If you don't submerge the board, how do measure the level of contaminants on that portion of the board that is not submerged?
I suppose that you could only submerge a portion of the board and guess that portion represents the whole board. Of course, your area measurement would be only the area of that portion of the board that was submerged. Right? But then in order to maintain any meaningful process control, you'd need to control the volume of the liquid and the portion of the board that was submerged from lot-to-lot.
Yes, the liquid should be heated to 110 -120*F, as stated in the manual. Why, what's your thinking of this question? What are you trying to get at by asking it?
