Looking for advice/products on ways to get heat out of a package and into an internal thermal plane. Will have electrically isolated thermal pads (going to an internal thermal plane) under the part.
Need a way to get good thermal contact between part bottom of part an these thermal pads. Have considered thermally conductive epoxies but have not found any with decent conductivity (all are ~<1.2W/mK). It is not clear on how a thermally conductive elastomer pad could be used in conjuction with assembly for vapor phase (what elastomer thickness would you use to avoid having the leads lift - and how do you maintain compression to assure good conductivity during soldering)?
Thanks,
