Abstract

The use of large hybrid circuit boards to package systems reduces or eliminates internal cables, increases system performance, and reduces overall system size. In so doing the product costs are reduced, and the system reliability and serviceability are enhanced. A large hybrid board, as proposed, would allow Thermal Conduction Modules (TCMs) and cards of other technologies to be mounted on the same circuit board. The figure shows an example of a large hybrid board which would accommodate a number of TCMs in excess of the current limit of nine and also provide for a number of more conventional circuit cards. If the figure represented a processor with its associated memory, there would be in excess of 1200 signals between the TCMs and the circuit cards.

Systems Packaging Using Large Hybrid Circuit Boards

The use of large hybrid circuit boards to package systems reduces or eliminates internal cables, increases system performance, and reduces overall system size. In so doing the product costs are reduced, and the system reliability and serviceability are enhanced. A large hybrid board, as proposed, would allow Thermal Conduction Modules (TCMs) and cards of other technologies to be mounted on the same circuit board. The figure shows an example of a large hybrid board which would accommodate a number of TCMs in excess of the current limit of nine and also provide for a number of more conventional circuit cards. If the figure represented a processor with its associated memory, there would be in excess of 1200 signals between the TCMs and the circuit cards. Other configurations are possible that would allow Processor, Main Store, Extended Store and Channels to be on the same hybrid board, in a sense, a complete system on one board with no cables.
