what about the blue ones ?

I have some heavily populated brown boards out of a marine navigation system that had gold fingers on them i wonder what grade those were

It has been explained to me all brown boards are low grade. cut the IC chips and gold finger off. Store it and save it thenn throw the board in with low grade. However you could ask some of the forum buyers. Myself I buy ALL brown boards as low grade. I cut the chips and such off as I said.
