Fellow TechNetters:

   Are all LF solder fluxes created equal?   I often see m/b with more flux residue, dry-crusty-yellowish, accumulated around the solder joint.  Yet others are almost free of flux residue.   I do see that either solder form a glassy halo around the solder joint at the solder mask surface.   What are the Pros & Cons.   The solder flux residue is more pronounced on Filed return assemblies or those which have been subject to reliability testing, HALT, HASS, S&V & T/C

Victor,
