Hello Constantino ,
From the picture it appears the oxidation is on a PWB that's already
assembled. If this is the case I would not expect there to be a problem
with the connections as they were made prior to the oxidation. I'm
assuming the oxidation occurred during a thermal cycle in the assembly
process.
I would have a concern and would recommend testing the adhesion if a
conformal coating to this oxidized surface is required.
If I can be of further assistance please e-mail or call me.
Best Regards
