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.
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.
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."
Major changes are happening in the world of 3D printing and additive manufacturing materials, machines, and software. If the industry -- and the design engineers and OEMs it serves -- are to grow, all three areas must become much more tightly integrated.
Americans spent more than $60B on their pets in 2015. Folks are definitely spending their money on more than dog food. We’re spending on things like dog spas and fancy toys, and as you can imagine, the wearables market is becoming well represented here.
Time was when sports equipment was made only from common, everyday, low-tech materials. But now sports equipment has a new, high-tech ingredient that is helping players take their game to the next level.
