It’s a more affordable option than ENIG, and it is also RoHS-compliant. A typical thickness for Immersion Silver is 4-12u”. Due to the way copper and silver interact, they eventually diffuse into one another. hill \u0026 harbor east greenwichWitryna1 Answer. Sorted by: 8. I think it all comes down to corrosion, the flatness of the finish and cost. HASL isn't flat so you can rule this out for fine pitch ICs or BGA, the gold over nickel ENIG is as flat as it gets and the gold surface is the least reactive so won't really corrode and last for years on the shelf. smart agm clariosWitrynaThis specification sets requirements based on performance criteria for the use of Immersion Silver (IAg) as a surface finish for printed circuit boards.
