James 100 microinches is far beyond the capability of any immersion process. Once the host surface is coated by the attracted material there is no long a driving force between the host and the bath. In fact 10 microinches is normally very difficult. Perhaps the customer is looking for electroplated silver.

I am concerned putting the Silver over the NI as it may lift or peel. This is the first time I have had this kind of request. Have any of you well informed Tech Heads heard of this before??? ps. This customer also asked for OSP over the Silver over the NI. I KNOW that is not done.
