We are about to start using immersion tin PWBs (white tin) ,  the boards we
currently use are HASL and OSP. Are there any changes with the SMT process,
component termination finish or reflow process when white tin boards are used. I
know that white tin provides a better pad finish than HASL, similar to OSP, but
wihout the organic coating.  Any comments.


Any iformation would be appreciated.
