i wanna punch rohs in the face until all its stupid solder whiskers fall off
Hello,
I do not think that you really want to have cadmium solder.
During soldering cadmium solder gives very poisonous vapours.
Btw. LT AN86 speaks of 60% Cd + 40% Sn.
With best regards

oh shit, i did not realize cadmium boiled at 800c, i assume it gives a fair bit more vapor then lead (boils at 1600c).
the vapor pressure at soldering temperatures is enough to make working with it fairly toxic? sounds like it should be done under a fume hood or outside with a fan.. heh glad i caught that
http://www.powerstream.com/z/vapor-press1.pngooo, kinda bad, 10^-2 torr @ 300c, compare to lead and tin.. which have > 10^-8
certainly don't wanna do that indoors!
whats the working temperature of the solder?
and so long you are not an idiot about it I think it could be done safely. i would feel way more comfortable with cadmium solders (working with or manufacturing) then say, driving a car down the street, or going for a walk around my block.
you are in control of your own safety here. it would be one of the safer parts of my day.
compared to the amount of times I had a elevated heart rate from a bad driver to the amount of times I poisoned myself with heavy metals... hmm.. no contest
the only dangerous part of this would be running the electronics and a part running hot, possibly slowly vaporizing cadmium. this is where the danger is. might be worth while to put some thermal fuses on that circuit board! I would not want it running at too much more then room temperature. This could be considered if you have a thermally stabilized voltage reference soldered down with cadmium solder.
*in all likely hood though, you should probably focus your efforts on staying away from cigarette smoke if you are scared of Cd
