The easy answer to your questions is yes to both.


Juan,



The easy answer to your questions is yes to both.



My questions back to you are:



Why would you want to re-activate or re-plate the boards?

Are you having difficulty soldering them?

Don't you like the looks of the two year old boards?



Regards,

George

Subject: [TN] IAg PCBs. Re-plating?



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.
