Hi Richard:
When a PCB is rated 105C or 130C or whatever, what does that really mean?
Can I really operate a 130C rated board at a maximum surface temperature of
130C for years without being concerned about reliability or safety? Is there
a relationship between de-rating and

Basically, yes, though you may want to throw in a fudge factor to assuage
your caution/due diligence monkey.
FYI: The Maximum Operating Temperature (this is a normal operating condition
temperature) for a PWB is based on accelerated aging testing, and comparing
as received performance
