Hi Paul,



Everything dissolves in everything but at different rates. So, Cu will be diffusing into solder ("dissolving") but VERY slow.

Subject: [TN] Copper Dissolution at 150°C



A quick question.



Can copper dissolution occur below the liquidous temperature of the solder?



My sense is no ... but I am not sure.



Sincerely,
