ABSTRACT:
A work station comprising a portable platform defining a work area for soldering and desoldering operations for electrical/electronic components with fume removal and reduced build-up of static electricity by providing a conductive surface in the work area connected to a ground and an air extraction plenum on the back side of the platform which communicates fumes from the work area to a vent. The fan communicates with the air extraction plenum to induce a negative pressure around a face side of the plenum for moving air and fumes through intake slots into the plenum. Nozzles mounted on a front side of the platform direct low pressure air flowing at a rate of one to four cubic feet per minute across the work station towards to the facing side of the plenum. A method of removing solder fumes is disclosed.
