Hi, Thanks for the info. How clean can wave soldering get? We are looking at a carrier that masks off most of the board when we run it through the wave, so hopefully this works. Regards, Grant Blackmagic Design

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

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

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

Hi, We have the spray fluxer, and I will have a look for the manifold. The guys thought they had purged the system but it's worth checking. Regards, Grant Blackmagic Design
