Jeffrey,

Pd also dissolves into the joint, and again you are forming an intermetallic with the nickel.

Subject: EXTERNAL: [TN] ENEPIG Question?

Hi All,

Quick question, with an ENIG finish, I know the gold dissolves into the joint and we solder to the Ni.

But what about ENEPIG?  I'm assuming the Au will dissolve, but what happen with the Pd? Does it stay put or also dissolve into the joint?

Inquiring minds want to know.

Thanks,

-Jeffrey
