Before fixing the problem I would make certain there is one. Have you performed any evaluations on the solderability of the boards in their present state? You may find the solderability to be acceptable.

Best regards

  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.
