Effects of Tarnished Silver Plating


I need help. One of my customers is trying to return RF connectors because they have tarnished. I'm trying to convince them that it shouldn't really affect the electrical performance in high power environments. Is this a valid argument ? What do you think ?

You don't have a chance. Take them back and find out how to provide what the customer wants.

What did customer specify as the requirement? Silver will naturally tarnish over a period of time depending on how these are stored. However, connectors could be cleaned and added a protection coating. As for the electrical properties, these are unlikely to degrade except for the surface contact resistance.
