Hi Jason,

You might want to look at recent papers from Atotech. They basically say that Ni/Pd?Au is much better, compared to a regular ENIG and helps eliminate BP.

regards,

Vladimir

Hello all,

after a short hiatus, I'm back.

I have a question - Can the Black Pad Defect be present if using NiPdAu? Can
the palladium prevent black pad?
