Abstract
PURPOSE: To enable the accurate control of an etchant concentration in a damping- water, by arranging a sensor for the electric conductivity of the damping-water in a mixing tank, and operating an etchant pump on the basis of a signal from the sensor to feed the etchant into the mixing tank.
CONSTITUTION: Water is supplied into the mixing tank 12 so as to keep the surface of the water at a predetermined level. On the other hand, a controlled amount of the etchant is supplied to the tank 12, so that the damping-water in the mixing tank 1 is kept at a predetermined etchant concentration. The control of the etchant feed amount is done with a sensor 42 for the electric conductivity of the damping-water. The control of the etchant concentration can be done more accurately, owing to the measurement of the electric conductivity instead of a pH value as in a conventional manner.
