ABSTRACT:
An electrically grounded storage cabinet for electrical circuit board modules is provided with multiple rectangular arrays of brackets for receiving at least one pair of conductive rectangular shelves. The shelves are slidably adjustable in elevation relative to each other on the brackets. A circuit board module is received between registered grooves in the lower surface of one shelf and the upper surface of the other shelf in each pair. The modules are grounded through the shelves, supporting brackets, and cabinet walls to preclude damage to the modules from static electricity discharges and to provide a controlled discharge of any charge remaining in circuit board components after removal from service or any incoming charge from personnel or the environment.
