells quite nice. Maybe they do still use the real stuff.
Incidentally, for the Aussies out there, I reckon this is good solder for the price.

The quad tends to bond better to silver wires due to it's silver content, and won't eat your iron tips or ic pins etc, due to it's copper content. But it still acts like 63/37 from the eutectic side of things so it melts and sets up much nicer than 60 / 40 or other non-eutectic solders.
I now use Cardas Quad, and it is very, very, good.
I also have a roll of Wonder Solder
and Kester SN62. There is a really expensive solder from WBT that we used for awhile. I wish that I could afford it, but I think I will stick to Cardas Quad, in future.
Most American solder tips are Iron plated and don't easily get chewed up by solder. Still, SN62 solder is already partially saturated, so it doesn't do much 'scavenging' of platings or tips.
