Water wash cleaning with a deionized water rise is used for bare boards and assemblies [and probably components also, but we're not sure]. Look here for the basics: http://www.circuitree.com/CDA/ArticleInformation/features/BNP__Features__Item/0,2133

I know it is not easy to quantify zero. The biggest dilemma the no-residue technology is facing "disbelieve" The most accurate proof to the fact that all solids disapear under heat is TGA analysis. Test the no-residue in your facility under the rig

Patrick, can't you just post the data? I noticed it wasn't readily available on the web site. Russ

Patrick, I would like to try a sample of your product. Please forward me a link or email address for where I need to go to get one. That way I can see it perform myself. Thanks Josh

Thanks Josh, email your company name, address and phone No. to sales@no-residue.com and a sample will be send to you. Patrick

Grant & JDumont: You should not have this white residue on your wave soldered connections, using VOC flux [but you know that, anyhow]. Applying too much flux is the likely cause. Other possibilities are: * flux contamination * solder contamination

Hi Dave, its not the connections that have the white residue. It is the surface of the board. The whole thing turns a milky white color. I have pictures if anyone would like to see them... Josh

The only time I have ever had this happen was with un/not fully cured solder resist. Only shows up after wave. I believe that is because of the higher temp than reflow but don't know for sure. No help but what the hey Russ

Well how can I correct this? Would baking the board prior to any operations help? Is this an issue I should get the PCB manufacturer involved with, or something that is common and just live with it?

If you can rub it off, it's unlikely to be a solder mask problem. Try the "excess flux, flux contamination, solder contamination" angle.
