Maintain DI water to 18 Meg Ohms resistivity. You can go down as low as 2 Meg ohms, in a pinch, but I would caution on what type of board you are running if trying to clean on 2 Meg ohm. Anything that is running an RF or high frequency circuit could

Sorry, I went dyslectic of the doc numbers, but you get what I mean (I hope): * J-STD-001B was released October 1996 * J-STD-033A was released April 1999 Without belaboring the point further, J-STD-001C is current and contains references to J-STD-
