VXI BACKPLANES FROM BUSTRONIC UPGRADED WITH SMT COMPONENTS

FREMONT, California, Feb. 24, 2004- Bustronic Corporation, an industry leading designer and manufacturer of high performance backplanes, continues to expand and improve its VXI product offering. The 8, 11, and 13-slot "C" size backplanes now utilize SMT components, offering more choices to the customer.

The VXI backplanes come in through-hole and SMT components options. The benefit of through-hole applications is easy replacement in the field for capacitors, resistors, etc. The SMT versions offer more uniformity in solder re-flow and a more consistent and efficient manufacturing process. Bustronic VXI line offers a custom, laminated busbar to distribute ±24V, ±12V, -5.2V, and 2V throughout the backplane, rather than the more common approach of bringing these voltages to the backplane at only one or two points. As a result of this technique, the Bustronic VXlbus backplane has one of the lowest voltage drops in the industry. The use of 2 oz. copper power planes, four solid ground and two VCC planes, and distributed decoupling capacitors on all voltages helps provide the finest, most complete power distribution available.

The Bustronic VXI backplane line includes automatic active BUSGRANT and IACK jumpering, and a 4-point chassis ground that can be modified by the user to isolate the chassis ground from the digital ground. Ten-layer stripline construction provides superior performance, minimizes crosstalk, and provides for excellent RFI/EMI resistance. A panel connector for SYS Reset, and a power monitor connector are optional. The VXI backplanes are compliant with VXIbus spec.Rev. 1.4, VMEbus C.1.

Bustronic currently offers 6U size "C" backplanes in 5, 6, 8, 9, 11, and 13 slots. Versions in the 9U size "D" configuration and custom versions are also available. The company also offers VXI test extender boards.
