Hello davef - could it be you are confusing low thermal emf (Seebeck coefficient) with low temperature solder ? I am looking after solder wire and paste with low Seebeck coefficient - cadmium based alloy was OK but banned in europe due to RoHs direct

Hello - I am looking for a source to supply low thermal EMF solder - can anyone provide pointers ? In the past a cadmium - lead alloy was used for this, but these are banned (RoHs) ... - the aim is to minimize thermo-couples on a very sensitive 4 lay

Hello Michel...this might be a bit of a battle finding the low thermal EMF material that you are looking for. The first one that comes to my mind is Bismuth Selenium Telluride, with either a nickel or cobalt doping agent. Silver went away from this

What is the product for? If you share more information maybe there is another way of dealing with the issue, like removal of the joints by a different circuit design. sarason

I've never used SAC405. Not for nothing ... Other low temperature solder alloys that you should consider are: * Sn42/Bi58 [138*C]: Alloy for low temperature applications. Attention should be paid to potential embrittlement issues and poor thermal fa

Either the extra current draw to overcome inertia on the motor start up, or back EMF from the motor?

Just curious if anyone has ever used an EMF meter? I have used a static field meter but that is quite different. I have had hearing aids that had a switch that switched from an audio mike to a telecoil that would pick up the EMF from the phone speake
