If, in 10 minutes, 10 mils or .010" was removed from one side of the panel the etch rate is 1 M/S/M determined as shown below: E= S/T = mils removed/side = 10 Time 10 = 1 Mil/Side/Minute or 1 M/S/M The time of immersion to remove metal to a given depth can now be determined according to the formula. T = S E
