/diy/ - Do It Yourself

But how am I supposed to access the screws when they're underneath the PCB? Or do you mean tap the TO-220 tabs and screw into them from the underside of the heat-sink? Because that sounds like a nightmare of electrical isolation.

Also I'll need a really thin electrically insulating thermal transfer pad to clamp these onto to prevent shorts, not really sure where to get that. Assuming normal thermal grease won't keep insulating everything when I crank down the screws. Maybe the nano-diamond thermal compounds are sufficiently rigid and insulating?
