This condition has been discussed on numerous occasions in this forum. Please do a search in the archives. Anyway, the manufacturing industry has been using lead free parts for at least ten years with lead paste. It is the other way around that is

two ways to attach a thermocouple first with hig temperature alloy (for example Sn Pb90) it's not very easy to inclose the thermocouple in the solder because the wetability of the thermocouple is awfull. the second one: attach the wire of the thermoc

Where are people getting their high temp solder? I've found it before, but the price and minimum quantities were ridiculous.
