Re: TIM stability

I wonder if the same can be applied to the thermal material used for CPUs, which traditionally use silver-based or even ceramic materials to transfer the heat load.

TIM stability

Hi All,

 

Thank you very much for commenting, I am happy that you found the article interesting. My intention was indeed to raise awareness on the possible change of the TIM parameters in an application. If the stability of temperature sensitive parameters is a design goal, a highly stable TIM material should be selected, or perhaps the low thermal resistance should be sacrificed by not using TIM at all.

Changes in TIM

I was not aware that there was such a significant change in TIM performance over time.  I had erroneously assumed that this is relatively constant (which it is not).  As the article states, this effect can have a significant impact upon reliablity as the number of cycles increases and is an important consideration for product design for reliability.

Different TIM products and different TIM performance.

This is a useful and informative writeup. I had not considered all of those possible thermal interface materials, so that was educational as well. 

What was possibly beyond the scope of this article is a discussion of the mechanism of change in thermal conductivity of the interface. That information would lead ti a good deal od insite on the whole topic, and move us toward the realm of "expert."

Thanks for a good writeup.
