Hello, Has anyone had issues with voiding while using Imm Silver PCB finish. Does thickness of silver, contamination of the plating bath or other factors if you come point out cause voids due to the plating.

We had one product that used immersion silver plating. There were a couple of instances where we saw tarnishing, and elemental analysis confirmed the presence of sulfur. These boards did have the anti-tarnish sheets between boards, but somehow they

I have heard that there are problems using immersion gold on PCBs when working with BGAs. Is this correct? Is white tin more suitable?

Where could I find more information regarding the double sided reflow and flux problems with white tin?

I read it in Florida Cir-teks own literature. http://www.florida cirtek.com

do you mean microvoids or macrovoids??

Yes it does seem like a plating issue and analysis is being done. Thank you for your inputs.

There's a lots comparisons like this on the web. Here's one: Westwood Associates said on 8/12/2003: ||HASL||OSP||ENIG||Pd||Tin||Silver Flat||no||yes||yes||yes||yes||yes Solderjoint||Cu-Sn||Cu-Sn||Ni-Sn||Ni-Sn||Cu-Sn||Cu-Sn Contact||E-test, ICT||no|

First, we expect voiding in imm silver to be similar to ENIG. We expect more voiding in OSP than other common solderability protection. Second, choosing a solder paste, which does not contain resins and activators that decompose at higher temperatu
