Abstract
A fabrication clean room work station is portable and has a funnel-shaped cleaning area which is connected to a vacuum source through a bottom opening. The work station also has a perforated cover positioned across a top opening of the cleaning area to provide a work surface, a catch screen positioned across the bottom opening of the cleaning area to catch dropped parts, a funnel cover which slides over the cleaning area to enclose it, and a flexible tubing in communication with a port formed in the cleaning area. The port is positioned above the catch screen so that any parts vacuumed through the flexible tubing would be stopped by the catch screen. The vacuum source supplies vacuum at the work surface and at the flexible tubing. The vacuum at the flexible tubing is increased when the funnel cover is positioned above the cleaning area.
