A method for etching of copper-containing factory do etching system thick as well as to carry out the method

摘要

copper workpieces, in particular kupferkaschierte pcb in an alkaline caustic, the active component of copper tetrammin complex contains, etched. after the etching, the workpieces with an essentially neutral fluid flushed, a ansatzlu00f6sung of the regeneration of the u00e4tzmittels regnerationssalzes is necessary.this regenerationssalz contains essentially ammonium and chloride ions. in a regenerationsanlage which is connected with the u00e4tzmaschine, the caustic to adjust the correct ph value with ammoniakgas and, on the other, the clearing process of neutral ansatzlu00f6sung transferred.
