Good info, thanks.
I'd just note that the failure (cracked solder joint) is not due to the current it carries, nor temperature changes from current. That's a classic "cold solder joint", which was defective the day it was made. It did not wet properly, and made it out the door with that crack, still making contact long enough to function, until eventually vibration and temperature changes caused micromotion and intermittent operation.
