$\begingroup$ I would ask a PCB manufacturer with space experience. $\endgroup$– UweOct 12, 2020 at 10:25

$\begingroup$ Which environment? Low earth orbit where it's more protected from cosmic rays? Dusty surface of Mars or Luna? High-radiation Jupiter? ... $\endgroup$– Camille GoudeseuneOct 12, 2020 at 14:23

1$\begingroup$ It is interesting to know the most commonly used PCB coatings that are used in low and medium satellite orbits. But if you have information on the coatings used on geostationary satellites and interplanetary robotic vehicles, it would be great to share such information. In the countries of the post-Soviet space, urethane varnish is widespread, which is used to cover printed circuit boards (UR-231). I would like to know modern PCB coatings $\endgroup$– Artem LytovchenkoOct 13, 2020 at 6:14

$\begingroup$ Different but related: What mitigation procedures are in place in space systems to prevent whisker growth? and What are some common (but non-obvious) materials that are particularly unsuitable for spaceflight? $\endgroup$– uhohOct 17, 2020 at 10:08

$\begingroup$ I clarified the question. My first thought when I see PCB is Polychlorinated biphenyl, not printed circuit board. $\endgroup$– FredOct 17, 2020 at 20:20
