Hi Scott, All, The tape tends to ensure that stresses on the thermocouple length won't lift the tip, working as a strain relief. We typically use a high-temperature fibreglass tape, with rubber thermosetting adhesive. Once it bonds, it doesn't soften again under warm temperature.
For the tip, we have previously used cyanoacrylate glue(thin formula), but recently at the request of regulatory agencies, we started using Loctite 384 thermally conductive adhesive to seal the tip. Seems to work well. I advise using only a small amount, just enough to cover the tip of the thermocouple. Not easy to remove, but we rarely reuse the tips anyways, preferring to re-weld them.

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?
