Scott, Year ago we used Tac Pac with a spray accelerator. Just place a dab of glue where you want it, insert the thermocouple, then spray it with the accelerator and it would instantly harden. To remove, we used some kind of solvent (acetone?). Just a drop would start to soften the glue and within 30 seconds you could pull the thermocouple out for re-use.
I don't recall the product numbers but a little research should find them easy enough. I think it was something like Loctite 444 adhesive with accelerator kit. The accelerator was 7452 and came either in a small spray can or in a bottle. There are probably new formulas today that work just as good. Some glue the thermocouple up slightly from the end and then use thermal paste on the end. It is messy and we didn't really see much difference in our test results.

Currently I looked at an SMPS that is operating at a temperature of 120 degC under an ambient temperature of 20 degC. The tape seems not very reliable and rigid enough for long period of testing. Is there any other more suitable means to attach the thermocouple to such high temperature point of interest? The spec quotes the max temperature of 150 degC. Is it normal for the rectifier to have such high operating temperature?
