Backplane VME430

The CERN V430 “nuclear VME” standard extends the traditional VME/VME64 bus by additional DC and signal lines provided on a 30-pin J-aux connector. The monolithic WIENER VME430 is designed as a 10-layer board in strip-line technology and is fully consistent with ANSI/VITA 1-1994 and IEEE-1014-1987 as well as CERN VME430 specifications. The backplane is actively terminated and provides automatic daisy chain either actively or mechanically (in connector, on request).

The extended power layers and special current rails permit highest power distribution. The 21 slot monolithic J1/J2 backplane has more than 300A current capability on 5V, which corresponds to 15A per slot (at 70°C). Optional the J2 can be equipped with 160pin 5-row connectors.

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.
