Received April 21, 2004 Abstract — The aim of this experimental study was to minimize the input of lead and tin ions and fluoboric acid into the waste water from the electroplating line, where the printed circuit boards and other parts of electronic devices are plated with tin-lead alloy. For this purpose, after unloading the parts from the plating tank, they were rinsed in the reclaim tank, from which the aforementioned ions were removed with a reclaim immersed elec-trochemical module (IEM).
