The one caveat I would add about blasting boards with (clean) compressed

In particular: I'd be cautious about using compressed air to clean out
electronic equipment that's been stored in sheds, barns, or other
locations where there might be rodent activity. I've seen some pretty
grotty equipment donated to our ham club, which I thought might well
have been peed or pooped upon by rats and/or mice.

Hantavirus is no joke.

A vacuum, particularly one with a HEPA filter, would be safer than
compressed air (either indoors or outdoors).
