I've designed hundreds of boards and never had a problem with silkscreen or soldermask related to conductivity. I seriously doubt any reputable PCB manufacturer would use a mask or ink that would be the least bit conductive.
I will say most of my designs were sub 50 volts. I never specified an ink manufacturer or specific brand, but I specified plenty of different specific solder masks. Ink was always left up to the supplier. On Saturday, September 17, 2022 at 11:00:01 AM UTC-5 Paolo Cravero wrote: > Hello. > > 2. Spacing for higher voltages.
