Abstract
A box-like package or container for electrostatic discharge susceptible devices such as contained on printed circuit boards or the like, wherein the container is formed of electrically surface and volume conductive paperboard or clipboard having surface resistance in the range of about 10.sup.3 -10.sup.9 ohms per square, forming a rapid box, overwrapped with electrically surface and volume conductive paper having surface resistance in the range of about 10.sup.3 -10.sup.5 ohms per square, and provided with a thermoformed plastic insert filler formed of anti-static plastic material providing parallel ribs arranged in vertical planes and defining grooves or slots for receiving and positioning the edges of the printed circuit boards or planiform ESD susceptible devices to be packaged therein. The resistance properties along the exterior of the container and the parallel resistance effect of the conductive paper and conductive paperboard are such that during charge redistribution when a highly charged object approaches near the container, the path of least resistance is around the walls of the container and not through the ESD susceptible devices packaged therein.
