The effects of SO2 and Cl- on the printed circuit boards with an immersion Ag surface finish (PCB-ImAg) are studied. The results of outdoor atmosphere experiments are compared to those of indoor simulated experiments. The results show that PCB-ImAg cannot be used in industrially polluted marine environment without any protective measures.
