Abstract: A method of applying a conformal coating to a printed circuit board and components attached thereto while leaving selected components attached thereto uncoated, comprises the steps of providing a printed circuit board having a multiplicity of components attached thereto, including selected components that are not to be coated; enclosing the selected components within conductive protective enclosures sized to enclose the selected components therein and thereby protect those components from the intrusion of conformal coating material, the enclosures having sufficient electrical conductivity to discharge electrostatic charges therefrom when one of the enclosures is contacted by an electrically conductive medium, thereby protecting the components attached to the printed circuit board from damage due to the discharge of electrostatic charges from the enclosures; applying a conformal coating to the printed circuit board, thereby conformal coating the enclosures and the components which are not protected by the encl

Abstract: A container for packaging electronic components which are susceptible to damage from electrostatic discharge or fields comprises a container made of paperboard or paper having an electrically conductive coating of electrostatic shielding material on the exterior surface thereof, and a coating of inorganic non-carbonaceous electrostatic dissipative material on the interior surface thereof. The electrically conductive coating preferably has an electrical surface resistivity of less than about 10.sup.5 ohms/square, and the inorganic, non-carbonaceous, electrostatic dissipative coating has an electrical surface resistivity of greater than about 10.sup.5 ohms/square. The electrostatic shielding material is preferably a carbonaceous material, and the non-carbonaceous, electrostatic dissipative material preferably comprises particles of amorphous silica or silica-containing material coated with antimony-doped tin oxide.

Abstract: A shipping tube for carrying static-sensitive electrical components (e.g., IC chips in DIP tubes) is provided to protect the electrical components from damage caused by the discharge of electro-static charges and/or moisture. In one embodiment, the shipping tube includes a hollow cylindrically-shaped body and a pair of electrically conductive end caps. The hollow cylindrical body includes a laminate of paperboard and layers of electrically conductive material on both the inner and outer surface of the paperboard. The electrically conductive end caps close the opposite ends of the hollow cylindrical body, and at least one of the end caps is removable. Further, at least one of the end caps makes conductive contact with the conductive material on both the inner and outer surfaces of the paperboard to provide a complete enveloping enclosure.

Abstract: A static protective laminated material suitable for releasably supporting thereupon static-sensitive components having leads, such as integrated circuits and the like, and for protecting such components from electrostatic charges comprises a layer of antistatic material through which the leads of the component being supported may penetrate, the antistatic material being adapted to control the rate of discharge of any static charges through the component leads as the leads are inserted into the laminated material, and a layer of conductive material into which the component leads projecting through the antistatic layer may penetrate and be releasably supported thereupon, the conductive material being adapted to establish a conductive path between the component leads, thereby preventing the discharge of static charges through the component.
