Hey Group,
I am trying to design a high voltage capacitor where the plates will be constructed out of layers of single sided FR4 or similar pcb material.
I anticipate voltages from 1,000 to 5,000 volts RF and I want to try to prevent arcing.
My question... are there certain types, colors or mixtures of solder mask that would have a higher dielectric strength to help prevent arcing?
thanks for any guidance

Generally speaking solder mask is not regarded as any form of insulation. It can have pinholes (not so likely nowadays) but can be easily damaged. If I was doing this I would look at thin plastic sheeting that could be put between the PCB to whatever it could arc to. This sheet is available at quite high withstand rates
