The Heatsink feet are 0.090" off the surface of the heatsink. the Pi Zero 2017 has CPU about 0.050 and the copper pad was 0.030 think.. so a film of Heatsink compound of 0.005 per side will do it. THe Bluetooth was super tiny, and only 0.010 off the board. so i doubled up the thicker heat sink compound and let it rip. if it overheats, I'll slip in some copper strip between.
