Actually that's a real number, the calculated thickness based on the conductivity spec of the grease. = 3.26µm

Assuming a simplified picture of uniform TIM layer and no contact resistance(TIM/Cu).
The usual picture is of TIM filling voids and then including Cu/Cu and TIM/Cu contact resistance
Have no authoritative links to hand (long time since looked at - put on hold - a can of worms)

Yes interferometry and load cell data would be useful but wouldn't expect a simple interpretation.

God, am struggling with the sheer volume produced so far in the Excels.
Converting to beermat format is a challenge.
