Has anyone had experience with the thermal conductivity of potting epoxies?
I have always been under the impression that when you pot a PCB assembly, you are trapping any heat generated on the board. I have recently been told that it is just the opposite when using the correct epoxy. In addition, you can add silica sand to achieve an even greater thermal conductivity. This goes against what I have been previously told, and I am looking for some additional professional opinions.
Thanks,
Mark
