Hi Dave - Just wondering why 10mm back from the contact point of the thermocouple? I prefer to use high-temp solder. However, whether you are using high-temp solder or conductive epoxy, the key to reliability is to remove as much of the old (low-temp, 63/37) solder that was already at the interconnect using solder wick or similar. Then attach the TC with either a small amount of conductive epoxy or flux and wire solder (ie: 10/90). Use a small amount of either and be sure that the welded end of the TC is in contact with the interconnect you are measuring. I will discuss this subject in the "On The Forefront"column in the April Circuits Assembly magazine. Phil Zarrow ITM, Inc.
