Fellow technetters, I do have two vertical HASL machine with the same
operating parameters but are producing different board appearance. One
machine is producing dull solder. I tried to lower the spray pressure to
produce thick solder thinking that dullness means thin solder but still
produced dull and rough solder surfaces. Any help?
