Hi, We are using chip components with Silver Pladium coating and finding poor wetting. We are using the water wash solder paste with 2Ag and std. reflow profile. Any suggestion how ti improve the solder wetting for those components. Thanks,

I just got a report from MacDermid on Solder Mask Interface Attack Issue (SMIA) with Sterling Silver Process. Corrosive chemicals in the ImAg process get trapped under the soldermask edge and eat at the copper trace. They are experimenting with diffe

I think all silver on a bare board is Immersion. We are a bare board manufacturer and that is the only silver I'm aware of being used as a finish. What is the problem you are having?

It appears that the two different boards we are having issues with are the only imersion silver boards that we process. Anyone have simililar issues with imersion silver? Is Dave F. on vacation? I would be willing to consider input from moon man at

Sterling is a Mac Dermid [www.macprintedcircuits.com/final] product. They should be able to help make the distinction that you look to make.
