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
