TIM Testing

[jlrii]

The current high end of TIM testing (http://www.electronics-cooling.com/html/2003_november_a2.html) .... Hadn't come across this B4 (from 2003) hopefully not a repost, Looks DAMN Expensive.

JEDEC = max tech + $$$$$$$$$$$$$$$$$
for us anyway

Would be nice for them to provide some numbers for common TIM materials to the common users.....To bad it ain' gonna happen.

huh ?
Inchoerent just did so

The only result I want to see is how much loss the TIM causes in transferring the heat. I believe I read Incoherent's results but not sure a answer was there? Might have missed the last part of the discussion though.

I glanced at it real quick, catching the highlights, and couldn't help but wonder if it would be possible to characterize a TIM based on the rate of temperature range. There are many allusions to this, including a reference to the heat capacity of the TIM material...

Must read some more.

I don't see how a dry joint can be used as any kind of reference point. I'd also like to see the cleaning method (that is, if they don't replace the blocks each time!).

I just meant it would be nice to see numbers from a rig that accurate as a reference.

No dis' intended for Incoherent, his work and atention to detail are far beond what most of us could hope to acheive, but mounting pressure / block alignment in a spring type setup could lead to inacuracies... i.e. If samples are taken for a series of mounts, and the mount is never absolutely perfect, the results will be scewed and a lower c/w will result.

I couldn't venture a guess as to how much accuracy is gained from the $$,$$$ investment involved in building such a rig, but it would be nice to see.
