So far this year, we have had so many discussions of the various types of metal thermal interface materials, their thermal conductivity benefits, their thermal test performance and the various applications they fit into, that I thought it was about time to bring the conversation back to the basics.
What types of thermal interface materials are available?
There are no shortage of thermal interface materials out there. Among others, there are various possibilities such as:
1) Thermal Greases
2) Metal Filled Thermal Greases
3) Polymer Phase Change Thermal Interface Materials
4) Thermal Pads
Each of these have their benefits and are suited for niche applications, but most high power/high heat applications are best suited with metal TIMs for their superior reliability and thermal resistance benefits.
