Abstract
An electronic circuit card has a metal case including top and bottom surfaces connected by first and second sidewalls and a rear wall. The case has an interior chamber and an opening at one end. A substrate is positioned in the interior chamber and a connector attached to the substrate and case so as to cover the opening. A metal spring is attached to the substrate in contact with a ground conductor on the substrate. The spring contacts the top and bottom surfaces of the case to support the substrate and to couple the case to the ground conductor. The case provides protection from electrostatic discharge and radio frequency interference and is capable of receiving substrates having different sizes or shapes or different arrangements of mounted electronic components.
