Cabinet or box or receiving device for printed circuit boards and a method in order to avoid sharp pulse peaks in the signal applied to the printed circuit board

摘要

A cage apparatus for receiving printed circuit boards which permits an electrical potential to be directed across the printed circuit boards and a method for preventing the development of sharp spikes in the circuit signal applied to said printed circuit boards are provided. A first and second array of mounting guides are mounted in the cage apparatus to receive the printed circuit boards. The second array of mounting guides is electrically conductive and an electrical potential is directed across said second array. The printed circuit board is inserted in the cage apparatus and contacts the second array of mounting guides before a circuit signal is applied. Thus an electrical potential is directed across the printed circuit board which prevents the development of sharp spikes when the circuit signal is thereafter applied to said printed circuit board.
