We are soldering a 8 pin TTL chip on to a CEM1 board that has a hot air level soldering. We use no clean soler paste for the reflow process. Now the customer wants us to clean since he is afraid of flux attracting the dust. We have some SMT LEDs that

I have experience to the Kester 2331 water soluble flux long time ago with white residue and it related to the solder masking. Check what kind of the solder mask and ask Kester to do the test for you. Rgds.

White residue remaining after cleaning circuit board assemblies can be caused by a variety of chemicals and reactions. Rosin and water-soluble fluxes, circuit board resins and epoxies, component materials and other contamination all contribute to this complex chemistry. This paper discusses many of the sources of the residues that seem to be an ever-increasing occurrence.

. The flux hardens and can be left on. The problem most people find with it is that it has a dark residue and when we used to use it on Printed circuit boards, the test folks would get upset because it would foul up their test fixtures and test pins
