when choosing a thermal interface material (tim), most of the time we look at the datasheet and find the thermal impedance if it is a solid material, or the thermal conductivity if it is a grease. then, we calculate the thermal resistance and temperature rise with those numbers.
but, how do we know that a tim is performing as advertised? can we really tell if one tim will perform better than another, based on their specs?
