| Looking for Cleaning solvent to claen missprinted PCB, that will be good for paste (CS) and glue (PS). | One that is easy to evaporate with out leaving | white powder around component leads on CS (when cleaning PS)

Are you using a water soluble paste? Older generations of water soluble paste are notorious for voiding. Some of the new generation water soluble fluxes allow a much wider process window.

We've found beading is not neccesarily the amount of paste but where it's applied. Trapping paste under components seems to be the culprit. On components where we couldn't reduce aperature size we simply moved it outward actually overprinting the p

Yano, imalookinat two vendor specification sheets that say your paste should sit around at "print temperature" for 1 to 6 hours before printing [er, words to that effect]. Werejallgit this 6 hours stuff from?

If it's inconsistent, reflow and part cleanliness is most likely OK. Check you stencil printing process. How do you perform post-print inspection? What is the stencil-life of your paste? How often is the stencil underwiped? Do you track paste additio
