Abstract

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.
