Mine also.
And I miss Werner; he was one of a kind.

Subject: Re: [TN] immersion silver
If Werner were alive he would be reminding us that silver, like gold, is a contaminate in tin solder.
Early finishes, prior to 2005 or so, weren't good for multiple reflows. Some presumed it was too thin.
I believe the problem was the durability of the organic additives that retard oxidation of the silver.
Not perfect, but it is my preferred surface finish, but not too thick.

Hi All,
Why would someone choose thick immersion silver over thin? Are these different chemistries? Regards Steve Kelly
