I'd exercise some caution here.  You state that it's a RF PCB.
Depending upon the frequency, there may be a measurable electrical
difference between the two processes that may have an effect on the
electrical performance of the product.

Subject: [TN] Electrodeposited Silver vs. Immersion Silver

Good morning TechNet, 

 

One of our drawings for an RF PCB calls out "Silver Plate per QQ-S-365,
electrodeposited, Type I, 0.0003" thk."  The supplier that we are
getting quotes from says he can't do electrodeposit and wants to supply
immersion silver boards.

 

Are these two processes equivalent?  I searched the archives and cannot
find any references to ED silver.  Has immersion replaced this process?
(Our drawing is pretty old.)

 

The board material is Duroid 5880.  would this make a difference?

 

Thanks for your help!
