Dear Joe, I am using for this purpose the LOCTITE 416 or 4204 INSTANT ADHESIVE (Loctite part # 41650 for 416) along with the correspondent ACCELERATOR LOCTITE 7452.(part # 18637). The thermocouple will be fixed to the location in less than 10 seconds. A very small quantity of adhesive is used,(it does not interfere with the measured values) and I found that it is the easiest was to keep in place the thermocouples. ( I am using thermocouples AWG30 and this adhesive provides a good contact for temperature up to 120 degrees Celsius). I did not have problems with the thermocouples for at least 48 hours. It is an insulating material as well.
I hope it helps. Respectfully yours, Constantin Constantin Bolintineanu P.Eng.

I'd appreciate any advice that could point to a higher performing tape/adhesive for such an application. Some of the IC's are quite small which doesn't leave much surface area for adhesion and I am using as many as 40 thermocouples per card.
