Anti-Pollution Measures on PCB Fabrication

This Gold Phoenix PCB Knowledge Center article covers anti-pollution measures for PCB fabrication, including wastewater, exhaust gas and waste residue control, 24-hour monitoring, 60% water reuse, and zero Cu-Etchant discharge.

Nowadays, the pollution from PCB fabrication has aroused great public attention. The environmental pollution of PCB fabrication is mainly in the forms of wastewater, exhaust gas, waste residue and so on. The pollution in China becomes more and more serious with the development of technology. In the future, the PCB fabrication will gradually move towards clean production and sustainable development. In order to achieve the goal, besides the attention from government and relevant industry, necessary feasible anti-pollution measures are also very important and stricter enforcement of the inspector is needed. Here are some suggestions on anti-pollution measures of PCB fabrication.

Firstly, the government must establish relevant laws and regulations to guide and control enterprise behavior, so as to save resources and improve resource utilization and reuse rate. Secondly, the PCB corporations that are not equipped with wastewater treatment facilities or equipped with unqualified wastewater treatment facilities should not continue PCB fabrication any longer, completely changing the situation of observing the law at high cost and breaking the law at low cost. Wastewater outfalls of the wastewater treatment of PCB enterprises should be subject to 24 hours of continuous automatic monitoring and recording. Thirdly, the newly built and extended PCB enterprises should be equipped with waste treatment facilities, especially circulating water treatment systems for the wastewater from PCB production process with a reuse rate of at least 60%, zero discharge of PCB Cu-Etchant and harmless emission of exhaust gas. Fourthly, the PCB Cu-Etchant should be sent to a specialized treatment plant so as to eliminate secondary pollution. Fifthly, the government should overcome local protectionism and make sure law enforcement is honest and fair.

As long as the relevant government departments and PCB related industries cling together and formulate measures and systems in line with the national conditions of PCB industry development in China, the pollution caused by PCB fabrication will go down substantially, even to meet the clean production requirement for sustainable development. For PCB fabrication, improving waste treatment measures and supporting clean-production practices are important parts of pursuing this goal.
