Juan:  You may want to consider cleaning/deoxidizing existing silver, rather than re-plating.
Much easier/cheaper.

Subject: [TN] IAg PCBs. Re-plating?
To: [log in to unmask]

Hello,

I have a couple of questions for the PCBs specialist people.

We have a high quantity of boards plated with IAg. Most of them were 
manufactured before 2008. The questions are:

Is it possible to re-activate or re-plate the boards with the same finishing 
(IAg)? Risks?

Is it possible to remove the IAg and then to re-plate them with ENIG? Risks?

Thank you.
