If you exceed the 150ma the driver chip will give out the magic smoke, not the board 
traces.  I know from experience.

the signal from your radio equipment and gave a 12v DC PWM output meant to
control high amp relays.  You are however telling me this isn't true?
Correct, the Mini does not do PWM.

magnetic coil type relays like they teach you about in early electronics
courses and not solid state ones, wouldn't they NOT be able to cycle fast
enough for PWM applications?  Don't they have a maximum trigger frequency
some what decided by the weight of the switch mechanism they use?  Is this
maximum frequency listed on their spec sheets?

If you try to PWM a mechanical relay I would imagine you would soon destroy it due 
to arcing at the contacts.
