WIENER Backplanes VME64x-430 J1/Jaux/J2

This monolitic WIENER J1/J2 backplane combines the VME64 Extensions style with the CERN V430 "nuclear VME" spec. It complies with VME64x specifications according to ANSI/VITA 1.1-1997 and 1.3-997 except the J0 connector which is replaced by the CERN V430 Jaux connector. 
The VME64x-430 is designed as a 10-layer board in strip-line technolgy and is available with 21 slots (full size).

The backplane is actively terminated and provides active automatic daisy chaining. On request the active automatic daisy chain is available compatible to the CBLT.

The  extended power layers and special current rails permit highest power distribution. The 21 slot monolithic J1/Jaux/J2 backplane has more than 300A current capability on 5V, which corresponds to 15A per slot (at 70°C). For power distribution and connection a flat sandwich-like structure of copper sheets is mounted on the back of the upper J1 area. All DC wiring from this high-current multi-layer structure to the power supply situated in the bottom is integrated into the backplane layout by using the space between the connector shrouds.
