Hi Technetters,
        Anybody using immersion tin as a surface finish?  What are some of its
quirks?  We have a customer that wants us to use it, so we are going to
qualify it as soon as we can get some boards in from multiple suppliers.
 During the qual, I would like to know ahead of time what problems to
look for.  We are currently assuming it will be a drop in for our OSP
and immersion gold boards.  (We got rid of HASL a while ago because of
shorting on fine pitch is orders of magnitude high than gold).


                        Thanks
