Disclosed is an apparatus and method for processing electronic components in an ultrasonic bath. The apparatus includes a tray, which has a number of nests geometrically configured for the admission of the components. In one embodiment the tray is made of a polypropylene core which includes conductive carbon and glass beads as a filler. Plated over the core is a metallic sheath, which is actually formed of three layers of metal. The metal encapsulation of the core serves to appreciably reduce the amount of contaminants released by the tray during component processing. Additionally, the metallic sheath prevents static electricity from building up and damaging the components during processing, and provides added structural integrity to the polypropylene core at process temperatures which exceed the softening temperature of the core.
