Abstract

Plastic covers of a cartridge housing an electronic card such as a printed circuit board, for example, have their interiors and open end surfaces coated with a conductive paint to minimize electrostatic discharge (ESD) damage. Plastic covers 1 (Fig. 2) and 2, which are joined to each other by suitable means such as a tongue and groove connection, for example, have an electronic card such as a printed circuit board 3, for example, supported therein. The covers 1 and 2 and the printed circuit board 3 form a cartridge 4 for insertion into a receptacle in a host machine. The edge tab connector, which has its edge flush with the edges of the covers 1 and 2, of the printed circuit board 3 provides a conductive path to any electrostatic charge accumulated on a user's body when the user contacts the board 3.
