The CPU component was considerably hotter than environmental temperature of course (even if idle 99.9% of the time). | |

But this depends on the actual solder alloy used. 100% Sn starts to change its modification already below +16°C, adding minimal Ag or Cu helps a lot. For military equipment which has to work at extreme low temperatures leaded solder is still used. | |
