ABSTRACT:
A apparatus and method of interconnecting printed circuit boards in an electronic system inside a card cage. The apparatus includes a companion printed circuit board that connects to the main printed circuit board through a first electrical connector, the companion card providing at least one electrical path to a second connector. This second connector connects to the back plane of the card cage, with the back plane providing at least one electrical connection from the second connector to another electrical connector which connects to another companion card connected to the back plane. This method of interconnection avoids requiring flexible cable interconnections, thereby providing a cleaner layout of the electronic system, allowing easy insertion and removal of the main printed circuit boards as well as the companion cards, and providing excellent noise shielding.
