Abstract:
1. A method for energizing and cooling a circuit card coupled to a backplane in an avionics device used in an aircraft, while preventing signals other than electrical power from being conveyed between the circuit card and a slot in the backplane that is electrically coupled to the circuit card, comprising: (a) eliminating electrical contact between conductors in the slot and a circuit on the circuit card, except specific conductors in the slot that provide electrical power required to energize the circuit card, wherein the conductors are spaced-apart longitudinally within the slot, and the slot extends longitudinally in alignment with a footer area of the circuit card on which electrical traces are disposed; (b) coupling the electrical traces on the footer area of the circuit card to the specific conductors in the slot; (c) employing cooling provided in the avionics device to cool the circuit card; and (d) conveying one or more signals between the circuit card and an external bus, device, system, or network, without using the backplane of the avionics device.
