Hello! I want to screw 4 thyristors to the anodized aluminum profile. As you know, the anode coating is non-conductive. On the other hand, thyristors have their heat sink connected internally with the thyristor anode. The electronics board is made in such a way that the anodes control the outputs and I cannot short them to a common one. Is it possible to screw these thyristors to the common profile without fear of a short circuit between the thyristor signals without mica / silicone washers, or to provide washers?
