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

In the portion of Chapter 1 on Flip Chips, Ken Gallio states (1.8.2.1) "tin/lead solder leaching or dissolving gold and form metal compounds, called dendrites, that greatly reduce joint reliability because of high brittleness." What is the compositi

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
