I have another question: Does the slope of the conveyor is an important parameter in the solder joint quality? What is the standard in degree? Does that parameter can resolve my problem of partial fulling hole (between 50 and 75%)?

Hi Greg, Is anyone logging the errors at QC/touch up stage so they can feed them straight back to SMT and fix them? (i.e. skipped components, poor paste coverage etc) Obviously the faster you spot an error the cheaper it will be for you. Cheers,

Also try boosting the bottom zones up to get extra heat in. Now try this at lead free temperatures & watch them go pop as the air inside expands & vents at the base. O to be in America & be free of our wonderful european decision makers.

Rapid heating of solder caused solder underneath surface to expand and become pressurized. Check to see if power cycles on and off during warm up. A slower rate of of climb should help.

Click on OnBoard Forum under electronics forum. The last on board forum was by a guy who specializes in what you ask about. The company is Eagle Eyed One.

Precisely why I run like hell at the sight of a salesman. Though some are actually pretty knowledgeable engineers (these folks are not the cookie-cutter catalog pushing guys).

This phenomenon is caused by a high amount of halogens (Cl, Br etc.) used in the flux activators or in the flux surfactants. We've seen effects creating all colors of the rainbow. Changing to No-Clean (halide-free) will eliminate this color effect.
