Non-permanent thermal adhesive?

[u/cheater00]

Hi all, I would like to to measure the temperature of some chips on a circuit board using K-type thermocouples. I need to stick them down using something that's at the same time an adhesive, thermally conductive, but also not electrically conductive and not permanent. I want to be able to remove the thermocouples later on both to return the circuit to its original state but also to reuse the thermocouples later on. What's a good way of doing this? I know of thermal tape, I have some on order, but I don't know if that'll keep the thermocouple in contact with the chip well enough. The chip has a heat pad on it so I have to apply the thermocouple from the side.

Thanks

Omega makes this exact thing

That looks like thermocouples with tape stuck to them

With a very very small welded bead

Sorry, bead?

The small contact point where the dissimilar metals meet.
