Zusammenfassung:Applying solder flux using spray methods has become dominant in many electronics assembly applications, from standard wave soldering of printed circuit boards (PCBs) to selective fluxing of components and assemblies. Spray fluxing began in the late 1980s, when no-- dean fluxes first appeared as alternatives to the banned Freon for cleaning flux residues from PCBs. However, these new fluxes did not perform very well when applied by traditional foam or wave techniques.
