Dear Antonio
IF the leads are gold plated - the corrosion is due to porosity in the gold
and underlying Nickel.
What is the thickness of gold and nickel specified?
Your specification will have to correspond to the environment you will
subject it to.
Corrosion or Porosity test - IPC has a test procedure 2.3.24 - TM 650 and
also ASTM B-799. Take care not to conduct these tests if the room ambient is
> 55% RH.
