Hi Ken, Our product is consumer, although our product is sold on it's reliability. We run a low volume high mix throughput. Any ideas on timescale for the Ag leaching? Sounds like it could be a safer bet to use Imm Sn boards with the Sn/Cu/Ni bar w

In addition to your concerns about leaching, why aren't you concerned about: * Tin whiskers * Total absence of in use reliability information about no-lead, especially given that creep is significantly different between SnPb and no-leads. While they

We are concerned about the issues you mentioned and more, however we have no option but to change over due to legislation. A high percentage of our market share is in Europe and Japan, who of course have already embraced the no-lead change. We simply

Jacqueline, Asuming you mean immersion silver: Advantages - Very flat finish compared to HASL, more easily solderable than bare copper with OSP and more process tolerant than this in our experience, reasonable shelf life, cheaper than immersion gol
