Good Morning All:



Might I ask for some guidance from you all..



In determining a surface coating a conflict has arisen between choosing Gold
immersion vs. Silver immersion as the

choice. The application is for boards that are used in shipboard electronics
(non military) but they are protected from the external environment.



My question is which is the more appropriate coating?

Technically, the gold has always worked from the PCB fab and assembly end
with success with a controlled cost of ownership.

The silver however is one that causes concern.



Any suggestions would be appreciated.



Best Regards,
