Whatever you do , if any QA mgr will suggest you PENCIL ERASERS ; desist ,
go to archives ; we've had a discussion on this bad habit with Dave Hillman
not so long ago .

This is the case of cure worst than illness , address the process .

Subject: [TN] stain&gold plating



 I am looking for suggestions on "How to remove a stain on gold surface and
why does a stain happen on gold surface after plating?"

 In electroless Ni/immersion Au plating, I have found many stain problems
after plating. Threre are varied shapes of stains such as a spot, a line,
and an irregulare shpae.

 Anyone who can suggest a better idea?

 thank you!
