Abstract

The accessibility of computer signals associated with card-mounted components in a confined area is enhanced by physically relocating the selected card while maintaining the electrical integrity of components mounted thereon. This is done by mounting the cards singly or in pairs at the rear or pin side of the board using a test board for rerouting the signals.

Back Panel Element Connector

The accessibility of computer signals associated with card-mounted components in a confined area is enhanced by physically relocating the selected card while maintaining the electrical integrity of components mounted thereon. This is done by mounting the cards singly or in pairs at the rear or pin side of the board using a test board for rerouting the signals.

As shown in the figure, a series of cards A through G are normally mounted on a card 2. Another printed circuit board 3 is mounted at the pin side 4 of board
2. A fixture (not shown) retains both boards 2 and 3 and also permits relative movement of the test board 3 with respect to the board 2 under test. Board 3 includes rows of spring-loaded probes 5 (pogo pins) that engage and transfer the signals from those rows of pins associated with the sockets normally retaining cards E and F. Board 3 transposes and reroutes the signals from the spring- loaded probes to the proper connections in the sockets which retain the relocated cards E and F, identified in the relocated position as E' and F'. In the relocated position the cards are in substantially the same environment and are not subjected to the extended path with the possible increased interference and altered impedance that may be encountered in the elongated signal paths introduced when extenders are utilized.

Indexing board 3 with respect to board 2 permits the relocation and test of any of the cards, either singly or in pairs...
