Abstract
A circuit card has a conductive bracket (or frame or cover) which contacts the conductive frame (or cage or enclosure) of an assembly before the circuit can electrically connect to a bus or other circuit in the assembly. A high-value resistor between circuit ground and the bracket allows static charge to dissipate to frame ground harmlessly.
