What happens if our board is assembled and fails testing because one or more chips are bad? Does Avalon warranty the chips, so that they can be immediately replaced? Should I order a couple extra chips just in case?
What happens if 1/16 chips are bad on the board -- will it hash at 15/16 capacity, or not work at all?
My EE informed me that the fail rate of chips or board is pessimisticly 15% so yes it would be a good idea.
