Portable electric hot air rework tool for soldering and desoldering printed circuit assemblies

摘要: A portable electric hot air rework tool for directing a stream of turbulent through removable and replaceable nozzles with selectably sized orifice to predetermined size localized areas printed circuit assembly until temperature sufficient melt solder is achieved, thereby facilitating the soldering/desoldering components or parts mounted thereon. The apparatus essentially comprises work station having upper lower heat tubes, plenums, which blower-forced made by turbulators contra-pitched blades directed, an adjustable support grid supporting pc assembly, within directed three-position switch controlling flow in tubes. An alignment positional indicator aids precise location assembly. tubes are lined refractory cement electrical thermal insulation, while turbulators, blower electrically conductive connnected metal removal static electricity from stream. sensitive lacquer used detect when holding component has achieved desired at can be removed replaced. provided resistance heaters heating nozzle ceramic cement. sufficiently large as remain cool during operation supported
