Dear all, Recently we encountered some functionality failure when using lead-free component(Sn99.3/Cu0.7)at SnPb(Sn63Pb37) wave soldering process. Can lead-free component use at non-lead free process? Any input/idea are much appreciated. Rgds

Joseph, We have all been using lead free components for some time. Many passive already have a Pb free plating and we have not seen catastophic failures on them. From the information I have seen, I think this should be OK (with the exception of BGA'

Hi Joseph, It's difficult to troubleshoot if the defect is unknown, but I agree with Chris The majority of components are already lead-free and only 17% of the worldwide electronics industry switched to lead-free wave and/or paste so the majority o

Dear Patrick, Unfortunately we do not know what exactly the failure as our customer refuse to reveal to us. From visual inspection the solder joints are smooth and shiny as per IPC-A-610 requirements. The component supplier (IR) commended that they

Interesting, Gary. Try this: 1 Assess candidate solders by reviewing J-STD-006 (http://canfieldmetals.com/j-std006.htm) to determine solder formulations that have liquidous temperatures in the desired range. 2 Request recommended profiles from supp
