We are using it for mixed technology boards, that have pad spacings >1mm
only, with good results. Surprisingly, the pad to pad planarity actually
looks better than the typical Pb HASL.  The vendor we are using is
Advanced Circuits.

For years we knew and loved Pb HASL.  With the requirements of RoHS HASL
took a back seat.  Has L-F HASL had the kinks worked out so it is
becoming a main stream process?  If so, who is doing it and what is the
performance of the process?  Is it being used for SMT?

Thanks in advance,

Phil Nutting
