[volt-nuts] Thermal EMF of common solder

Hello All.

I measured the thermal EMF of two common solder, the lead free
Sn96.5/Ag3/Cu0.5 and the old Sn60/Pb40.
I have ordered a spool of Sn96/Ag4 (the recommended low-thermal-EMF replacement
for cadmium based one) and I will post the result for this too.
I could probably find also Sn97/Ag3 and Sn97/Cu3 if it's reasonable to check
them; I accept suggestion on what else to try between the RoHS complaint ones.

Copper - Sn96.5/Ag3/Cu0.5 -> 3.4uV^C
Copper - Sn60/Pb40 -> 3.3uV^C

Best regards,
 Andrea Baldoni
