英文摘要	This experiment was carried out in Wheat Island Qingdao which is characterized with a typical industrial polluted marine atmosphere environment. The atmosphere contains a large amount of Cl- and SO2. The corrosion mechanism of printed circuit boards ( PCBs) with an immersion silver surface finish (PCB-ImAg) in this phenomenon is still unknown. The corrosion behavior of PCB-ImAg is different under the influences of Cl-and SO2. Silver has strong resistance to Cl-, which mainly causes micro-hole corrosion. However, silver is sensitive to SO2. The corrosion degree can be accelerated in the environment containing Cl- and SO2. In this environment, the main corrosion products are oxides, sulfate and carbonate of silver and copper. The results summarized in this paper indicated that PCB-ImAg cannot be used in industrially polluted marine environment. Protective measures such as conformal coating are necessary to protect PCB-ImAg. (C) 2016 Published by Elsevier Ltd.
