Hi, No clean mean is no need to clean. Of couse if you usin incompatibility solvent to clean, the white residue will appear. If cleaning is needed, source the suitable solvent and this always suggested by your solder paste supplier. regards

from my experience, no clean mean "difficult and cannot clean" Normally, you will observe white residue when cleaning it. You should study the flux in the no-clean solder cream before cleaning it. Or change no clean solder to clean type solder
