I try to use small sinks just try to get the board into the amp box...seems not quite possible especially if I may use 1 board per channel in the future...just hope that this board with remote sensing, I can get by with putting the board in the PSU box (with about 0.5 meter wires connecting) without too much negative...
The high voltage of itself is not a problem.
It's the accidental shorting of the copper backplate to anything at a different voltage that is the problem. Extra insulators cannot cure that.
The screwdriver tip will still span the gap from backplate to heatsink. The Finger can still touch the 200V.

Plastic devices are the best choice here.
Luvdunhill, what are you refering to - caps or insulators?
