Abstract
Abstract A container (10) for longitudinally receiving a plurality of electrostatic sensitive electronic components (12) having a rigid, transparent, elongated channel (14) being open on at least one end. The channel (14) has a transparent, insulative layer (22) and a transparent conductive layer (24) at least partially transversely surrounding the electrostatic sensitive electronic components (24). Optionally, the interior surface of the channel 14 may contain an antistatic layer (27). Further optionally, the exterior surface of the container may contain a transparent protective layer (26).
