The water soluble flux residue is staying there because the rinsing temperature it may be too low. The flux needs about 130-140 degrees celcius to become soft. If you are using water soluble flux, as per IPC A 610 standards it needs to be remove comp

celsius or fahrenheit? I am not entirely familiar with the deeper details of HASL, but 130F-140F is adequate to clean many of the water-soluble fluxes used for component soldering.

I know our glue looks different when applied over different color solk screen. Maybe it's just an optical illusion?

i just thought that it because of difference thickness between the silkscreen and without silkscreen. if we apply the same pressure and dispense time to this two difference location, the glue size will be difference. location with silkscreen will rea

We had a supplier that put a [fuzzy and of variable height) line of ss between all chip R and C pads. Of course we were in low cost mode and had purchased a year's worth of boards.

Try using a solder like S03X7C from Koki, which uses cobalt to prolong the tip life & also a wire wool type dry wipe instead of a wet sponge.
