One main disadvantage of HASL is too much hassle to use
HASL. One good advantage is every board shop can do
HASL.  HASL-free boards are the way to go if you want
to print fine-pitch or bga devices, or require warp-free pcb's.

Hello,  Please refresh my memory ... what are the
advantages/disadvantages
of HASL over other processes?  Specifically, why would a
Customer direct a
PWB supplier that HASL is not to be used ...?
