Hi Cheryl, There are some recommended maximum chloride levels at csl`s web page(www.residue.com) 4.5 micrograms per square inch for final assemblies processed with rosen fluxes 2.5 micrograms per square inch for final assemblies processed with low solids (no-clean) fluxes 4.5 -5.0 micrograms per square inch for final assemblies processed with water soluble fluxes <2.0 micrograms per square inch for a bare board(tin-lead coated) Rinsing water is one of the source in PWB manufacturing.
