A miniature PWB with features that incorporate the required circuitry changes and component footprints, which has been enhanced with micro-castellations such as those found on ceramic surface mount packages. The miniature PWB is mounted on the circuit board using techniques well known in the art. This combination of technologies provides an adaptable, durable interconnect methodology, which allows for circuit and part changes without changing the layout of the base printed wiring board.

This invention provides fault tolerant capability for a Versa Module Eurocards backplane system design for high reliability applications. An approach of connecting two independent backplanes together electrically, but providing isolation capabilities in the event of a failure was developed. The electrical connection or integrated bridge design provides a virtual connection between the two VME backplanes that is transparent to the end user. The integrated virtual VMEbus design provides a low latency, high bandwidth interconnect between modules whether located on the same local bus or the electrically isolateable bus. This dual-VME fault tolerant backplane design eliminates complete system failures due to single event failures.
