Unless, of course, you wish to vary Die-size and investigate these predictions.
Would like to see the continued use of an appropriately sized Flux -block.
Think gives the truest value for TIM resistance

Hmm, you want me to work.
The fluxblock will stay in the picture Les. Unless tests show that it is unviable. At this point my rough measurements show it agreeing with electrical input, but I will test a fluxblock with a third sensor to verify gradient linearity. I believe it is possible to quantify the shadowing effect and according my numbers, it's a small effect. (~0.1 deg C with 2 sensors @70W) I will want to get an exact number for this though.
I am planning to limit myself to two die sizes: 10x10mm and 12x12mm, with appropriate fluxblocks which are 12mm high, sensor spacing 10mm. In addition a die sensor 1mm below the surface, the die itself being 4-5mm deep before spreading to match the heater dimensions. Something like this:
At the moment I am wrapped up in the electronics side of things, and it is going to be a while before I am up and running. The metalwork I am leaving until the Data Aquisition side of things is done so I might change dimensions depending on input.
