Abstract:With the rapid development of PCB electroplating industry, more and more attention has been paid to the environmental problems caused by electroplating, The waste water and sludge of PCB electroless copper plating contain heavy metal ions and copper pollutants, which are very harmful to human body and environment. The recycling of copper resources through the combination and collocation of existing technologies can not only reduce environmental pollution, but also increase benefits for enterprises. In this paper, the pollution analysis of PCB electroless copper plating process and the suggestion of pollution control are put forward for reference.
