Abstract

A separate connector 10 can be used to bring power to a printed circuit card 12 to eliminate the need of transmitting such power through the signal connectors 14. In a packaging system optimized for the distribution of logic signals to and from circuit cards 12, power is usually transmitted to the cards by way of the same connectors 14 that distribute the logic signals to such cards. This involves transmitting power to board 16 and then through the board to connector 14 and from the latter to card 12. The distribution method to get onto the board and then the card is not ideal from a power distribution point of view. It is a compromise in order to supply current and voltage through a package optimized for logic signals.

Printed Circuit Card Connector

A separate connector 10 can be used to bring power to a printed circuit card 12 to eliminate the need of transmitting such power through the signal connectors 14. In a packaging system optimized for the distribution of logic signals to and from circuit cards 12, power is usually transmitted to the cards by way of the same connectors 14 that distribute the logic signals to such cards. This involves transmitting power to board 16 and then through the board to connector 14 and from the latter to card 12. The distribution method to get onto the board and then the card is not ideal from a power distribution point of view. It is a compromise in order to supply current and voltage through a package optimized for logic signals. However in this method, the power is brought directly to the cards through an independent system of cables 18. These can be optimized to the requirements of power distribution in terms of reactance, resistance, noise immunity and other considerations.
