Elma Bustronic Corporation, an industry leading designer and manufacturer of high performance backplanes has 6U and 7U VME64x backplanes in over 30 slot sizes and hundreds of standard configurations.

Bustronic offers all of the common slot sizes for its 6U and 7U backplanes, which range from 2-21 slots. With various power, connection pin tail size, shroud, P0 connector, and other options there are hundreds of standard configurations available. The 7U backplanes have an extra 1U of height for extra power bugs to accommodate higher power requirements. In some configurations, this taller backplane acts as an air baffle to redirect the airflow path to aid cooling. In other chassis designs, the 6U height is required due to space restraints or airflow considerations.

The Bustronic VME64x backplanes come with power bugs for +5V, +3.3V, +/-12V, +/-V1, +/- V2, and GND. Compliant to ANSI/VITA 1.1-1997 VME extension standard and ANSI/VITA 1-1994, the VME64x line features a controlled-impedance stripline design. The backplanes have an active BUSGRANT, IACK daisy chain and optional stiffeners. The standard design features three 2 oz. copper ground planes, which fully shield the backplane, minimize EMI/RFI emissions susceptibility, minimize crosstalk, and maximize power distribution. In addition, the robust outer ground layers provide mechanical and EMI/RFI protection for the backplane.
