Abstract of the Disclosure, An anti-static tray for holding semi-conductor devices and components, is formed by a flat sheet of metal for example aluminum with, a layer of electrically conducting foam material on one side. Terminal pins extending from the devices are pushed into the foam and securely, held. The devices are then protected from static charges which might be applied by persons removing devices as any static charge is bled off into the metal sheet. Legs can be formed by bending down short lengths of metal from the sheet, so that trays can be stacked without contact between a tray and devices and components mounted on the tray beneath. - 1 -
