VPX Overview

VPX is a proposed ANSI standard which breaks out from the traditional connector scheme of VMEbus to merge the latest in connector and packaging technology with the latest in bus and serial fabric technology. VPX combines best-in-class technologies to assure a very long technology cycle similar to that of the original VMEbus solutions.

The Ruggedized Enhanced Design Implementation (REDI) describes how to implement layout techniques to better support cooling methodologies on specific board form factors. Currently, it covers enhanced forced-air cooling (using baffles and plenums), advanced conduction cooling (using larger and more efficient thermal interfaces), and liquid cooling. It also addresses the use of ESD covers on both sides of the board, a necessary feature for military two-level maintenance strategies.
