Plating on a high chrome surface  

June 20, 2008

We are in the pogo pin industry. Can we hard chrome a pure copper plate and then plate another layer of silver as we need a hard surface and yet to be able to have a high electricity flow ( Doing resistance testing on our pogo pin after a few thousand cycling). We experiencing high wear and tear on our current design plate (pure copper plated with Ni then Silver)

Hi, Mike. I don't know if that is practical or not. But what is very practical is electroless nickel (also very hard surface) followed by silver.
