I have a question now that our company is beginning to use lead free
HASL as a solderability finish.  I am seeing a few (<5%) filled vias on
each board I examine.  Does anyone know if the manufacturer's are using
pure tin, and if they are has anyone looked at tin whiskers from HASL
filled vias?

Thanks,
mark
