You're not suggesting this doesn't work, are you ?

Yep, works great especially if the photo is in black and white.

What, the blacks get blakker and the whites get... well, you know....?

Has anybody experimented with listening in a coldroom / industrial freezer?
Think of the tweak possibilities...
Perhaps soldering at sub-zero temperatures (good luck with that) might be the answer. Or maybe using solder with a melting point below zero which mandates operation in cold conditions to avoid the circuit falling apart.

Oh the opportunities for 'scientific research' !

The resistance of any good soldered joint is very low. The resistance of a dry joint is all over the place and unstable. Traditional tin/lead is still the best way to avoid dry joints and as a bonus, the lower melting point makes component damage much less likely.

63/37 all the way. Only exception would be when the components to be soldered contain silver plating, at which point I use Cardas Quad Eutectic. Might be filled with a bit of marketing, but it really does wet beautifully and even smells pretty good as a bonus. But the leaded kind, still.

post15 lnk:
Can anyone see where it tells us if this quad is a eutectic?
or it's freezing temperature?

Found it.
sn100c is not a eutectic.
Melting point stated as 228C
That's 44C, 79F degrees higher than 63/37 eutectic.
I have not found the pasty range (melted to frozen range). Maybe they are afraid to tell us !

Ime tin/silver sounds really good, lead/tin/silver sounds really bad.
No way can you hear differences between solder joints...

Joints? Hell, I remember when IAR introduced their Wonder Solder. Someone purported hearing a huge difference after they'd reflowed just ONE solder joint in the circuit with it.
