I am designing a PCB that has high voltage (DC) on it. It will be located on a CubeSat (so, space).
The PCB (HV-PCB) will receive the HV (3 kV max) from a DC-DC converter through a Coax cable; the purpose of this PCB is to filter the HV through an RC circuit and then distribute it using connectors and cable to 16 detectors (they are on another board, see below) to provide them with bias.
The HV-PCB will also host another filtering circuit for another HV (<300 V) and will also distribute it to the detector board using connectors and cables.
a) are there particular materials that I should consider for the PCB?
b) can the two circuits live together on the same HV-PCB? My guess is that the best thing to do is to have the components well separated (spatially) on the PCB.
c)in terms of components, is there a particular family of components that I should look into, that are suited for my application? (HV, space).
In general, do you have references (pdfs, youtube videos, tutorials, standards) that might be useful for the design of a HV PCB?
Thanks for the help!
EDIT: tried to be more specific with my questions; on the other hand, I still need to stay generic, since I am asking for some guidelines/suggestions. Hope it is good enough.
