I believe what is going on is that some unscrupulous suppliers are using
their deep gold plating process to provide "flash gold" this will often
result in a thick gold coating. Once again the OEM needs perform a due
diligence inspection of the supplier and this should be followed by periodic
visits. This is expensive, but so defective circuits.
Best regards

Hi Lee,
However, I have been involved in issues of Au-embrittlement as a
consequence
of the electrolytic flash gold being plated too thick.
