The APL Cleans Up

High-voltage or high-frequency applications can be intolerant of flux residues remaining on the assembled board surface and so will often be specified as a water wash solder paste assemblies. The recently installed APL Aquastorm 50 is most often configured for a deionized water wash process to clean such water soluble assemblies. This batch cleaner is however also capable of using various commercial cleaning formulations necessary for removing more tenacious No-clean paste residues. Such additional ‘No-clean’ paste wash operations are common in mission critical military/aerospace applications and used prior to component underfill or conformal coating.
