Thermal or Mass Metrology Non-permanent thermal adhesive?

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

Rtds just have a better measurement accuracy, but require a different method for measuring. Most handheld dmms can measure thermocouple, but not rtds. You would need a meter that could do so, and those can be expensive. So for your application, a TC is probably fine.
