ABSTRACT:
A carrier for circuit boards comprises an open top box and a frame in the box. The frame is formed of four members--two sides and two ends which can be assembled to give predetermined variable spacing between the sides. Channel members clip to the inner surfaces of the sides. Box and frame are of metal, and the channel members can be of electrically conductive plastic. Metal lids can be provided. Boards are protected against static discharge damage and against dust and dirt. The top edge of the box has a rim into which the bottom of another box fits, for stacking. Electrically conductive foam material is placed on the bottom and at the sides to provide shock absorption.
