Abstract
Disclosed is a transfer container for carrying circuit panels in and between substantially contaminant free environments. The walls of the transfer container are fabricated out of substantially particulate free, unfilled polymers, such as polycarbonate. One of the end walls is an access wall. The access wall has an opening surrounded by a ferromagnetic gasket. This gasketed opening is adapted to receive a ferromagnetic door panel. The side walls, and the top and bottom walls may extend beyond the access wall, with the ends of said walls defining a plane, so that the access wall is recessed with respect to the plane defined by the said extensions. Each of the side walls have co-planar bracket pairs for holding circuit panels. Either one of, or preferably both brackets of a bracket pair have pyramidal or conical positioning pins. These pins extend upwardly from the brackets and are adapted to receive and hold a workpiece in place.
