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.
