Default Insulating Pads

Simple question: how much do you trust insulating pads ? I mean would you mount on an exposed heatsink chip that carries 450 V ?

They usually work very well.

The only time I have had a problem is with swarf getting into the mix and that is disasterous for the amp. I now always do a multimeter check between drain and heatsink for shorts before powering up.

I had a bit of swarf once stuck in the insulator and couldnt see it, replacing the insulator cured the problem. It was definitely swarf because the multimeter measured a short.

Berquist silpad 400 (9mil) is rated at 4500 VAC breakdown voltage with excellent thermal conductivity. Quite expensive though. E
